Bending-resistant drag-wear-resistant comprehensive towline cable

Abstract

The invention discloses a bending-resistant drag-wear-resistant comprehensive towline cable, comprising a middle cable core, a belting layer, a total shielding layer and a sheath, wherein the middle cable core is formed by twisting a plurality of wire cores without twisting and comprises a signal wire core, a control wire core and a power wire core. According to the invention, wire core conductorsare tightly twisted, a lay ratio of the inner layers of the wire core conductors is not more than 16 times, a lay ratio of the outer layers of the wire core conductors is not more than 12 times, andpolyurethane is employed for the insulating layers of the cable cores; the cable cores have bending resistance and are not prone to core breaking and cracking, and the sheath is made of a polyurethanematerial, so the bending resistance and drag wear resistance of the whole cable are enhanced and the towline cable is not prone to wearing; the towline cable disclosed by the invention is simple in structure, and has high bending resistance, drag wear resistance and greatly prolonged service life; and the cable cores of the cable can complete transmission of a variety of information and energy, so the comprehensive application performance of the cable is high, and the cable can be applied to various towline moving places.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a bending-resistant and wear-resistant integrated towline cable. Background technique [0002] In the occasion where the equipment unit needs to move back and forth, in order to prevent the cables from being entangled, worn, pulled off, hanging and scattered, the cables are often put into the cable drag chain to protect the cables, and the cables can also move back and forth with the drag chain. A high-flexibility special cable that can move back and forth with the towline and is not easy to wear is called a towline cable. The towline cable is mainly used in: industrial electronic systems, automatic production lines, storage equipment, robots, fire protection systems, cranes, CNC machine tools and Metallurgical Industry. [0003] At present, there are the following situations in ordinary towline cables: 1. The conductors used in ordinary products are not tightly twisted, and the ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are the following situations in ordinary towline cables: 1. The conductors used in ordinary products are not tightly twisted, which is easy to break the core in the towline system; 2. Ordinary products use polyvinyl chloride material as insulation, which is easy to crack in the towline system; 3. Ordinary products use polyvinyl chloride material as the sheath, which is easy to wear in the towline system; 4. Ordinary products have a single insulated core function
