Rat-bite-proof high-toughness cable

The invention discloses a rat-bite-proof high-toughness cable, which belongs to the technical field of cables, and comprises a high-toughness cable main body, and the high-toughness cable main body is composed of a heating protection body, an isolation heat insulator, a solid protection body and a metal wire core at the outermost layer; the heating composite body comprises an inner rubber layer and an outer rubber layer, bubble bags are evenly arranged between the inner rubber layer and the outer rubber layer, the isolation heat insulator is composed of a metal shielding layer, a gas inner protection layer, a gas buffer layer and a gas outer protection layer, and repelling gas is injected into the gas buffer layer. According to the cable, the heating protection layer is arranged on the cable, when rodents (rats) damage the cable, colloidal liquid in the bubble bag bodies flows out to make contact with the heating layer composed of quick lime, the lime reacts with water, a large amount of heat is generated, th
