EV cables as a bridge connecting the pile and the vehicle, the EV cable is very important. Except for the outdoor performance of the basic cable such as insulation and flame retardant, the overall hardness of the cable should not be too high, because it should be bent frequently. The so-called EV cable material generally refers to an elastomer-related material for the insulating layer and the sheath layer. Material properties require oil resistance, tear resistance, weather resistance, chemical resistance, high-temperature resistance and softness. At present, the more mainstream ones are TPU, TPE, PVC elastomer, etc.
