Problems solved by technology

Traditional power cables can only provide power and cannot move quickly and frequently with equipment
Traditional cables also have disadvantages such as difficult installation, high cost, easy deformation of the cable and short service life.
With the rapid development of modern hoisting machinery in the direction of high technology, the tonnage of hoisting is gradually increasing, and the speed of travel is accelerating. The traditional cables are far from meeting the above needs. The following problems often occur: the use of towing cables is different from that of general The situation is different. The cable body needs to withstand frequent back and forth bending, while the ordinary rubber insulated cable is simply bent and moved, so special attention should be paid to the design of the cable so as not to shorten the service life of the cable

Embodiment Construction

[0013] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a twist-resistant and tensile-resistant tow cable proposed by the present invention.

[0014] refer to figure 1 , the present invention proposes a twist-resistant and tensile-resistant towing cable, which includes a cable core formed by nineteen conductors 1 arranged in parallel and vertically.

[0015] Inside the conductor 1 is a wire 11 made of ten oxygen-free copper wires and ten thin steel wires twisted, and the wire 11 is covered with an insulating layer 2 of nitrile insulating material, so that the wires 11 are insulated from each other and strengthened. Conductor stretch resistance.

[0016] All conductors 1 are covered with a non-woven fabric wrapping layer 2 with a concave-convex texture. The non-woven fabric wrapping layer 2 binds nineteen conductors 1 together from the outside, and stabilizes the structure of all conductors 1. At the same time the conductor 1 has a space for movem...

Abstract

The invention discloses a distortion-resistant tensile festoon cable comprising a cable core formed by longitudinally arranging a plurality of conductors in parallel. Each conductor comprises a guide line in the middle and an insulation layer wrapping the guide line, wherein the guide line is formed by twisting one or more anaerobic copper wires and one or more small-gauge wires. The cable core is wrapped with a non-woven wrapping layer, the non-woven wrapping layer is wrapped with a reinforcement layer, the reinforcement layer is wrapped with an inner sheath, a lubrication layer is arranged outside the inner sheath, and the lubrication layer is wrapped with an outer sheath. The distortion-resistant tensile festoon cable is simple in structure, good in electrical conductivity, high in distortion resistance, capable of conducting high-speed reciprocating movement and long in service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a twist-resistant and tensile-resistant towing cable. Background technique [0002] At present, large-scale hoisting machinery needs strong electric support during operation. Traditional power cables can only provide power and cannot move quickly and frequently with equipment. Traditional cables also have disadvantages such as difficult installation, high cost, easy deformation of the cable, and short service life. With the rapid development of modern hoisting machinery in the direction of high technology, the tonnage of hoisting is gradually increasing, and the speed of travel is accelerating. The traditional cables are far from meeting the above needs. The following problems often occur: the use of towing cables is different from that of general The situation is different. The cable body needs to withstand frequent back and forth bending, while the ordinary rubber insulated ca...
