UL 3135 Wire 20awg Silicone Rubber Insulated Wire
The 30 AWG UL1332 Teflon Insulated Wire is a UL-certified hook-up wire designed for internal wiring of electrical and electronic equipment. It features a finely stranded copper conductor for flexibility and a high-performance Teflon (PTFE) insulation that ensures excellent thermal, chemical, and electrical resistance.Being UL1332 rated, this wire meets UL758 standards, guaranteeing flame retardancy, dielectric strength, and long-term reliability. Its 30 AWG size (approx. 0.255 mm diameter) makes it ideal for compact, space-limited applications, especially where precision wiring is required.
