    [0002] Cover for protection and insulation of cables in electrical supply channels
    [0003] The object of the invention relates, in general, to a cover for protection and insulation of cables in electrical power supply channels. More in particular, the object of the invention refers to a cover that, forming part of the channel installed in civil works, keeps the cables hidden in the place where they must be protected; and allows said cables to emerge outside the channel where they are located when work needs require it.
    [0005] In the current State of the Art, channels are known to protect electrical supply cables. In, for example, the preceding documents ES1080229 and EP3244501 two of them are described that use a cover mounted fixed and coplanarly with the ground to cover the cables with the possibility of accessing them when the work needs require it.
    [0007] These known covers are structured in at least one main body that can be covered both on the front and on the back. The minimum required benefits are determined by different standards: DIN22102 standard for the main body and for the thickness of the coatings; and standards DIN53504, DIN53505, DIN53516, DIN53479 for breaking load, elongation at break, hardness, abrasion and density of coatings.
    [0009] The applicant has verified that the current covers (known precedents), although they comply with the minimum required regulations, present low flexibility and breaking load: their technical characteristics, structure and performance make them have a very short useful life, particularly in work environments with high wear loads and / or wide opening angles when subjected to high loads and / or very frequent cycles.
    [0010] The cover for protection and insulation of cables in electrical supply channels according to the invention overcomes these limitations. Using particular components in combination with their sizing, it manages to increase the breaking load (both longitudinal and transverse), as well as increase hardness, abrasion and density of the coatings and increase the opening angle up to 90 °, which ultimately translates into in a cover with higher performance and, simultaneously, lighter and more flexible than known covers. It is characterized because it is structured in a one-piece body, formed by at least one fabric canvas and a metallic braker bonded with rubber, the dimensions of which are approximately 395 mm ± 5mm wide; length of 140m and thickness of 20mm ± 10% that weighs approximately 11.75Kg / m and is mounted covering the entire set of the channel; and where the composition (% by weight) of said one-piece body is approximately 52% rubber; 26% loads; 10% plasticizers. The remaining 12% is the combination of, at least, the fabric canvas and the metallic braker.
    [0012] Based on this basic structuring, any alternative embodiments that do not alter, change or modify the proposed essentiality are included in the object of the invention. In particular, the cover for protection and insulation of cables in electrical supply channels according to the invention is also characterized in that:
    [0014] • the composition (% by weight) of the rubber is approximately 40% chloroprene rubber and 60% natural rubber, styrene-butadiene rubber and nitrile rubber combined;
    [0016] • the composition of the woven canvas is polyester warp and nylon weft;
    [0018] • The composition of the metallic braker is a dipped nylon warp and weft cables, made of copper and zinc, with a composition (% by weight) of approximately 63.5% copper and 36.5% zinc.
    [0020] Additionally, the cover for protection and insulation of cables in electrical supply channels according to the invention is also characterized in that said one-piece assembly is covered both on its front and on its back. Said coverings are made of neoprene, with a thickness of «3.50 mm .; breaking load> 17 N / mm2; elongation at break> 400%; hardness 62 ± 5 ° ShoreA; abrasion <130mm3 and density 1.18 ± 0.05g / cm3.
    [0022] Additionally, said cover includes longitudinal grooves that contribute to its flexibility.
    [0024] Other configurations and advantages of the invention can be deduced from the following description, and from the dependent claims.
    [0026] To better understand the object of the invention, a preferred form of embodiment is shown in the attached figures, susceptible to accessory changes that do not alter its foundation. In this case:
    [0027] Figure 1 represents a general section in elevation of a cover for protection and isolation of cables in electrical power supply channels, according to the invention, arranged on the channel (CV) where the electrical supply cables (C) are located, for a realization example.
