Problems solved by technology

[0003] In some areas of northern my country, the working temperature of power cables is generally low, but when the external temperature of power cables is below zero, the cable sheath layer will easily crack due to long-term use after laying and installation, which will affect the normal use of the cables. And reducing the manufacturing cost of cables requires a kind of antifreeze cable and its production method

Abstract

The invention discloses an antifreeze cable, comprising a cable body, wherein the surface of the cable body is provided with an outer protective sleeve, the inside of the outer protective sleeve is provided with an inner protective sleeve, and the outer periphery of the inner protective sleeve is fixedly connected with a foam plastic layer. The invention also provides a production method of an antifreeze cable, in particular comprising the following steps: S1 wire processing, S2 wire wrapping, S3 cable forming process, S4 sheath assembly and S5 cable detection. The antifreeze cable and the production method thereof, compared with that prior art, have low cost, Simple production steps, and well wrap the cable wire through the cooperation of the outer protective sleeve and the inner protective sleeve in the cable body, A foam plastic layer and a glass wool layer are arranged between the outer protective sleeve and the inner protective sleeve can greatly improve the cold-resistant and frost-resistant effect of the cable body, effectively reduce the cracking of the inner protective sleeve, and prolong the service life of the cable in a harsh environment.

Description

technical field [0001] The invention belongs to the field of cables, and more specifically relates to an antifreeze cable, and at the same time, the invention also relates to a production method of the antifreeze cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. [0003] In some areas of northern my country, the working temperature of power cables is generally low, but when the external temperature of power cables is below zero, the cable sheath layer will easily crack due to long-term use after laying and installation, which will affect the normal use of the cables. And reducing the manufacturing cost of the cable requires a freeze-resistan...
