Wrap EV high-voltage battery & motor wiring

The need: You are building an electric-vehicle high-voltage system and need the orange safety-coloured, heat-resistant, flame-retardant wrap for battery and motor harnesses.

EV high-voltage harnesses use orange as the international warning colour. The wrap must also handle battery/motor heat and meet flame-retardant expectations, so pick an orange cloth tape in a T3–T4 class with UL 94 V-0 / zero-halogen options.

Combine orange high-voltage tape with glass-cloth and flame-retardant grades around the pack.

FAQ

Wrap EV high-voltage battery & motor wiring — questions & answers

Why is EV high-voltage tape orange?

Orange is the globally recognised high-voltage warning colour, so all EV HV harnesses use orange wrap.

Does EV harness tape need to be flame retardant?

High-voltage battery and motor areas typically require flame-retardant, often zero-halogen, tape (UL 94 V-0).
