Abstract
The invention discloses a heat dissipation power cable. The power cable comprises a petal-shaped insulating reinforcement tube formed by splicing four arc frameworks, wherein a round tube is arranged in the inner center of the insulating reinforcement tube, four insulating boards are evenly connected between the outer wall of the round tube and the inner wall of the insulating reinforcement tube, the surfaces of the insulating boards are coated with inorganic heat-absorbing material spray layers, the four insulating boards divide an inner cavity of the insulating reinforcement tube into four small cavities, and cable cores are arranged in the four small cavities and the round tube. The inorganic heat-absorbing material spray layers can release vapor when heated to a certain extent and absorb heat in the vapor release process to play a cooling role and have good high-temperature-resistant and fireproof effects, a crescent-shaped semi-conduction expansion buffer layer is arranged between the cable core in each of the four small cavities and the insulating reinforcing tube, so that the inner structure of the cable is more compact, stable and reliable, and the buffer layers are firm in structure, cannot be crushed and are long in service life.
