Abstract

The invention discloses a high-temperature resistance power cable which comprises an H-shaped silicone rubber framework. Two power wire cores are respectively arranged on the two sides of the silicone rubber framework, each power wire core comprises three power conductors wrapped with polyvinyl chloride insulating layers, and after the three power conductors are stranded, an aluminum plastic composite belt taped layer and a glass fiber flame retardant layer wrap the corresponding three stranded power conductors from inside to outside in sequence. The four power wire cores and the silicone rubber framework are stranded to form a cable core, and a taped layer, a mica layer and a sheath layer wrap the cable core in sequence. The H-shaped silicone rubber framework of the high-temperature resistance power cable is ingenious in conception, the silicone rubber framework enhances the firmness of the cable under the condition that the outside diameter of the cable is not increased, and the cable is more resistant to dragging; the framework and sheath are both made of silicon rubber, and fire-resistant performance and high-temperature resistant performance are good.

Description

technical field [0001] The invention mainly relates to the field of cables, in particular to a high temperature resistant power cable. Background technique [0002] Now the environment where power cables are used is becoming more and more diverse. High temperature, low temperature, harsh climate, harsh environment, etc. all pose various problems to the use of conventional cables. The cable of the present invention is aimed at high temperature, which is prone to fire And it is proposed for the environment with high requirements on the firmness of the cable. [0003] Traditional cable sheathing materials have disadvantages such as poor high temperature resistance, poor chemical medium resistance, scratch resistance, and aging resistance. Contents of the invention [0004] The object of the present invention is to provide a high temperature resistant power cable in order to remedy the defects of the prior art. The cable sheathing material of the present invention has good h...
