[0031] Referring to Figure 2 In some embodiments of the utility model, the cable includes cable body 100, cable body 100 includes cable core 110, first fireproof layer 120 and first high temperature resistant layer 130, first fireproof layer 120 and first high temperature resistant layer 130 are covered in turn on the outside of cable core 110, cable core 110 includes conductor 111, second fireproof layer 112 and first insulating layer 113, second fireproof layer 112 and first insulating layer 113 are covered in turn on the outside of conductor 111. The cable of the application can have good high temperature resistance and fire resistance.

[0032] Need to explain, referring to Figure 2 , first high temperature resistant layer 130 is covered on the outside of cable core 110, and first fireproof layer 120 is covered on the outside of first high temperature resistant layer 130. Covering first fireproof layer 120 on the outside of first high temperature resistant layer 130 can further improve the fireproof performance of cable body 100, and the internal cable core 110 is not easily penetrated by flame in fire, to ensure stable work. The outside of cable core 110 is covered with first high temperature resistant layer 130, and the physical and chemical properties of first high temperature resistant layer 130 are stable in high temperature environment such as fire, to protect the internal cable core 110.

[0033] Among them, first high temperature resistant layer 130 can be made of glass fiber material or ceramic fiber material, which can effectively improve the temperature resistance of cable body 100. Alternatively, first high temperature resistant layer 130 can also be made of high temperature resistant organic polymer material, such as polytetrafluoroethylene (PTFE), silicone rubber, etc. The person skilled in the art can be determined according to the actual situation, which is not limited here.

[0034] First fireproof layer 120 can be made of phlogopite material, which mainly improves the fire resistance of the cable, and the fire resistance temperature can reach about 1000 DEG C. For example, first fireproof layer 120 is impregnated with thin phlogopite paper and specific high temperature adhesive, and is reinforced on the outside with glass cloth, so as to have high electrical insulation and heat resistance (up to 1000 DEG C), so that when the cable contacts the flame, the mica can still maintain its electrical insulation at high temperature. Alternatively, first fireproof layer 120 can also be made of fire-resistant polyvinyl chloride (PVC) or crosslinked polyethylene (XLPE) material, and the person skilled in the art can determine according to the actual situation, which is not limited here.

[0036] The second fireproof layer 112 can also be wrapped with phlogopite material to improve the fireproof performance of the cable, and the fireproof temperature can reach about 1000 DEG C. For example, the first fireproof layer 120 is impregnated with thin phlogopite paper and a specific high-temperature adhesive, and is reinforced on the outside with glass cloth, thereby having high electrical insulation and heat resistance (up to 1000 DEG C), so that the cable can still maintain its electrical insulation at high temperatures when it contacts the flame. Alternatively, the first fireproof layer 120 can also be made of fireproof polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE) material, and the person skilled in the art can determine it according to the actual situation, which is not specifically limited here.

[0038] The first insulating layer 113 can be made of an elastomeric insulating material by an extrusion process, and the first insulating layer 113 also has excellent high-temperature resistance and softness, as well as environmental protection, halogen-free and low-smoke characteristics.
