Compressive, wear-resistant and anti-corrosion power cable

Abstract

A compression-resistant, wear-resistant and anti-corrosion power cable belongs to the technical field of cables. It includes a cable core, an inner sheath and an outer sheath. It is characterized in that the cable core is twisted by a number of insulated wire cores and shielded wire cores. The shielded wire core is composed of a conductor and an insulating tape wrapped around the conductor; the outside of the cable core is sequentially provided with an insulating shielding layer, a metal sheath layer composed of a corrugated aluminum sheath, and a ceramic The refractory layer made of polyolefin, the inner sheath and the outer sheath are placed on the outer layer of the cable core, and there is an anti-corrosion layer made of asphalt between the two layers. The invention has a simple and reasonable structure and is easy to manufacture. Through the optimization of the structure and the improvement of the material, the cable has the characteristics of tensile resistance, torsion resistance and bending resistance, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to a cable structure, in particular to a pressure-resistant, wear-resistant and anti-corrosion power cable, which belongs to the technical field of cables. Background technique [0002] Large-scale mobile equipment and transmission equipment such as mines and port machinery require strong power support during operation. Due to the very harsh conditions of use of such cables, they often need to be dragged or wound during use, and they must bear large tension, At the same time, due to the complex working environment, exposure to the sun and rain, and frequent smashing, bumping, scraping, grinding, etc. of ore, cargo fragments and sundries, the cable sheath is prone to mechanical damage and scrapped. Therefore, cables are required to have extreme characteristics such as compression resistance, wear resistance, and corrosion resistance. Contents of the invention [0003] The object of the present invention is to provide a pressure-...
