Smart energy cross-linked polyethylene insulated power cable

The invention discloses a smart energy cross-linked polyethylene insulated power cable, and relates to the technical field of cross-linked polyethylene insulated power cables. The invention provides a smart energy cross-linked polyethylene insulated power cable. The smart energy cross-linked polyethylene insulated power cable sequentially comprises a wire core, an insulating layer, a shielding layer, a wear-resistant layer, a heat preservation and insulation layer and a heat dissipation layer from inside to outside, a heat conduction pipe is mounted between the heat preservation and insulation layer and the heat dissipation layer; a heat insulation piston is mounted in the heat conduction pipe; a metal memory spring is mounted on the inner wall of the heat preservation and insulation layer; the heat insulation piston is connected with the metal memory spring, and the metal memory spring stretches out and draws back to drive the heat insulation piston to move. The metal memory spring can sense the temperature
