TG 8 high temperature wire is a TGGT wire. TGGT is an acronym which stands for Teflon®-Glass-Glass-Teflon®. Teflon® is a polytetrafluoroethylene (PTFE) originally developed by DuPont. TGGT wire has PTFE tape insulation covered by a high temperature sealant impregnated fiberglass jacket. You can use this wire continuously at 250ºC. In some instances, manufacturers place a ceramic tape on top of the PTFE wire insulation (TCGT).

TG 8 is TGGT wire is a stranded 8 AWG high temperature wire with 113 strands of nickel-plated copper measuring .0111 inch each. This wire conforms to UL 5214 and UL 5256 requirements. It can handle 95 amps and can carry up to 600 volts. It has a nominal inslulation thickness of 0.011 inches and a nominal outer diameter of 0.213. The insulation material is comprised of PTFE tape/fiberglass serving and a fiberglass braid treated with a high-temperature saturant which permits the use of this material in environments where sustained temperatures of 250 degress Celsius may be experienced.
