High-voltage wire harness withstand voltage and temperature rating performance is much higher than the low-voltage harness level, the domestic OEMs usually use shielded high-voltage lines, in recent years, the Japanese mainframe factory mainly uses non-shielded high-voltage wire wrapped outside shielding process. Shielding high-voltage lines can reduce EMI, RFI impact on the entire vehicle system. The entire high-voltage harness circuit is shielded and connected to the high-voltage harness shields of the motor, controller, and battery, and is connected to the battery motor controller housing through a plug-in crimping structure and then connected to the body ground. The shield of the high-voltage line is not necessary for the cable to conduct data, but it can reduce or avoid the radiation of the high-voltage line.
Withstanding voltage performance: Conventional automotive high voltage rated 600V, commercial vehicle and large bus voltage up to 1000 V; current resistance performance: according to the current of the high voltage system components, up to 250 ~ 400A; temperature performance: high temperature rating is divided into 125 °C, 150°C, 200°C, conventional selection of 150°C wire; low temperature routine -40°C
