[0029] The flexible covering layer 8 consists of three layers of flexible materials: the inner layer, the middle layer, and the outer layer of the flexible covering layer 8 are respectively flexible polyvinyl chloride material, polyester elastomer, and flexible polyolefin.

[0030] It should be noted that the inner layer of the flexible sheathing layer 8 is made of flexible polyvinyl chloride, which has good flexibility and insulation properties, and is economical and practical. The middle layer is made of polyester elastomer, which is a low-temperature resistant and highly flexible material that can maintain the flexibility of the cable in cold environments and enhance its tensile and abrasion resistance. The outer layer is made of flexible polyolefin, which has good UV resistance, strong acid and alkali resistance, and good thermal stability.

[0031] Both the first insulating layer 2 and the second insulating layer 6 are made of polyvinyl chloride with added antioxidants, UV stabilizers and antibacterial components, as well as low-smoke halogen-free composite materials.

Antioxidants, UV stabilizers and antibacterial components are added as needed to improve the cable's flame resistance in high-temperature environments. This composite material not only has a good flame retardant effect, but also produces relatively little smoke when burning, avoiding the danger of traditional cables producing a large amount of toxic gases and smoke when burning.
