UL3239 18AWG High Voltage Silicone Wire for Power Systems

UL3239 18AWG wire is a high voltage silicone insulated cable designed for electrical systems that require enhanced insulation protection, stable performance, and reliable power transmission.

Featuring a flexible stranded copper conductor and durable silicone rubber insulation, this 18AWG high voltage wire provides excellent electrical safety, mechanical flexibility, and resistance to heat aging.

Compared with smaller gauge high voltage wires, UL3239 18AWG offers a larger conductor size, making it suitable for applications requiring higher current capacity while maintaining excellent flexibility and installation convenience.

The silicone insulation structure helps protect the conductor in demanding environments including industrial equipment, electronic power systems, medical instruments, and high voltage assemblies.

As an experienced UL3239 wire manufacturer, Guangdong Zhengfeng Wire&Cable provides customized solutions including conductor material, insulation color, voltage requirements, printing, and packaging according to customer specifications.
