“The industry standard for extreme heat environmentsengineered with high-performance PTFE and glass shielding for maximum reliability in temperatures up to 250C.”

Why Professionals Choose TGGT High-Temp Wire

The 4/0 TGGT wire is a massive-capacity feeder cable designed for the most demanding thermal applications. It is the preferred choice for primary power distribution in industrial smelting plants, large-scale commercial ovens, and high-amperage industrial heating systems. By combining 2% Nickel-Coated Copper with high-performance PTFE tapes and a double layer of glass braiding, TGGT provides the ultimate thermal and chemical stability for heavy industrial loads.

• 250C Thermal Performance: Engineered to operate continuously in environments reaching 482F, providing the necessary safety margin for large-scale industrial heating equipment.

• Nickel-Coated Copper Conductor: Features 2% nickel plating per ASTM B355 to maintain high conductivity and prevent conductor embrittlement in extreme heat.

• Triple-Layer Shielding: A combination of PTFE (Teflon) tape, glass yarn, and an outer fiberglass jacket impregnated with a heat-resistant finish.

• Chemical & Oil Resistance: Virtually immune to most industrial solvents, oils, and chemicals, preventing insulation failure in harsh factory conditions.
