Summary:The utility model relates to the technical field of power cables, and discloses a flame-retardant power cable, which comprises a sheath and a cable core, the cable core is arranged on the inner side of the sheath, and the sheath comprises a first corrosion-resistant layer, a first fireproof layer, a second corrosion-resistant layer, a waterproof layer, an impermeable layer, a thermal insulation layer, a second fireproof layer and a first flame-retardant layer. The first fireproof layer is located on the inner side of the first corrosion-resistant layer, and the second corrosion-resistant layer is located on the inner side of the first fireproof layer. Through cooperative arrangement of the first fireproof layer, the thermal insulation layer, the second fireproof layer, the first flame-retardant layer and the second flame-retardant layer, the flame-retardant effect of the cable can be effectively improved, the cable is prevented from being ignited when short circuit or open fire occurs, and through cooperative
