Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, and more specifically to a wear-resistant electric wire. Background Art

[0002] At present, the existing civilian wires have obvious problems of insufficient wear resistance when used in some areas with severe wind and sand, which causes the outer surface of the wires to be quickly worn away by wind and sand, not only causing difficulties in power transmission, but also easily causing leakage accidents. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a wear-resistant electric wire to solve the problem of the above-mentioned background technology that the existing civilian electric wires have obvious insufficient wear resistance when used in some areas with severe wind and sand, which causes the outer surface of the wire to be quickly worn by wind and sand, which not only causes difficulties in power transmission, but also easily causes leakage accidents.

[0004] The utility model provides the following technical solution: including a transmission line insulation layer, a plurality of transmission line bodies are arranged inside the transmission line insulation layer, and the transmission line bodies are all centrally symmetrically distributed along the axis of the transmission line insulation layer, and a braided sheath is fixedly installed on the outer surface of the transmission line insulation layer, and a structural reinforcement sheath is fixedly installed on the outer surface of the braided sheath, and the main body material of the braided sheath is Kevlar fiber, and the main body material of the structural reinforcement sheath is silicone rubber. When in use, the transmission line insulation layer is a preliminary outer skin structure, and the outer sheath of the transmission line insulation layer is provided with a braided sheath, and the main body of the braided sheath is Kevlar fiber, which is a very strong wear-resistant material, which can not only greatly strengthen the external structure of the transmission line insulation layer, but also has the functions of impact resistance, bending resistance, and physical damage resistance. The silicone rubber of the structural reinforcement sheath can further enhance the structural strength and wear resistance, and effectively solve the problem of obvious lack of wear resistance of existing civil wires in some areas with severe wind and sand in actual use, which causes the outer surface of the wire to be quickly worn by wind and sand, which not only causes power transmission difficulties, but also easily causes leakage accidents.

[0005] Furthermore, a layer of anti-corrosion sheath is fixedly installed on the outer surface of the structural reinforcement sheath, and the main material of the anti-corrosion sheath is polyurethane. When in use, the main material of the anti-corrosion sheath is polyurethane, which is a material with good corrosion resistance and can also play a good anti-corrosion role in extreme environments.

[0006] Furthermore, a spiral anti-wear sheath is fixedly installed on the outer surface of the anti-corrosion sheath, and the main material of the spiral anti-wear sheath is fluororubber. When in use, the spiral anti-wear sheath is spirally installed on the surface of the anti-corrosion sheath, and the spiral anti-wear sheath can enhance friction and reduce the contact area between the anti-corrosion sheath and external friction, so that the cable as a whole has better anti-friction ability.

[0007] Furthermore, the transmission line insulation layer and the braided sheath, the braided sheath and the structural reinforcement sheath, the structural reinforcement sheath and the anti-corrosion sheath, the anti-corrosion sheath and the spiral anti-wear sheath are all connected by ultrasonic non-metallic welding. When used, the ultrasonic non-metallic welding process can more firmly install different non-metallic materials together than chemical glue bonding, and prevent them from falling off from each other.

[0008] Furthermore, a fire-retardant layer is fixedly installed on the inner wall of the insulation layer of the transmission line, and the main body of the transmission line is located inside the fire-retardant layer. When in use, when a short circuit occurs in the main body of the transmission line and a fire occurs, the fire-retardant layer can prevent the fire from further extending and expanding, thereby enhancing the overall safety performance.

[0009] Furthermore, the gap between the power transmission line body and the fire retardant layer is uniformly filled with a filling support layer to fix and support the structure of the power transmission line body inside the fire retardant layer.
