    SYSTEMS AND METHODS FOR AIR TREATMENT OF SUSPENDED WIRING
    CROSS REFERENCE TO RELATED ORDERS
    [001] This application claims benefit from application serial number US 62 / 504,849, entitled SYSTEMS AND METHODS FOR AERIAL TREATMENT OF OVERHEAD CABLING, filed on May 11, 2017, and hereby incorporates the same application into this document to reference title in its entirety.
    TECHNICAL FIELD
    [002] The present disclosure generally refers to the in situ aerial treatment of cables, such as suspended conductors, suspension cabling and the like.
    BACKGROUND
    [003] As the need for electricity continues to grow, so does the need for higher capacity transmission and distribution lines. The amount of power that a transmission line can deliver depends on the current carrying capacity (ampacity) of the line. The ampacity of a line, however, is limited by the maximum safe operating temperature of the bare conductor carrying the current. Exceeding this temperature may result in damage to the driver or to the transmission and distribution line accessories. The conductor temperature is determined by the cumulative heating and cooling effect on the line. The conductor is heated by ohmic losses and solar heat and cooled by conduction, convection and radiation. The amount of heat generated due to ohmic losses depends on the current (I) and electrical resistance (R) of the conductor and is determined by the relationship between
    Petition 870190111409, of 10/31/2019, p. 19/74
    2/36 ohmic losses = I 2 R. The electrical resistance (R) alone depends even more on the temperature. Higher currents and temperatures lead to greater electrical resistance, which, in turn, leads to greater electrical losses in the conductor.
    [004] Various solutions have been proposed in the art to create higher capacity transmission and distribution lines. For example, suspended conductors coated with spectral selective surface coatings are known. Such coatings can have a heat emission coefficient (E) greater than 0.7 and solar absorption coefficient (A) less than 0.3. Such coatings can be white in color to decrease solar absorption.
    [005] Before a coating, a transmission or distribution line is normally cleaned or prepared to receive the coating. Although technologies are available separately for cleaning and coating for different purposes, the technology is not suitable for cleaning all types of dirt in various line sizes. In addition, existing technologies are not suitable for cleaning and applying a coating to live (or in situ) transmission or distribution lines. Instead, these coatings can only be applied to the transmission and distribution lines during the manufacture of the lines, or at least before the installation of the lines. Many millions of linear feet of lines are installed and actively carry chain that can benefit from applying various coatings and / or other types of treatments. Furthermore, in addition to the transmission and distribution lines, other types of wires and cables (ie bridge cables, line wires, support lines, etc.) can benefit from several
    Petition 870190111409, of 10/31/2019, p. 20/74
    3/36 surface treatments and / or coatings. Therefore, a system is needed to prepare and handle suspended cabling in situ.

    DETAILED DESCRIPTION
    [019] The present disclosure provides overhead cable treatment systems and overhead cable treatment methods. Various non-limiting modalities of the present disclosure will now be described to provide a general understanding of the principles of the function, design and use of overhead cable treatment systems. One or more examples of these non-limiting modalities are illustrated in the accompanying drawings. Those skilled in the art will understand that the methods described in this document and illustrated in the accompanying drawings are exemplary non-limiting modalities, and that the scope of the various non-limiting modalities of the present disclosure is defined only by the claims. The features illustrated or described in connection with a non-limiting modality can be combined with the characteristics of other non-limiting modalities. Such modifications and variations are intended to be included within the scope of the appended claims.
    [020] The surface treatments and coatings described in this document can be applied to a variety of cables, including, but not limited to, high voltage suspended electricity transmission lines. As can be seen, these overhead electricity transmission lines can be formed in a variety of configurations and can generally include a core formed from a plurality of conductive wires. For example, cables with aluminum conductive steel (ACSR), cables supported by aluminum conductive steel (ACSS), cables with
    Petition 870190111409, of 10/31/2019, p. 22/74
    5/36 aluminum (ACCC®) and all aluminum alloy conductor cables (AAAC). ACSR cables are high-strength twisted conductors and include external conductor wires and central support wires. The external conductive wires can be formed of high purity aluminum alloys with high conductivity and low weight. The central support wires may be steel and may have the necessary strength to support the most ductile external conductor wires. ACSR cables can have a high overall tensile strength. ACSS cables are concentric braided cables and include a central steel core around which one or more layers of aluminum or aluminum alloy wire are braided. ACCC® cables, on the contrary, are reinforced by a central core formed by one or more carbon, fiberglass, aluminum oxide fiber or polymer materials. A composite core can offer a variety of advantages over a conventional aluminum or steel reinforced cable, as the combination of the composite core with high tensile strength and low thermal drop allows for longer spans. ACCC® cables can allow the construction of new lines with less support structures. AAAC cables are made with aluminum wire or aluminum alloy. AAAC cables may have a better resistance to corrosion, due to the fact that they are largely or completely made of aluminum. ACSR, ACSS, ACCC® and AAAC cables can be used as overhead cables for overhead distribution and transmission lines. Other examples of suspended high voltage electricity transmission lines include, without limitation, reinforced aluminum conductive composite cable, supplied by 3M, and fully conductor distribution and transmission lines.

    6/36 aluminum (AAC).
    [021] In addition to suspended electrical transmission cables, the systems and methods described in this document can be used to provide surface treatments and apply the coatings described in this document to a variety of other types of overhead cables without departing from the scope of this document. revelation. Some examples of overhead cable that can be treated and / or sheathed using the cable treatment systems and methods described in this document include, without limitation, bridge wires, cable treatment wires, cable car wires, hose wires, support lines and suspended electric lines for light rails. In addition, the systems and methods described in this document can be used to provide surface treatments and apply the coatings described in this document to insulated or non-insulated cables. Overhead cables according to the present disclosure can be conductive or non-conductive and can comprise any variety of materials, such as aluminum, steel, iron and so on. The overhead cable may have a generally round cross-sectional shape. In addition, in some cases, various accessories associated with the overhead cable, such as line couplers, connections, fittings and the like, can be treated and / or sheathed along with the overhead cable.
    [022] The overhead cable treatment systems and methods described in this document provide the cleaning and / or coating of the suspended cables subsequent to the installation of the cabling. In this way, these systems can be deployed to clean and / or coat suspended cables in situ (that is, suspended cables that are in their environment
    Petition 870190111409, of 10/31/2019, p. 24/74
    7/36 operational). With regard to high voltage transmission lines (ie active cables with voltages in the range of 66 kV to 345 kV), for example, the overhead cable treatment system can connect to a line and cross the line between two adjacent towers, or other spans, cleaning and / or coating the line as it moves. According to certain modalities, an aerial cable treatment system is automated and uses an image processing system so that the decision on treatment and / or coating, direction of travel, rate of travel and so on, can be made. performed by an onboard controller. An overhead cable treatment system can be driven along the overhead cable, or driven or pulled by a motorized wheel system with one or more drive wheels. In some embodiments, the wheel system may be able to adapt to various cable diameters (ie, conductor diameters) ranging from 0.5 to 1.5, or larger, as needed.
    [023] Certain aerial cable treatment systems and methods according to the present disclosure can prepare a surface of the aerial cable and then apply a surface coating or other type of treatment. The surface preparation mechanisms of the overhead cable treatment system described in this document can remove dirt and debris, such as carbon deposits, grease, mud, fertilizers, bird droppings, fungal growth, moss, soot, etc. cableway with varying sizes. The surface preparation mechanisms of the overhead cable treatment system described in this document can also play other roles.
    Petition 870190111409, of 10/31/2019, p. 25/74
    8/36 functions, such as removing ice from the cable. According to some modalities, and as described in more detail below, a return system can be implemented to adjust the operations of overhead cable treatment systems (ie, a cleaning brush rotation speed, direction of travel and / or travel rate) based on the dirt level of the overhead cable using image processing and / or based on other parameters.
    [024] The overhead cable treatment system coating mechanisms described in this document can use any of a variety of suitable coating techniques. In some embodiments, air cleaning technology is used to provide a non-contact coating process. Air cleaning technology, as described below, can be selectively adapted to handle specific coating technology, crosswinds, transport speeds, flow volume of the coating material and so on. In some embodiments, the coatings provided by the overhead cable treatment system, according to the present disclosure, are 5 to 100 microns thick, with a drying time of less than 24 hours after coating. In addition or alternatively, casing wheels, rollers or other types of casing systems can be used, such as systems that apply an atomized liquid mist to the overhead cable, as described in more detail below.
    [025] An aerial cable treatment system in accordance with the present disclosure can use optical guidance systems to identify obstacles and / or validate effectiveness
    Petition 870190111409, of 10/31/2019, p. 26/74
    9/36 of the cleaning and coating systems. In certain embodiments, for example, the image processing technology used that compares the coating with a sample model to assess the quality of the coating applied. The image processing in the present described document can use the visible spectrum and / or other spectra, such as infrared. In addition, in some modalities, using wireless / RF communication technologies or other wireless transmission protocols, an overhead cable treatment system can provide real-time images of conductors to a remote destination (ie an operator field) or a cloud-based or centralized processing system.
    [026] Referring now to Figure 1, a side view of an overhead cable treatment system 100 is depicted. Figure 2 is a top view of the aerial cable treatment system 100 depicted in Figure 1. Figures 1 and 2 represent simplified versions of the aerial cable treatment system 100, with several components removed or simplified for clarity of the illustration. The overhead cable treatment system 100 may have a housing 102 in which various components are assembled. For an overhead cable treatment system 100 that is for use with distribution and transmission lines, housing 102 may be a metallic structure within which the components are closed. Housing 102 may have Corona horns to provide safety for all components of the Corona discharge from the distribution and transmission lines.
    [027] The aerial cable treatment system 100 can be suspended on an aerial cable 198, so that the aerial
    Petition 870190111409, of 10/31/2019, p. 27/74
    10/36 overhead cable treatment 100 may cross overhead cable 198 to perform cleaning and / or other types of treatments along the length of overhead cable 198. Housing 102 may have a longitudinal geometric axis (shown as geometric axis Ll) in the Figure 2, which generally extends along aerial cable 198 when aerial cable treatment system 100 is in operation. The overhead cable treatment system 100 may have a front drive wheel 110 and a rear drive wheel 112 which are positioned each along the longitudinal geometric axis Ll. The front wheel 110 rotates about a front axle 114 and the rear wheel 112 rotates about a rear axle 116. In certain embodiments, the outer periphery of each of the front wheel 110 and the rear drive wheel 112 may be concave to form a circumferential hollow in which a portion of the overhead cable 198 is received when overhead cable treatment system 100 is suspended overhead cable 198. The front drive wheel 110 and the overhead wheel rear drive 112 can be driven by one or more drive motors in order to propel the overhead cable treatment system 100 in a forward or reverse direction along overhead cable 198. As shown, follower wheels 124, 126 can be positioned to help keep the overhead cable treatment system 100 engaged with overhead cable 198. In some embodiments, the vertical position of the follower wheels 124, 12 6 can be adjusted so that the vertical clearance between follower wheels 124, 126 and front and rear drive wheels 110, 112 can be increased or decreased to accommodate overhead cables of different
    Petition 870190111409, of 10/31/2019, p. 28/74
    11/36 diameters.
    [028] The aerial cable treatment system 100 may have an optical guidance system on board to assist in the identification of obstacles, determine when the aerial cable treatment system 100 has reached the end of a span and / or provide input for parameters operational. As shown in Figure 1, the overhead cable treatment system 100 can include one or more facing cameras 122. The overhead cable treatment system 100 can also include one or more additional cameras to provide video power to a unit image processing, like a retrospective camera. Based on the video feed provided by the forward facing cameras 122 and / or other cameras, a decision can be made as to the activation of the overhead cable treatment system 100, determination of a speed to activate the overhead cable treatment system. 100 and / or assistance in making other navigation decisions. Forward facing cameras 122 and any other cameras can be mounted in housing 102 in any suitable location that provides images suitable for an image processing unit. In some embodiments, the aerial cable treatment system 100 passes through an aerial cable span and, since it is determined, based on image processing, that an end of a span has been reached, the aerial cable treatment system 100 reverses its direction of travel, so that it can return to the original point of implantation for recovery by an operator.
    [029] According to certain modalities, the overhead cable treatment system 100 may include an assembly of
    Petition 870190111409, of 10/31/2019, p. 29/74
    12/36 cable surface preparation 150 and a cable jacket assembly 180, both of which can be mounted in housing 102. The cable surface preparation assembly 150 can include any tools or mechanisms that prepare, clean, defrost or mechanically interact with the overhead cable, such as brushes, bristles, washers, scrapers, abrasive paper, emery paper, sandpaper, rollers, and so on. Additional details regarding examples of cable surface preparation assemblies using rotating brushes are provided below with reference to Figures 3 and 4. Additional details regarding examples of cable coating assemblies are provided below with reference to Figures 5 and 6. As shown in Figure 1, the cable surface preparation assembly 150 is positioned inside the housing 102, so that when the overhead cable treatment system 100 advances in the direct direction (as indicated by arrow 120), the cable preparation assembly cable surface 150 can prepare aerial cable 198 prior to cable jacket assembly 180 by applying a jacket to the surface of aerial cable 198. Additionally, as shown in Figures 1 and 2, cable jacket assembly 180 can be coupled to the housing 102 behind the rear drive wheel 112 and follower wheels 124, 126. Using this arrangement, the rear drive wheel 112 and the wheels followed ras 124, 126 do not come in contact with the aerial cable 198 after applying a coating to avoid degradation of a recently applied coating.
    [030] Referring now to Figure 3, the cable surface preparation assembly 150 according to an example
    Petition 870190111409, of 10/31/2019, p. 30/74
    13/36 modality is represented. The cable surface preparation assembly 150 may have a cable surface abrasion assembly 160 that is arranged to scour the surface of the aerial cable 198 as the aerial cable treatment system 100 advances along the aerial cable 198. In the illustrated embodiment, the cable surface abrasion assembly 160 has a plurality of rotating brush assemblies that are used to clean the surface of the overhead cable 198. In Figure 3, the rotating brush assemblies 172, 176 are positioned on one side the overhead cable 198 and the rotating brush assemblies 174, 178 are positioned on the other side of the overhead cable 198. The relative location of the rotating brush assemblies 172, 174, 176, 178 can be selected to contact the outer surface of the overhead cable 198 as the overhead cable treatment system 100 advances over the overhead cable 198. In some embodiments, the rotating brush assemblies may have variable and / or uneven hardness include different materials. For example, the cable surface preparation assembly 150 may include a pair of relatively hard rotary brush assemblies (such as rotary brush assemblies 172 and 174) and a pair of relatively soft rotary brush assemblies (such as rotary brush assemblies 176 and 178). The rotating brush assemblies 172, 174, 176, 178 can include bristles of any suitable material, shape, structure and size. For example, examples of manufacturing materials for the bristles can include metal, polymer, natural, synthetic, non-synthetic fiber and so on. The rotating brush assemblies 172, 174, 176, 178 can be driven by any
    Petition 870190111409, of 10/31/2019, p. 31/74
    14/36 suitable drive. For example, rotating brush assemblies 172, 174, 176, 178 can be coupled to a drive motor by means of a drive belt.
    [031] As shown in Figure 3, in some embodiments, the cable surface preparation assembly 150 may include an air delivery assembly, such as a compressed air delivery assembly 164. The compressed air delivery assembly 164 it can provide air cleaning to blow particulate materials out of the 198 cable. An air cleaner can create a 360 ° air ring that attaches to the circumference of the 198 cable and cleans the surface with high air speed. In this example, when the aerial cable 198 exits the cable surface preparation assembly 150, any particles adhered to the aerial cable 198 can be cleaned and blown off its surface. The compressed air delivery assembly 164 can also remove moisture that may be in the 198 cable. A suitable air jet can operate at about 0.41 to 0.68 MPa (60 to about 100 PSI) in certain embodiments , at about 0.48 MPa (70 PSI) to about 0.62 MPa (90 PSI) in certain embodiments and at about 0.55 MPa (80 PSI) in certain embodiments. The air jet can have a speed (out of the nozzles) from about 125 mph (201.17 km / h) to about 500 mph (804.67 km / h) in certain modalities, about 150 mph (241, 4 km / h) at about 400 mph (643, 7 km / h) in certain modes and around 250 mph (402.34 km / h) at about 350 mph (563.27 km / h) in certain modes . A suitable compressed air delivery assembly 164 is the NEX FLOW ring blade air cleaner provided by Nex Flow Air Products Corp., Cincinnati, Ohio. The delivery assembly of
    Petition 870190111409, of 10/31/2019, p. 32/74
    15/36 compressed air 164 may be in fluid communication with an air compressor 166 which is mounted in housing 102 (Figure 1). As described in more detail below in relation to Figures 9, the compressed air delivery assembly 164 can generally be ring-shaped, so that an air nozzle substantially surrounds the cable 198. In other arrangements, however, an assembly The air delivery assembly of the cable surface preparation assembly 150 may include, for example, a plurality of individual air nozzles positioned to apply high speed air to the aerial cable 198. Examples of suitable air nozzles include the ATTO SUPER AIR NOZZLE , such as Model 1108SS, 1108 — PEEK, 1108SS-NPT and 1108-PEEK-NPT models supplied by EXAIR Corp., Cincinnati, Ohio. In yet another arrangement of the cable surface preparation assembly, an air delivery assembly is not used. In such arrangements, the air whirlwind created by brush assemblies rotating can serve to remove dirt and debris from the overhead cable.
    [032] In certain embodiments, the cable surface preparation assembly 150 includes an optical surface preparation inspection system 156. Additional details on an example of an optical surface preparation inspection system 156 are provided below in relation to the Figure 10. The optical surface preparation inspection system 156 can collect images of the aerial cable 198 following the abrasion assembly of the surface of the cable 160, preparing the surface of the aerial cable 198. The images can be static photos, video or combinations thereof . The images can be analyzed by processing
    Petition 870190111409, of 10/31/2019, p. 33/74
    16/36 images, both on board the overhead cable treatment system 100 and at a remote image processing unit, to determine whether the surface preparation carried out by the abrasion assembly of the cable surface 160 is sufficient. If surface preparation is sufficient, aerial cable treatment system 100 can continue to advance along aerial cable 198. If surface preparation is not sufficient, aerial cable treatment system 100 can reverse its direction of travel. , so that a portion of the aerial cable 198 can be brought into contact by the abrasion assembly of the surface of the cable 160 again. The surface of the aerial cable 198 can then be rechecked optically to determine if the surface is sufficiently prepared. The surface preparation optical inspection system 156 can be configured, for example, to capture images at fixed intervals and store the images in a localized manner on a suitable data storage (such as an SD card). In some configurations, the cameras of the 156 surface preparation optical inspection system are positioned approximately 1.5 inches (3.81 cm) away from the aerial cable 198.
    [033] While the cable surface preparation assembly 150 represents an example of a cable surface preparation assembly arrangement, other arrangements can be used. Referring now to Figure 4A, another example of cable surface preparation assembly 250 is shown. The cable surface preparation assembly 250 is similar in many respects to the cable surface preparation assembly 150 in that it includes a
    Petition 870190111409, of 10/31/2019, p. 34/74
    17/36 compressed air delivery assembly 264, an air compressor 2 66 and an optical surface preparation system 256. As provided above, however, other provisions of the cable surface preparation assembly 150 may use different types of air supply assemblies or none. The cable surface preparation assembly 250 also includes a cable surface abrasion assembly 260. As shown, this arrangement includes two rotary brush assemblies 272 and 274. The sample cable surface preparation assembly 250 also includes a chemical application system 252. chemical application system 252 can apply a chemical composition 254 to an overhead cable 298, using one or more nozzles or another suitable delivery mechanism, such as a roller. The chemical composition 254 can include any suitable chemical, such as a degreaser, a cleaning agent, steam, a lubricant, a deoxidizer and so on. Although a nozzle is shown in Figure 4A, any suitable applicator can be used to apply chemical composition 254 to aerial cable 298. According to certain modalities, chemical composition 254 can be applied by spray gun or electrodispersion gun at a pressure from about 0.068 MPa (10 psi) to about 0.31 MPa (45 psi) using controlled air pressure. In such embodiments, the spray gun nozzle can be placed perpendicular to the direction of the 298 overhead cable (for example, an angle of approximately 90 °) to achieve a uniform coating on the 298 overhead cable. In certain cases, two or more guns also can be used to obtain more efficient coatings. Figure 4B depicts
    Petition 870190111409, of 10/31/2019, p. 35/74
    18/36 is another example arrangement of the cable surface preparation assembly 250 shown in Figure 4A. The cable surface preparation assembly 250 shown in Figure 4B is shown to include the two rotating brush assemblies 272 and 274. This arrangement, however, does not include the chemical application system 252, the compressed air delivery assembly 264 , the air compressor 266.
    [034] The cable surface abrasion assembly 260 of the cable surface preparation assembly 250 is in such a position that a chemical composition 254 is applied first to the surface of the overhead cable 298 and then overhead 298 it is powered by the rotary brush assemblies 272 and 274. In other embodiments, however, the cable surface preparation assembly 250 may have a different arrangement or not have certain components (such as the rotary brush assemblies 272 and 274) or include additional components (such as additional rotary brush assemblies or additional chemical application systems).
    [035] Referring now to Figure 5, the cable jacket assembly 180 according to an example of a modality is depicted. The cable sheath assembly 180 may have a sheath applicator assembly 192 that is arranged to apply a sheath to the surface of the aerial cable 198 as the aerial cable treatment system 100 advances along the aerial cable 198. In the embodiment illustrated, the cable sheath assembly 180 has a nozzle 184 which is fluidly communicating with a sheath storage tank 182 through a liquid sheath delivery system 194. In some
    Petition 870190111409, of 10/31/2019, p. 36/74
    19/36 embodiments, a coating pump 170 is used to pump the liquid coating from the coating storage tank 182 to the nozzle 184 through the liquid coating supply system 194. The coating storage tank 182 can be refillable or the liner storage tank 182 can be a single use tank that can be replaced with a full tank as needed. The nozzle 184 can be configured to apply a coating to any of a variety of application techniques. For example, nozzle 184 may drip onto the liner, as shown in Figure 5. Or, in some cases, nozzle 184 may form a mist of atomized liquid that is a combination of liquid and compressed air.
    [036] The coating that is applied to overhead cable 198 may vary based on the type of cable. In certain embodiments, the coating is a liquid with a viscosity of more than 5 seconds (Zahn cup -3). The liquid can be inorganic (for example, silicate) or organic polymer (for example, thermoplastic or thermoset polymer). For drying type coatings, the coating may have a softening temperature greater than 90 ° C, as for suspended cables with a maximum operating temperature of 90 ° C. For overhead cables with a higher operating temperature, the jacket softening temperature may be higher, as appropriate for operating conditions. In certain embodiments, the coating applied by the cable jacket assembly 180 has a thickness in the range of 5 to 100 microns or 10 to 30 microns. The coating can have a drying time of less than 24 hours and less than
    Petition 870190111409, of 10/31/2019, p. 37/74
    20/36 hours in some cases. The overhead cable treatment system 100 can move the cable jacket assembly 180 along the overhead cable 198 at an appropriate speed based on the type of sheath and the sheath application process. In an example of a modality, the speed of the aerial cable treatment system 100 is in the range of 91.44 cm / minute (3 feet / minute) to 3,048 cm / minute (100 feet / minute). The coating applied by the cable jacket assembly 180 may have an emissivity greater than 0.5 or an emissivity greater than 0.7. The coating may have an ice adhesion value of less than 250 kPa. As should be seen, however, the particular characteristics of the coating applied by the cable sheath assembly 180 will depend on the type of cable being sheathed and its operational parameters.
    [037] Still referring to Figure 5, a compressed air delivery assembly 186 can be positioned to supply compressed air to the surface of the overhead cable 198 following the application of a coating by the coating applicator assembly 192. For example, when a drip feed coating applicator assembly 192 is used, the compressed air delivery assembly 186 can blow air from an air compressor 188 to distribute the drip coating material evenly around the surface of the overhead cable 198. Cleaning the air provided by the compressed air delivery assembly 186 may allow the sheath to penetrate grooves between the wires on the surface of the overhead cable 198. This air cleaner can operate under conditions similar to those of the air cleaner in mounting air. surface preparation
    Petition 870190111409, of 10/31/2019, p. 38/74
    21/36 of cable 150. Instead of an air cleaner, other forms of air supply can be used, such as one or more air nozzles positioned to distribute the drip coating material. The cable sheath assembly 180 may also include an optical sheath inspection system 190. Additional details on an example of an optical sheath inspection system are provided below in relation to Figure 10. The optical sheath inspection system 190 may collect images of aerial cable 198 subsequent to the application of a coating by mounting the coating applicator 192. The images can be static photos, video or combinations thereof. The images can be analyzed through image processing, both on board the overhead cable treatment system 100 and at a remote image processing unit, to determine whether the coating applied by the 192 applicator assembly is sufficient. In some embodiments, if the surface coating is sufficient, the aerial cable treatment system 100 can continue to advance along the aerial cable 198. If the surface coating is not sufficient, the aerial cable treatment system 100 can reverse its direction of travel, so that a sheath can be reapplied to a portion of the aerial cable 198. However, care can be taken that the drive wheels do not come into contact with the uncured or wet section of the sheath. The surface of the aerial cable 198 can then be rechecked optically to determine if the coating is sufficient.
    [038] Although the cable jacket assembly 180 represents an example of a cable assembly arrangement
    Petition 870190111409, of 10/31/2019, p. 39/74
    22/36 cable sheath, other arrangements can be used. Referring now to Figure 6, another example of cable jacket assembly 280 is shown. Cable sheath assembly 280 is similar in many respects to cable sheath assembly 180 in that it includes an optical sheath inspection system 290, a sheath applicator assembly 292 that applies a sheath stored in a sheath storage tank 282 and casing pumps 270. The casing applicator assembly 292, however, includes casing wheels 276, 278 which are in fluid communication with a liquid casing supply system 294. Casing wheels 27 6, 278 can be rolled along the aerial cable 298, making contact with it and applying a liquid coating of the coating wheels 276, 278 to the aerial cable 298. An optical coating inspection system 290 can be used to assess the sufficiency of the liquid coating that was applied by the coating wheels 276, 278. A coating composition can alternatively be applied by a spray gun (for example, electrostatic spray gun) in certain modalities. A spray gun can apply the coating composition using a pressure of about 0.06 MPa (10 psi) to about 0.31 MPa (45 psi). In such embodiments, the spray gun nozzle can be placed perpendicularly (for example, at about 90 °) to the longitudinal direction of the substrate to obtain a uniform coating on the substrate. In certain embodiments, two or more dispersion guns can be used to obtain more efficient coatings or
    Petition 870190111409, of 10/31/2019, p. 40/74
    23/36 uniforms. The thickness and density of the coating can be controlled by the viscosity of the mixture, gun pressure and speed of the associated overhead cable treatment system. In some embodiments, the coating applicator assembly 292 comprises a foam-based applicator that is configured to apply foam to the overhead cable 298.
    [039] Referring now to Figure 7, an aerial cable treatment system with multiple cars 300 is depicted. The multi-car aerial cable treatment system 300 may include a first car 302 and a second
    car 304 that can to be deployed separately on a cable aerial 398. Both the cars can be translatable independently to long cableway 398 simultaneously, so the second car 304 follow the
    first car 302 along cable 398. Alternatively, the first car 302 can complete its crossing of cable 398 before the second car 304 is coupled with cable 398. In the illustrated embodiment, the first car 302 is used to translate a cable surface preparation assembly 350 in a first direction (indicated by arrow 320) along aerial cable 398 and the second carriage 304 is used to separately translate a cable jacket assembly 380 along aerial cable 398 in the first direction . Each of the first and second cars 302, 304 can include one or more cameras 322 to provide images to the respective image processing systems to assist in navigating the first and second cars 302, 304 along the cable 398.
    [040] Each of the 302 and 304 cars can be built
    Petition 870190111409, of 10/31/2019, p. 41/74
    24/36 similarly to the overhead cable treatment system 100 shown in Figures 1 and 2. For example, the first car 302 may have a front wheel 310 and a rear wheel 312 that are coupled to a first housing 30 6 and which can be driven by a motor to drive the first car 302 along the cable 398. The follower wheels 324, 326 can assist in maintaining the engagement of the first car 302 on the cable 398. Each of the traction wheels 310 , 312 and follower wheels 324, 326 can have similar diameters as shown, or have different diameters. Each of the front drive wheel 310 and the rear drive wheel 312 can be positioned along a longitudinal axis of the first carriage 302, shown as the axis L2 in Figure 7. The cable surface preparation assembly 350 may include components similar to those discussed above in connection with the cable surface preparation assembly 150 and / or the cable surface preparation assembly 250.
    [041] The second car 304 may have a front wheel 328 and a rear wheel 330 that are driven by an engine to drive the second car 304 along overhead 298. The follower wheels 332, 334 can help maintain the engagement of the second car 304 on the aerial cable 398. Each of the front drive wheels 328 and the rear drive wheel 330 can be positioned along a longitudinal axis of the second car 304, shown as the axis L3 in Figure 7. The cable sheath assembly 380 may include components similar to those discussed above in connection with the cable sheath assembly 180 and / or the cable sheath assembly
    Petition 870190111409, of 10/31/2019, p. 42/74
    25/36 cables 280. In addition, as shown in Figure 7, both the front drive wheel 328 and the rear drive wheel 330 can be attached to a second housing 308, so that both come into contact with the overhead cable 398 prior to applying a jacket by the cable jacket assembly 380 when the second carriage 304 is moving in a forward direction, as indicated by the arrow in Figure 7.
    [042] During the operation of the multi-car aerial cable treatment system 300, for example, an operator can send the first car 302 under an aerial cable 398 to prepare the surface of the aerial cable 398 for a sheath. The first carriage 302 can scour the surface, apply a chemical treatment to the surface and / or perform other surface preparation functions. Once the first car 302 has crossed the gap, it can automatically return to the starting point of implantation. The operator can then remove the first carriage 302 from cable 398 and engage the second carriage 304 with cable 398. The second carriage 304 can then traverse the gap to apply a coating to the surface of cable 398. Depending on the type of coating applied, the second car 304 can automatically return to the starting point of implantation or remain at the end of the span, so that the operator can disengage the second car 304 from the cable 398 at that point.
    [043] Although the first car 302 and the second car 304 in Figure 7 are self-propelled and contain onboard drive assemblies, this revelation is not so limited. In some modalities, for example, a propulsion car
    Petition 870190111409, of 10/31/2019, p. 43/74
    A separate 26/36 can be used that has an onboard drive assembly. The drive car can pull (or drive) one or both cars that have an onboard cable surface preparation assembly and / or a cable surface preparation assembly, but do not include an onboard drive assembly. Using this approach, the propulsion unit can include one or more drive wheels that are driven by a drive assembly. With trolleys housing the cable surface preparation assembly of the plate and the cable surface preparation assembly without the need for an independent drive assembly, the total weight of these trolleys can be reduced. Therefore, in some embodiments, a cable treatment system may include a propulsion car, with a first car carrying a cable surface preparation assembly, and a second car carrying a cable surface preparation assembly. The propulsion unit can be configured to move each of the first and second cars over an aerial cable, separately or simultaneously. According to another embodiment, a cable treatment system can include a propulsion car and a car that carries a cable surface preparation assembly and a cable surface preparation assembly.
    [044] According to some modalities, an overhead cable treatment system may include a cable access assembly to assist in the assembly and disassembly of the overhead cable treatment system on an overhead cable. Referring to figures 8A to 8D, an example of an overhead cable treatment system 400 that has a cable access assembly 436 is
    Petition 870190111409, of 10/31/2019, p. 44/74
    Pictured 27/36. The 436 cable access assembly is simplified for clarity of illustration. The aerial cable handling system 400 is similar to the aerial cable handling system 100 in that it includes a forward facing camera 422, a front drive wheel 410, a rear drive wheel 412 and follower wheels 424, 426 , 432. The overhead cable treatment system 400 also has a housing 402 in which a cable surface preparation assembly 450 and a cable jacket assembly 480 are mounted. It should be noted, however, that in some embodiments, the overhead cable treatment system 400 may include only a cable surface preparation assembly 450 or a cable jacket assembly 480. In the illustrated embodiment, the cable treatment system overhead cable 400 includes cable access assembly 436 to assist in mounting and dismounting an overhead cable system 498. Cable access assembly 436 may include follower wheels 424, 426, 432 that are connected to housing 402 through the arms 438 that rotate around pivot points 440 each. In some embodiments, various types of cross clamps 442 or other mechanical characteristics can assist with the rotation of the components of the cable access assembly 436 between various positions.
    [045] Figures 8A to 8D represent a progression of coupling the aerial cable treatment system 400 to aerial cable 498 using cable access assembly 436. Referring to Figure 8A, cable access assembly 436 is shown in a first position, before being loaded onto an overhead cable. In order to prepare the aerial cable treatment system 400 for coupling with an aerial cable, the assembly of
    Petition 870190111409, of 10/31/2019, p. 45/74
    28/36 cable access 436 can be rotated or rotated to a second position, as shown in Figure 8B. As shown, in the second positions, the lower components are removed from the upper components to provide access to a cable receiving channel 414, which generally extends longitudinally through the overhead cable treatment system 400.
    [046] Although the cable access assembly 436 is in the second position, the aerial cable treatment system 400 can be suspended on aerial cable 498, as shown in Figure 8C. Once in place, cable access assembly 436 can be rotated to its original position and locked in place, so that overhead cable 4 98 is secured within cable receive channel 414, as shown in Figure 8D. The overhead cable treatment system 400 can then be conducted over overhead cable 498 in the direction indicated by arrow 420 to prepare and / or cover overhead cable 498. To disengage overhead cable treatment system 400 from overhead cable 498, the cable aerial 498 can be rotated to the second position (i.e., as shown in Figure 8C) so that aerial cable 4 98 can be removed from cable receiving channel 414.
    [047] Referring now to Figure 9, an example of an air delivery assembly is depicted. The air supply assembly example in Figure 9 is a compressed air delivery assembly 564 which may be similar to the compressed air delivery assemblies 164, 264 and 186 shown in Figures 3 to 5. The compressed air delivery assembly 564 may have an annular air nozzle 568 that is in fluid communication with a compressed air source, such as an air compressor.
    Petition 870190111409, of 10/31/2019, p. 46/74
    29/36 air. In other arrangements, however, different nozzle arrangements or high-speed air supply techniques can be used. For overhead cable treatment systems that include multiple compressed air supply assemblies, a single air compressor can be used that is in fluid communication with a plurality of 564 compressed air supply assemblies. Valves, such as solenoids, can be positioned between the compressed air supply assemblies and the air compressor, so that the air compressor can selectively supply compressed air to a single compressed air delivery assembly at a time. The annular air nozzle 568 can be sized to surround a substantial portion of an overhead cable 598. In some embodiments, the compressed air delivery assembly 564 has a cable receiving channel 514 through which overhead cable 598 passes when an associated overhead cable treatment system is attached to overhead cable 598. In other embodiments, a portion of the compressed air distribution assembly 564 may be a component of a cable access assembly (such as the 436 cable access assembly) which rotates, or otherwise moves away from, a stationary portion of the compressed air delivery assembly 564 to allow proper placement of the overhead cable 598 with respect to the compressed air delivery assembly 564.
    [048] Referring now to Figure 10, an example of an optical coating inspection system 690 is depicted. This 690 optical coating inspection system may be similar to the optical coating inspection systems 190 and 290 shown in Figures 5 and 6. In addition, the systems
    Petition 870190111409, of 10/31/2019, p. 47/74
    30/36 optical preparation preparation inspection 156 and 256 shown in Figures 3 and 4 can be constructed similarly to the optical coating inspection system 690. The optical coating inspection system 690 may have a ring support 618 on the which a plurality of 696 inspection cameras are mounted. In the illustrated embodiment, the 690 optical coating inspection system has three 696 inspection cameras that are mounted around the 618 ring bracket at approximately 120 ° intervals to provide 360 ° inspection capabilities. Accordingly, the three 696 inspection cameras can provide images of the entire surface of the 698 cable. In other embodiments, a greater or lesser number of 696 inspection cameras can be used. In some embodiments, ring support 618 has a cable receiving channel 614 through which overhead cable 698 passes when an associated overhead cable treatment system is attached to overhead cable 698. Inspection cameras 696 can provide power to video / image to a local or remote image processing system, so that real-time image processing can be performed. In some embodiments, the 690 optical coating inspection system is positioned within a closure that provides a constant level of light intensity in order to increase the efficiency and accuracy of image processing. In addition, in some embodiments, the images collected by the 696 inspection cameras are provided to a human operator (ie, on a ground station interface) that examines the images and determines the operating parameters of the associated overhead cable treatment system.
    [049] Figure 11 depicts examples of brush assemblies

    Rotating 31/36 772 and 774 according to various non-limiting modalities. The rotary brush assemblies 772 and 774 are similar to the rotary brush assemblies 172, 174, 176 and 178 illustrated in Figure 3. The bristles in Figure 11, however, have been removed for clarity in the illustration. The rotating brush assembly 772 has a first rotating hub 776 and the rotating brush assembly 774 has a second rotating hub 778. Each of the first rotating hub 77 6 and the second rotating hub 778 may have holes through which the bristles can be installed, so that the bristles generally extend perpendicular to the surface of the cubes. Each of the rotating brush assemblies 772 and 774 can also be operationally coupled to a drive motor. In the illustrated embodiment, the first rotary brush assembly 772 is operationally coupled to a drive motor 780 and the second rotary brush assembly 774 is operationally coupled to a drive motor 782. In other embodiments, a single motor The drive is operable to drive multiple rotating brush assemblies. The material and level of hardness of the bristles may vary. In some embodiments, for example, stainless steel bristles are used. In relation to the first rotating hub 776, it can have a final outside diameter (shown as D1) and a central outside diameter (shown as D2) with the final outside diameter (Dl) greater than the central outside diameter (D2). In another embodiment, as shown in Figure 11, each of the first rotating hub 776 and the second rotating hub 778 extends from the central outer diameter to the final outer diameter. Such an enlargement forms

    32/36 a concavity between the two opposite sides of the rotating hubs 776, 778. During operation, an aerial cable 798 can be positioned so that a first portion (i.e., the upper portion) of the aerial cable 798 is received in the concavity of the first rotating hub 776 and a second portion (ie, lower portion) of the overhead cable 798 is received in the concavity of the second rotating hub 778. In this arrangement, the bristles come into contact with the entire outer surface of the overhead cable 798 when the hubs rotary 776, 778 rotate, thus removing dirt, debris, rust and / or other particles.
    [050] Figure 12 depicts an exemplary control system for an overhead cable treatment system 800. Although the overhead cable treatment system 800 has a cable surface preparation system 824 and a cable covering system 834 , this revelation is not so limited. It should be noted that similar control systems can be used for overhead cable treatment systems having only a cable sheath system or a cable surface preparation system. A controller 804 is in communication with each of the various systems / modules of the overhead cable treatment system 800, such as an optical system 810, a drive system 818, the cable surface preparation system 824 and the coating system. 834 cables. The 804 controller can also communicate with other integrated modules, such as an 802 data input / output module. The 802 data input / output module can, for example, provide wireless or wired communication functionality. The 802 data input / output module can transmit / receive

    33/36 information (such as alarms, images, etc.) between an image processing decision engine application and an earth station. The ground station can be equipped with a human-machine interface for user interaction. The overhead cable treatment system 800 can also include a power source 806, such as the battery, used to power the embedded electronics and the various drive motors, pumps, solenoids, compressors, cameras and so on.
    [051] The optical system 810 of the overhead cable treatment system 800 may include the various cameras used during operation, such as 812 forward facing camera (or cameras), 814 surface preparation camera (or cameras) and / or surface-coated camera (or cameras) 816. The 818 drive system can include several components that drive the overhead cable treatment system 800 over an overhead cable, such as 820 drive motor (or motors) and drive wheels 822.

The cable sheath system 834 may include a pump 836, a tank level sensor 840, a compressor 838 and an air nozzle 842. In certain embodiments, compressor 828 and compressor 838 are the same compressor. The 804 controller can also receive input from one or more 844 sensors. Example 844 sensors can include a temperature sensor, a battery status sensor, a speed sensor, an altitude sensor, an angle sensor,

    34/36 slope and so on. Based on the inputs of sensors 844, controller 804 can determine the drive speed, the drive direction, among other operational parameters.
    [052] Figure 13 depicts an example of an operating environment for a 900 cable management system in accordance with the present disclosure. As shown, overhead cable treatment system 900 is coupled with overhead cable 998 which is a high voltage transmission line. The aerial cable treatment system 900 is shown traversing in a direct direction, as shown by arrow 920, along aerial cable 998 between a first tower 910 and a second tower 912. As it passes through aerial cable 998, the surface can be cleaned and / or coated, depending on the configuration of the 900 overhead cable treatment system.
