[0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer, and is used to transmit electric power or information from one place to another.

[0003] At present, the Chinese utility model with the publication number of CN217035214U discloses a new type of cold-resistant and freeze-proof cable, including a wear-resistant outer sheath and a conductor inner core. The conductor inner core is arranged in the middle inside the wear-resistant outer sheath, and a metal conductor protection layer is connected to the outside of the conductor inner core; an insulating inner sheath is arranged inside the wear-resistant outer sheath on the outside of the metal conductor protection layer, and an anti-freeze component is arranged between the inner wall of the wear-resistant outer sheath and the outer wall of the insulating inner sheath, and an anti-freeze filling layer is arranged between the inner wall of the insulating inner sheath and the surface of the metal conductor protection layer. By setting the cooperation of the anti-freeze filling layer, the inner aluminum foil layer, the heat-insulating cotton layer and the outer aluminum foil layer, when the wear-resistant outer sheath is cracked due to low temperature, the cold-resistant and freeze-proof performance of the cable can be improved through multiple layers of protection. Moreover, by arranging a sliding ring outside the wear-resistant outer sheath, protrusions are arranged on the surface of the sliding ring, and scale lines are arranged on the outer wall of the wear-resistant outer sheath, not only the cable length can be cut more accurately, but also rainwater can be gathered towards the protrusions under the action of gravity to accelerate the dripping of rainwater, so as to reduce the accumulation of water on the surface of the cable.

[0004] To sum up, compared with the above scheme, it cannot improve the heat preservation effect and further enhance the cold-resistant and freeze-proof performance of the cable, and at the same time, it cannot withstand huge impact force and tensile force. For this reason, we provide a cold-resistant and freeze-proof cable structure. Content of the Utility Model

A conductor 2 is sleeved inside the inner sheath 1. An insulating sleeve 3 is sleeved on the surface of the conductor 2. A heat preservation mechanism 4 is arranged inside the inner sheath 1, and a tensile resistance mechanism 5 is arranged inside the inner sheath 1.
