High-voltage harnesses for EV traction, BESS, charging infrastructure, and industrial power. Orange jacket, XLPE insulation, HVIL loop wiring, and 100% dielectric test before every shipment.

A high-voltage harness that fails in an EV traction system or a BESS rack does not generate a warranty claim — it generates a safety incident. Every material, termination, and test parameter must be traceable to a voltage and temperature rating before the first unit ships. Orange jacket is a visual indicator, not an insulation rating. XLPE insulation at 1000V is the real protection, and the hipot test is the only way to verify it at the assembly level.
If your application is also waterproof, see waterproof harness — we stack IP sealing and HV insulation in a single build. For sealed high-current battery cables with lugged terminations, see power & battery cables. For the baseline custom harness without HV requirements, see custom wire harness.
