With the rapid development of the new energy vehicle market, increasing attention is being paid to the safety and reliability of high-voltage wiring harnesses, one of the key components of new energy vehicles. High-voltage wiring harnesses are critical components that connect charging systems, power batteries, motors, inverters, and other equipment in new energy vehicles. They are responsible for transmitting high-voltage, high-power electrical energy while shielding against external signal interference. The quality of their connections and routing is one of the key factors affecting the safe operation of electric vehicles.

High-voltage wiring harnesses in new energy vehicles need to withstand voltages ranging from 300 V to over 1000 V. They are responsible for power transmission and distribution while connecting all high-voltage electronic components, making them the “neural network” of the vehicle’s high-voltage system. Therefore, dedicated high-voltage wiring harnesses capable of withstanding high voltages are required to safely transmit electrical energy. High-voltage systems require wiring harnesses to have superior insulation performance and voltage withstand capability to prevent electrical failures.
