[0026] The present scheme has the following working process:

[0027] When the cable is used in a high-latitude cold region, the cable needs to be protected to prevent damage and frost cracking, therefore, the cable used in a cold environment needs to be wrapped with the insulation layer 2 first, so that the wire 1 will not be subject to electric leakage, and then the plurality of insulation layers 2 are accommodated in the protective layer 3 to protect the wire 1 and the insulation layer 2, heat generated during the use of the wire 1 can enter the thermal insulation layer 6 and the protective layer 3 through the heat conduction cavity 4, the outer shell layer 7 outside the thermal insulation layer 6 plays a protective role to prevent damage and affect the use of the cable, the outermost water absorption layer 8 can absorb rain and snow and freeze in a cold environment, avoiding the contact between rain and snow and the outer shell layer 7, and the anti-sticking block 9 prevents the water absorption layer 8 from sticking to the outer shell layer 7.

[0028] According to the above working process, it can be known that:

[0029] The water absorption layer 8 absorbs water to prevent rain and snow from contacting the outer shell layer 7 and rapidly reducing the heat inside the outer shell layer 7, the heat generated during the use of the wire 1 can enter the thermal insulation layer 6 and the protective layer 3 through the heat conduction cavity 4, so that the heat can be better protected, preventing external damage caused by the high central temperature and the low external temperature.

[0030] Further, the insulating layer 2 is made of polyvinyl chloride material, and the protective layer 3 is made of cross-linked polyethylene material. Specifically, polyvinyl chloride is a commonly used plastic material, usually white or light yellow powder in appearance.
