The invention discloses a cold-resistant and high-temperature resistant power cable which comprises two or more power wire cores, heating wire cores, a flame-retardant filling layer and a fluororubber outer sheath layer, wherein the power cable core is formed by pressing and wrapping a stainless steel wire shielding layer and a silicone rubber insulated layer on two aluminum alloy conductor wire cores from inside to outside; each heating wire core is formed by pressing and wrapping a water-resistant warping tape on a radiating conductor; a tinned wire woven shielding layer is flatly pressed and wrapped on the two or more power cable cores; the upper and lower gaps of every two adjacent power cable cores are respectively provided with a heating wire core; the diagonal positions of the tinned wire woven shielding layer are respectively provided with a ground wire core; the tinned wire woven shielding layer is wrapped by a ceramic insulated warping layer; the flame-retardant filling layer and the fluororubber outer sheath layer are sequentially pressed and wrapped on the ceramic insulated warping layer from inside to outside. The cable is suitable for the low-temperature resistance requirement on a power cable in a low-temperature environment, can work at the temperature between 80 DEG C below zero and 200 DEG C, and the good mechanical performance and strength are provided.
