High-strength, low-temperature and wear-resistant power cable

Abstract

The invention discloses a high-strength, low-temperature and wear-resistant power cable which mainly comprises three aluminum alloy conductor cable cores, a polyester fiber layer, an aluminum copper clad armor layer, a neoprene sheath layer, an ethylene propylene rubber insulating layer and a steel tape armor polyolefin sheath layer, wherein the three aluminum alloy conductor cable cores are twisted together; the polyester fiber layer is wrapped outside the three aluminum alloy conductor cable cores; the aluminum copper clad armor layer is wrapped outside the polyester fiber layer; the steel tape armor polyolefin sheath layer is arranged on an outermost layer; and sixteen copper conductors are extruded in outer clad layers of the cable cores. The cable has the characteristics of high rigidity, wear resistance, high strength, high thermal stability, innocuity, radiation resistance, flame retardance and the like, and can keep an excellent mechanical property at a freezing air temperature in the north.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a high-strength low-temperature wear-resistant power cable. Background technique [0002] At present, in the northern regions of my country, especially in the northeast region, the temperature will drop to tens of degrees below zero in winter. In this environment, the construction period of ordinary power cables is short during construction, and the outer sheath of the cable becomes brittle and easy to crack. , bending performance weakening and many other disadvantages, forced construction is likely to cause huge waste of raw materials and potential safety hazards. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a high-strength low-temperature wear-resistant power cable. [0004] The present invention is achieved by adopting the following technical solutions: a high-strength low-temperature wear-resistant...
