High-temperature-resistant anti-cracking power cable

The utility model relates to the technical field of cables, in particular to a high-temperature-resistant anti-cracking power cable, which comprises a frame and a plurality of groups of cable cores, heat insulation columns are filled in a cavity, mounting holes are arranged in the heat insulation columns, cable cores are arranged in the mounting holes, insulating sleeves are sleeved outside the cable cores, and the insulating sleeves are sleeved outside the cable cores. Reinforcing ribs are arranged in the reinforcing holes, an insulating layer is arranged outside the frame in a sleeving mode, a heat insulation layer is arranged outside the insulating layer, a corrosion-resistant layer is arranged outside the heat insulation layer, and heat resistance of the cable is improved by arranging the heat insulation columns and the heat insulation layer; the heat conduction columns are arranged to uniformly disperse the temperature to reduce the influence on the cable when the cable is locally subjected to high tempe
