Problems solved by technology

[0003] The technical problem to be solved by the present invention is the traditional cable. For the main cable and the sub-cable interface, the cable interface is easily disconnected when being dragged and moved or subjected to external wear, and the cable cannot meet the flame-retardant performance and waterproof performance. Affect the normal operation of the power cable, the purpose is to provide an environmentally friendly wear-resistant and tensile power cable, so that the main cable and the slave cable interface have strong wear-resistant and tensile properties, and protect the cable from external damage and shorten the service life

Embodiment 1

[0025] Such as Figure 1~3 As shown, the present invention provides an environment-friendly wear-resistant and tensile power cable, including a master cable 1 and a slave cable 2, the master cable 1 and the slave cable 2 are arranged in parallel, and the master cable 1 and the slave cable 2 are connected through a connecting joint 3, The connecting joint 3 can adopt a C-shaped clamp, and the cable 2 includes a conductor 21, an insulating layer 22 and a sheath 23, and the sheath 23 is embedded with two steel wires 24; The steel wire 24 is matched with the through hole 4, and the steel wire 24 at the access end of the cable 2 is inserted into the through hole 4; The limiting groove 5, the steel wire 24 stretches out of the through hole 4 sections and bends into the limiting groove 5; the connecting joint 3 is provided with a sheath 6.

Embodiment 2

[0027] Further improvement on the basis of Example 1, an environment-friendly wear-resistant and tensile power cable, the sheath 6 sequentially includes a polyethylene sheath, a low-smoke halogen-free tape, a water-blocking tape and a steel tape from the inside to the outside . The low-smoke and halogen-free wrapping tape is made of low-smoke, halogen-free and flame-retardant glass cloth oxygen-insulating tape; the water-blocking tape is double-sided insulating and water-blocking wrapping tape.

[0028] The insulating layer 22 of the secondary cable 2 adopts a nylon insulating layer, and the sheath 23 adopts a high-density polyethylene protective layer.

Abstract

The invention discloses an environment-friendly wear-resistant and tensile power cable, which includes a main cable and a slave cable, the master cable and the slave cable are arranged in parallel, and the master cable and the slave cable are connected through a connecting joint, and the slave cable includes a conductor and an insulating layer and a sheath, the sheath is embedded with 2 to 4 steel wires; the connecting joint and along the longitudinal direction of the cable are provided with through holes matching the steel wires, and the steel wires from the cable access end The wire is inserted into the through hole; and a limit groove is provided on the connecting joint near the through hole at the insertion end of the steel wire, and the steel wire stretches out of the through hole and is bent into the limit groove; A protective cover is provided outside the connecting joint. Make the main cable and the slave cable interface have strong wear resistance and tensile properties, and protect the cable from being damaged by external forces and shortening the service life.

Description

technical field [0001] The invention relates to a cable, in particular to an environment-friendly wear-resistant and tensile power cable. Background technique [0002] The tensile and wear resistance of traditional power cables is insufficient, and the sheath on the surface is easily damaged during use. With the development of social economy and science and technology, people have higher and higher requirements on cables, and have strict requirements on the anti-aging performance, tensile resistance and wear resistance of cables, while traditional cables are In terms of performance, it is difficult to meet the existing use requirements, especially for the interface of the main cable and the sub-cable, which is easily disconnected at the interface of the cable when it is dragged and moved or subjected to external wear, and the cable cannot meet the flame-retardant performance and waterproof performance. performance, affecting the normal operation of the power cable.
