The waterproof layer 33 is made of silicone coating, which has excellent weather resistance and water resistance. It can maintain stability in high humidity and humid environments, thereby ensuring the normal use of the cable. This is a prior art. The inner side wall of the waterproof layer 33 is fixedly connected with a flame retardant layer 34. The flame retardant layer 34 is made of aluminum hydroxide. Aluminum hydroxide is often used as a flame retardant. Since it releases moisture at high temperatures, it has the effect of lowering the temperature. The inner wall of the flame retardant layer 34 is fixedly connected with an endurance layer 35.

[0031] Reference Figure 1-Figure 2The surrounding tube 2 includes a fiber layer 21, the outer wall of the fiber layer 21 is fixedly connected to the inner wall of the plasticized layer 352, the bottom end of the outer wall of the fiber layer 21 is fixedly connected with a tight cladding layer 22, the inner wall of the tight cladding layer 22 is fixedly connected to the outer wall of the fiber core 1, and the fiber layer 21 is made of reinforced aramid. This new material has low density, high strength, good toughness and high temperature resistance, thereby increasing the toughness of the cable as a whole. The material used for the tight cladding layer 22 is silicone material. The material used for the tight cladding layer 22 is silicone material. The silicone material has good bending performance and is not easy to be damaged or cracked. The silicone material has strong adsorption capacity, which is conducive to fixing the position of the fiber core 1 and ensuring the stable transmission work.
