Power Harness: HDMI USB CAT6 USB-C for Electric Buses

We have developed and produced wiring that keeps the fleets on the road. Our internal wiring harness offerings meet high-voltage demands and deliver dependable performance for electric buses and other heavy-duty vehicles. We use UL-certified cables, strong connectors, and intensive testing to make the service life of our cables long.

We are in the business of Custom Wire Harness Assembly because of New Energy Vehicles. The range of products we offer is Custom Electric Bus Wiring Harness Solutions to New Energy Vehicles and High-Voltage Wiring System to EV New Energy Buses. The HDMI USB CAT6 USB-C Internal Wiring Harness integrates power and data lines, supporting efficient energy transfer and onboard communications.

Product Description

Our Custom Electric Bus Wiring Harness lacks the versatility of a standard wiring harness and it is designed to meet the needs of electric buses. Using high-voltage UL-certified cable assemblies, waterproof and fire-resistant materials, and industry-standard connectors (TE, Molex, JST, Delphi, Sumitomo, Yazaki),  ensures safe power distribution, integrated BMS connectivity, and flexible routing for interior systems.

We manufacture high-performance drive train cable sets that are heavy-duty and modular assemblies that are retrofit-friendly.
