In the traditional low-voltage wiring harness market, the demand side is generally stable, and is basically linked to the final vehicle output. The engine wiring harness required for fuel vehicles will be replaced by high-voltage wiring harnesses in new energy vehicles, while other low-voltage wiring harnesses will also be Reduce usage with the penetration of centralized architecture and the need for lightweighting. In terms of high-voltage wiring harnesses, with the improvement of automobile electrification, the driving method of vehicles has undergone fundamental changes. In order to ensure the power output and energy supply of vehicles, high voltage is one of the inevitable solutions. demand is also growing.
