The utility model discloses a cable with cold resistance, comprising cable cores, the number of the cable cores is three, the center of each cable core is provided with a bearing steel cable, the peripheries of the cable cores and the bearing steel cables are provided with hemp rope areas, the outer side of each hemp rope area is provided with a first coating layer, and the outer side of each hemprope area is provided with a second coating layer. A first shielding layer is arranged on the outer side of the first coating layer, a heat insulation layer is arranged on the outer side of the firstshielding layer, cavities are formed in the heat insulation layer at equal intervals, a fixing circular ring is arranged on the outer side of the heat insulation layer, and a second coating layer isarranged on the outer side of the fixing circular ring. According to the utility model, the cavity is arranged and the gas is arranged in the cavity, so that compared with a solid, the thermal conductivity of the gas is lower, and the cold resistance of the cable is greatly improved.
