Problems solved by technology
[0002] At present, many wires and cables will generate too much heat during use, which will cause the cable to soften. After long-term use, the wind and the sun will make the outer layer of the cable insulation aging, and finally crack or even fall off, which will affect the safety of the cable. In addition, due to the aging and cracking of the insulation layer, the strength of the cable is reduced, and the cable may also be brittle.

Abstract
The invention discloses a heatproof high-strength cable, comprising conductors, insulating films wrapped outside each conductor, and a high temperature resistance insulating layer wrapping outside the three stacked conductors. The conductor is stranded by a plurality of silver-plated round copper wires. The number of the conductors is three, and the conductors are stacked in a shape of a Chinese character pin. The insulating film is made of polyvinyl chloride. The high temperature resistance insulating layer is made of silicone rubber. The silicone rubber is prepared by mixing methyl vinyl silicone rubber, carbon black, hydroxyl silicone oil, and dibenzyl silanediol, and is processed by sulfidizing. A rubber sheath wraps on the periphery of the high temperature resistance insulating layer, and the rubber sheath is processed by the sulfidizing. Because of arrangement of the rubber sheath and the high temperature resistance insulating layer which are processed by the sulfidizing, the cable has relatively high temperature resistance performance, and the three conductors are stacked in the shape of the Chinese character pin, strength of the cable is greatly improved, thereby greatly improving service life of the cable.
Description
technical field [0001] The invention relates to the technical field of wires and cables, in particular to a heat-resistant high-strength cable. Background technique [0002] At present, many wires and cables will generate too much heat during use, which will cause the cable to soften. After long-term use, the wind and the sun will make the outer layer of the cable insulation aging, and finally crack or even fall off, which will affect the safety of the cable. Performance; In addition, due to the aging and cracking of the insulation layer, the strength of the cable is reduced, and the cable may also be brittle. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a heat-resistant high-strength cable, which can withstand higher temperatures, is not easy to age, and has relatively high strength. [0004] A heat-resistant high-strength cable proposed by the present invention includes a conduct...
