The invention belongs to the technical field of cable manufacturing, and discloses a low-temperature charging cable and a preparation method thereof.The low-temperature charging cable comprises a signal line set, a shielding layer, a plurality of conductors, a non-woven fabric layer and a sheath layer, the signal line set is located in the center, the shielding layer wraps the periphery of the signal line set, the conductors surround the periphery of the shielding layer, and the non-woven fabric layer wraps the periphery of the sheath layer. The outer diameter of the signal line group is small, the bending performance is strong, copper wires in the signal line group and copper wires in the edge conductors are not easy to break, the conductors are arranged on the periphery of the signal line group, namely, the conductors are arranged at the edge positions, the conductors are closer to the external environment, the heat dissipation is faster, the non-woven fabric layer wraps the peripheries of the conductors, and the sheath layer sleeves the periphery of the non-woven fabric layer. The low-temperature charging cable provided by the invention can be rapidly cooled under the condition of large-current charging, does not need regular maintenance, is low in use cost, is small in overall outer diameter, does not break the internal copper wires after being bent for a long time, and is stable in charging performance.

    本发明属于电缆制造技术领域,公开一种低温充电电缆及其制备方法,其中低温充电电缆包括信号线组、屏蔽层、多根导体、无纺布层和护套层,信号线组位于中心位置,屏蔽层包覆在信号线组的外周,多根导线围绕屏蔽层的外周,信号线组外径小,弯折性强,信号线组中的铜线和边缘导体内的铜线不易断裂,导体置于信号线组外周,即将导体设置在边缘位置,导体与外部环境更近,散热更快,无纺布层包覆在多根导体的外周,护套层套设在无纺布层的外周。本发明提供的低温充电电缆,在大电流充电的情况下,能够快速降温,不需要定期维护,使用成本低,整体外径小,长期弯折内部铜丝不会断裂,充电性能稳定。
