Problems solved by technology

When the cable is used overhead and when it is laid, it will be continuously twisted. Such a twist will cause relative rotation between the twisted body and the sheath layer when the sheath layer and the twisted body are loosely matched. In severe cases, it will affect the power supply. The performance of the cable, and even cause the cable conductor to deform and break

Abstract

The invention belongs to the technical field of cables and electric power and especially relates to an anti-torsion cable. The anti-torsion cable comprises a plurality of insulating wires and a sheath layer covering the insulating wires. Each insulating wire is composed of a conductor and an insulating layer covering the conductor. The anti-torsion cable is characterized in that the adjacent insulating layers are connected through connection ribs, and the sheath layer is in surface contact or double-wire contact with each insulating wire. The anti-torsion cable mainly has the advantages that the anti-torsion performance is good, the number of production devices is fewer, the place used for production is smaller, the manufacturing cost is lower, and the product cost is lower.

Description

[0001] This application is a divisional application of an invention patent application named: A twist-resistant cable, with the application date: July 21, 2014, and the application number: 201410346518.0. technical field [0002] The invention belongs to the technical field of cables and electric power, and in particular relates to a torsion-resistant cable. Background technique [0003] In the prior art, a multi-core cable is usually formed by unidirectional helically twisting a plurality of insulated wires containing insulated core wires inside to form a strand, and then extruding a sheath layer outside the strand; the cable's The stranded body is in the shape of a cylinder, and each insulated wire in the stranded body is tangent to the sheath layer, and each insulated wire forms a single-wire contact with the sheath layer. When the cable is used overhead and when it is laid, it will be continuously twisted. Such a twist will cause relative rotation between the twisted bod...
