Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a heat-resistant heat-dissipating cable. Background technique [0002] Some high-power cables will generate a lot of heat during the electrification process, which will increase the resistance of the cable and accelerate the aging of the cable, so it is very necessary to dissipate heat from the cable. At present, there are many ways to dissipate heat from cables, among which liquid cooling or structural heat dissipation are two common methods. [0003] Application number CN201620419325.8 discloses a heat-dissipating cable using a precision copper alloy core wire, which uses liquid to absorb heat, distributes the cables to reduce heat concentration, and uses heat dissipation fins to conduct heat and dissipate heat. There are multiple cooling fins on the finned ring, and the multiple cooling fins are distributed around the circumference of the finned ring. The protecti...
