A low-temperature-resistant power cable and preparation method thereof

Abstract

A low-temperature-resistant power cable is disclosed, which includes a cable core, cable through pipe and protective tube, the cable core is arranged in the cable through pipe, A protection pipe is arranged on the outside of the cable through pipe, the cable core is composed of a plurality of conductors, one conductor is arranged in the middle, the remaining conductors are arranged in a ring structure around the conductor arranged in the middle, gaps exist among the conductors, and an insulating layer is arranged on the outer side of each conductor, a first insulating layer is arranged on theouter side of the electric wire through pipe, a steel band armor layer is arranged on the outer side of the first insulating layer, a pressure-sensitive structure adhesive tape wraps the periphery ofthe steel band armor layer, and the protective tube is arranged on the outer side of the pressure-sensitive structure adhesive tape. The pipe of the invention has simple structure and good low temperature resistance and strength.

Description

technical field [0001] The invention relates to a power cable, in particular to a low temperature resistant power cable and a preparation method thereof. Background technique [0002] Cables are usually rope-like cables twisted by several wires or groups of wires. Cables are an indispensable part of all aspects of modern national life. With the development of society, wires and cables are more and more widely used in various fields. Although cables have been widely used, there are still some problems. For example, for equipment operating in low temperature environments, conventional cables will lose elasticity, be brittle and cracked, and cannot withstand repeated movements or bending, and conductor leakage will cause safety hazards. , so we need a medium and low temperature resistant cable to solve the above problems and meet people's needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of t...
