Corrosion-resistant insulating overhead cable

Abstract

The invention discloses a corrosion-resistant insulating overhead cable, including a cable body, a compression ring, a stretching section, an outer protection layer, conductor wires and an installation groove. The cable body is eternally wrapped by the outer protection layer, the stretching section sleeves the outer part of the outer protection layer, the inner side of the outer protection layer is provided with an armor layer, the compression ring sleeves the outer part of the stretching section, and the surface of the armor layer is provided with burrs. The corrosion-resistant insulating overhead cable provided by the invention is scientific and reasonable in structure and is safe and convenient to use; an abrasion-resistant layer and a flame-retardant water-resisting layer are arranged,and thus abrasion resistance of the cable can be improved, a semiconductive shielding layer is arranged, and thus the cable has an anti-interference capability and has a magnetic field characteristicof balancing a surrounding electric field, the burrs, a steel wire mesh and the conductor wires are arranged, and thus the cable has the characteristics of preventing bug or animal bites and meltingice and snow; and the design not only prolongs the service life of the cable, but also improves the characteristics of flame retardance, watertightness, tension resistance, abrasion resistance and corrosion resistance of the cable.

Description

technical field [0001] The invention relates to the technical field of insulated overhead cables, in particular to a corrosion-resistant insulated overhead cable. Background technique [0002] The cable wire is usually a rope-like cable twisted by several or several groups of wires [at least two in each group]. Each group of wires is insulated from each other and is often twisted around a center. Highly insulated covering layer. Cables and cables refer to materials used for power, communication and related transmission purposes. There is no strict boundary between "wires" and "cables". The product is called a wire, the one without insulation is called a bare wire, and the others are called a cable; the conductor with a larger cross-sectional area (greater than 6 square millimeters) is called a large wire, and the smaller one (less than or equal to 6 square millimeters) is called a small wire. Wires, insulated wires are also called cloth wires. Aerial cables are a kind of ca...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a corrosion-resistant insulated overhead cable, which can effectively solve the problem that the above-mentioned background technology does not have a wear-resistant layer and a flame-retardant water-proof layer, which cannot improve the wear resistance of the cable, and cannot make the cable have flame-retardant and waterproof properties. Advantages, the service life of the cable cannot be improved, there is no semi-conductive shielding layer, the cable cannot have anti-interference ability and magnetic field characteristics to balance the surrounding electric field, there is no stretch section, glass fiber layer, shock-absorbing shrapnel and anti-corrosion lubrication The grease layer cannot make the cable have the characteristics of tension resistance, corrosion resistance, tensile force and shock absorption. Without burrs, steel wire mesh and conductor wire, the cable cannot be protected from insects or animal bites, and cannot be better protected cable problem
