[0029] The braided layer 2 can provide the cable with additional mechanical strength and tensile strength, protecting the conductor 1 inside the cable from damage by the external environment. The outer sheath 8 of the cable is the outermost protective structure. The outer sheath 8 is usually made of wear-resistant and corrosion-resistant polyvinyl chloride material. This material has excellent wear resistance and chemical stability. Even in harsh working environments, it can effectively protect the internal cable structure from damage. The wear resistance of polyvinyl chloride makes it difficult for the cable to wear or break when it is subjected to external friction, thereby extending the service life of the cable. At the same time, its corrosion resistance also enables the cable to maintain stable performance in harsh environments such as humidity, acid and alkali. In addition to the outer sheath 8, the cable also has a resistant The multi-layer protective structure of the cable is a wear layer 7, a heat insulation layer 6 and a silicone rubber insulation layer 5. The wear layer 7 is usually made of polyethylene material. This material has strong chemical corrosion resistance, which further enhances the wear resistance of the cable and makes it more durable when subjected to external forces. The heat insulation layer 6 is made of glass fiber insulation material. Glass fiber is an insulating material with good heat insulation performance, which can effectively reduce the conduction and propagation of heat. In addition, glass fiber also has a high melting point and thermal stability, and can maintain stable physical properties under high temperature conditions, thereby ensuring the stable operation of the cable under high temperature conditions. The silicone rubber insulation layer 5 is the core part of the cable, which is made of silicone rubber material. Silicone rubber has excellent high temperature resistance and can maintain stable insulation performance at temperatures as high as 200°C or higher. At the same time, silicone rubber also has excellent weather resistance and aging resistance, can maintain stable performance for a long time, and is not easily affected by external environments such as ultraviolet rays, oxygen, and moisture.

[0030] Working principle: When the cable needs to be used, the outer sheath 8 is used as the outer layer of the entire cable to protect the internal cable structure from mechanical and environmental damage. The outer sheath 8 is usually made of wear-resistant and corrosion-resistant polyvinyl chloride material, thereby achieving the effect of safe operation of the cable under harsh working conditions. The wear-resistant layer 7 is made of polyethylene material, and polyethylene has strong resistance to chemical corrosion, thereby increasing the wear resistance of the cable and extending its service life.

It can effectively reduce the conduction and propagation of heat. At the same time, it has a high melting point and thermal stability. It can maintain stable physical properties in high temperature environments and can maintain the stability of the cable under high temperature conditions. The silicone rubber insulation layer 5 is made of silicone rubber material. Silicone rubber has excellent high temperature resistance and can maintain stable insulation performance in high temperature environments. It can usually withstand temperatures up to 200°C or higher. At the same time, it has excellent weather resistance and aging resistance, can maintain stable performance for a long time, and is not easily affected by external environments such as ultraviolet rays, oxygen, and moisture, thereby improving the high temperature resistance of the cable.
