UL 3239

What Is UL 3239 Wire?

This high-voltage lead wire (HVLR), UL 3239 wire style, covers single core lead and hook-up wires with a thermoplastic or thermoset insulation suitable for high-voltage direct current (DC) applications. Available DC voltage ratings include anywhere from 10kV to 40kV.

The high-temperature wire uses a thermoset silicone insulation material that's suitable for use to 150 degrees Celsius. Certain UL 3239 style wire allows for DC voltages up to 60 kV and high-temperature applications to 200°C.
