    The invention tends to electrical engineering, in particular to electrical insulating materials.
    The aim of the invention is to expand the scope of use by possible use for insulating wires.
    FIG. 1-5 depict embodiments and uses of insulating tape
    The insulating tape has a lentil-shaped or trapezoidal cross-section with a thickness in the middle of at least 30 microns, a maximum thickness at the edge x 5 microns and a width of at least 4 mm.
    According to a preferred embodiment, the thickness of the insulating tape in the middle part a is 30-200 microns (as a rule, the winding tapes have a thickness of 60-180 mm in this part). On either side of this part, the thickness of the tape is reduced; at the edges of the tape, it is 5 microns or less; the tape width in this case is 4-50, preferably 10-30 mm. The choice of tape thickness in the middle part, as well as the width of the tape, usually depends on the purpose of its application. ; If the winding or insulating tape is made of powdered or granular synthetic material with high heat resistance, which is not produced from the melt and is not sintered, then in this case during heat treatment (sintering) after winding the tape, for example, an electrical conductor is formed in As a result of welding the edges of the tape, as well as layers, compact homogeneous insulation. The compactness obtained with the help of the proposed tape is not comparable with the usual ribbon windings; it can be compared to extruded or obtained by pressing insulation. The particular shape of the proposed tape compared to the known ribbons with a rectangular cross section provides more reliable edge welding during sintering. . Such a practically hermetic surface is exceptionally resistant to external influences, even to the effects of aggressive media at high temperatures.
    When using the proposed tape, reliable welding is also ensured in the middle thickened area.

    tapes. Since during the winding process, it is the middle part of the tape that is stretched more strongly than the edges, -in. the subsequent sintering process, due to the corresponding volume shrinkage, the entire ribbon is pressed tightly against the base or against the lower layer of the ribbon. The proposed tape with a thickened middle part as compared to thinner tapes with the same cross section has the advantage that less layers of turns are needed to achieve the same winding thickness, therefore, fewer surfaces are welded to each other, and the risk of gripping known particles or air plugs. The electrical cables or wires insulated or wrapped by the proposed tape, as well as the tubes of heat exchangers protected by it, are therefore suitable for direct heating or heating of wet zones or baths of oil, acids and alkalis.
    Suitable materials for the proposed winding tapes are polyimide-based materials that contain carbon black as a filler to provide semiconductor properties. Due to their chemical inertness and heat resistance, fluoroplastics are suitable for this purpose, g is preferably Teflon, which.

    for example, as a sheath for conductors, it has the necessary electrical properties. Polytetrafluoroethylene (Teflon) assumes the presence of Q tetrafluoroethylene polymers that exist in a modified state in such an amount that such polymers as polytetrafluoroethylene itself cannot be obtained from a melt.
    Wound or insulating tape in sintered or unsintered form is most suitable for making coatings for stretched material. This refers to the green tape, as in the sintering process that follows the winding process, its edges and layers are welded into one compact shell. In the case of an electrical cable or wire, such a layer consisting of tapes can form an insulation of, for example, heating wires from several cores. From winding or insulating tape

    the outer sheath of the cable or wire can also be made resistant to mechanical and chemical influences; likewise, in multilayer cables or wires, one of the layers, sintered or green, may consist of heat-resistant winding or insulating tape, the latter may alternate with other polymers.
    The proposed tape can be used to protect not only electrical cables or wires, but also pipes or pipelines made from them for transporting liquid or gaseous substances heated or cooled. For example, when using metal pipes in areas exposed to corrosive media, a protective shell is required that has adequate resistance. In the chemical and petrochemical industry, pipe systems of the proposed winding tape are used.
    Dos for transporting the medium from the production site to the centers where the analysis is performed, which are heated using heating conductors or heating tapes.
    The occurrence of a hazard for metal heating conductors or tapes, as well as for other metal tubes present in the system, depends on the type of medium being transported and the possibility of diffusion, for example, of wet chlorine, gaseous HC1 or phosgene through the walls of the synthetic material, inside the pipeline (tube bundle). The sheath of the proposed tape prevents corrosion on the metal elements and, therefore, provides for overlapping edges, if the section is ab long lasting trouble free is chosen large, then the overlap is less
    operation.
    The proposed winding or insulating tape can be used in the manufacture of hollow shaped articles, for example pipes or sleeves or other elements by winding. There is no restriction on the diameter or shape of the cross section, which is inevitable in the case of extrusion. In particular, for hollow shaped products, it is advisable to use green tape with high heat resistance in order to obtain compact self-supporting pipe walls or sleeves as a result of the sintering process.
    FIG. 1-3 schematically presents the proposed tape, the cross section.
    Thus, in FIG. 1 shows a tape 1 with a smooth surface lenticular.
    the shape that has the greatest thickness, for example 80-150 microns, in the middle part a, while in sections b the thickness of the tape falls in the direction of the edges 2 to 5 mm or less.
    FIG. Figure 2 shows the heat resistant tape 3 of a trapezoidal cross section with a flat middle part a and portions b, the thickness of which decreases to the edges 4 of the tape.
    FIG. 3, the thickened middle part of the winding tape 5 is denoted by a, and the areas with thickness decreasing to zero are B.
    FIG. Figure 4 shows an example of the use of a flexible electrical wire with oil-resistant and heat-resistant teflon insulation. Multi-wire wire 6 can be made, for example, from bare, tinned, silver-plated or nickel-plated copper wire 7. Electrical insulation 8 of one or several winding layers is applied to the wire.
    tape 9, for example, made of polytetrafluoroethylene. Depending on the pitch, the edges 10 overlap each other as shown in FIG. 4, or more. It depends on
    selected ribbon shape, i.e. the thickness of sections b or the ratio a: b sharply or smoothly decreases. So, if plot a is less than a third of the sum of patches b, then a strong
    . strong. In any case, individual parameters are chosen such that the result is a uniform 5Q on a smooth outer surface. This is the case if green tape is used and sintering is performed after the winding process. In this case,
    gg is not only the tightness of the outer surface, but also a tight joint seams.
    FIG. 5 shows the use of a winding or insulating tape.
    for the manufacture of protective sheath for pipes or pipelines. Such pipes can be single (heat exchanger) or grouped with the same or similar elements (tube bundle). FIG. 5, the pipe 11 is made of, for example, copper, for protection against aggressive media, is a winding of green tape 12, which is applied, for example, in several layers, and after sintering, it forms a sealed compact shell 13.
