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.

    本申请涉及电缆复合材料技术领域,尤其是一种防冻电缆线及其制备方法。一种防冻电缆线包括橡胶复合外层和位于橡胶复合外层内的导电线束,橡胶复合外层和导电线束之间填充有弹性填充层;所述弹性填充层由若干高弹线材形成;所述导电线束包括若干导电支线,若干导电支线与若干高弹线材绞合、熔融而成带有弹性填充层的导电线束;单根所述导电支线包括多股捻合铜丝芯线和包覆于所述多股捻合铜丝芯线外壁的改性PVC复合保护外层。本申请中提供的防冻电缆线具有良好的低温柔韧性和抗冲击韧性,可在北方严寒地区(‑50℃至80℃)使用,同时兼具良好的阻燃防火安全性能,可改善电缆线的使用安全稳定性能。
