Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to a high-strength tensile-resistant and wear-resistant cable. Background Art

[0002] Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and insulation layers, and are used to connect circuits, electrical appliances, etc.

[0003] However, in the prior art, the cable structure is relatively simple, with only a simple cortex for protection on the outside. Its wear resistance and tensile resistance are poor and it is easy to be damaged, which reduces the service life of the cable and easily causes unnecessary economic losses. For this reason, we propose a high-strength tensile and wear-resistant cable. Utility Model Content
