High-Voltage Harness FAQ
We manufacture high-voltage cables rated up to 1000V DC for EV applications and 600V AC for industrial power. Voltage rating depends on the specific cable construction, insulation materials, and application requirements. We can recommend appropriate cables based on your system voltage.
Our HV harnesses include safety features per automotive and industrial standards: orange high-visibility jackets (SAE J1654), HVIL (high-voltage interlock loop) circuits, EMI shielding, touch-safe connector designs, and appropriate current interrupt ratings. Specific features depend on application requirements.
Yes, we manufacture battery pack cables including cell interconnects, module cables, and main pack cables. We work with appropriate HV-rated conductors, insulation, and connectors from manufacturers like TE Connectivity, Amphenol, and others specializing in EV applications.
We offer multiple shielding options: braided copper shields (typically 85-95% coverage), foil shields with drain wire, and combination foil+braid for maximum effectiveness. Shielding selection depends on EMC requirements and frequency range of concern.
