The invention discloses a power cable. The power cable comprises a plurality of cable cores, wherein each cable core comprises a plurality of cluster wires, the outer layer of each cable core is wrapped with an insulating layer, and the outer layer of the insulating layer is wrapped with a waterproof layer; the cable further comprises a protective sleeve surrounding at least one cable core, and superhard micro-powder is distributed in the protective sleeve; a through hole is formed in an axis, and a reinforcing layer is arranged on the hole wall of the through hole. The power cable disclosed by the invention has the beneficial effects of greatly enhancing the wear resistance of the power cable by placing diamond micro-powder or cubic boron nitride micro-powder in the protective sleeve, improving the service life of the cable, and further improving the waterproof property of the cable by arranging the waterproof layer on each cable core, thereby being suitable for popularization and application.
