The invention relates to the technical field of cable composite materials, in particular to an anti-freezing cable and a preparation method thereof. The anti-freezing cable comprises a rubber composite outer layer and a conductive wire harness positioned in the rubber composite outer layer, wherein an elastic filling layer is filled between the rubber composite outer layer and the conductive wire harness; the elastic filling layer is formed by a plurality of high-elasticity wires; the conductive wire harness comprises a plurality of conductive branch wires, and the plurality of conductive branch wires and a plurality of high-elasticity wires are twisted and fused to form the conductive wire harness with an elastic filling layer. Each conductive branch wire comprises a plurality of twisted copper wire core wires and a modified PVC composite protection outer layer wrapping the outer wall of the plurality of twisted copper wire core wires. The anti-freezing cable provided by the invention has good low-temperature flexibility and impact toughness, can be used in northern severe cold regions (-50 DEG C to 80 DEG C), has good flame-retardant and fireproof safety performance, and can improve the use safety and stability of the cable.
