UL3239 High Voltage Wire, 24 Awg Silicone Wire | Zhengfeng Wire

UL3239 24AWG wire is a high voltage silicone insulated wire designed for electronic equipment, power systems, medical devices, and industrial applications requiring reliable electrical performance under high voltage conditions.

Manufactured with high quality copper conductor and flexible silicone rubber insulation, this UL3239 high voltage wire provides excellent dielectric strength, heat resistance, flexibility, and long-term stability.

Compared with conventional PVC insulated wires, UL3239 silicone wire offers superior temperature performance, softer handling characteristics, and better resistance against environmental stress, making it suitable for compact equipment where wiring reliability is critical.

The 24AWG size provides a balanced solution between electrical performance and installation flexibility. It is commonly used as a high voltage hook up wire for internal connections in electronic devices, power supplies, transformers, medical equipment, and other high voltage applications.

As a professional UL wire manufacturer, Guangdong Zhengfeng Wire & Cable provides customized UL3239 wire solutions including conductor material, insulation color, voltage requirements, packaging options, and OEM specifications.
