“A premier thermal solution for extreme environmentsengineered with mica-glass composite insulation for maximum reliability in temperatures up to 450C.”

Why Professionals Choose MG High-Temp Wire

The 14 AWG MG (Mica-Glass) wire is engineered for the most extreme thermal environments on earth, where even PTFE-based wires (like TGGT) reach their limits. MG wire is the industrial benchmark for internal wiring in industrial kilns, glass plants, cement manufacturing, and heavy-duty smelting equipment. By using a Mica-Glass composite insulation and a 27% Nickel-Coated Copper conductor, it offers structural integrity and electrical safety at temperatures up to 450C.

• 450C Thermal Performance: Rated for continuous operation in environments reaching 842F, providing unmatched safety for extreme-heat industrial zones.

• Mica-Glass Insulation: The mica tapes provide superior dielectric strength and thermal resistance compared to standard plastic or silicone insulators.

• 27% Nickel-Coated Copper: This heavy-duty plating is specifically formulated to prevent conductor oxidation and embrittlement, ensuring a long service life under constant extreme thermal stress.

• Fiberglass Braid Protection: The outer jacket is treated with a high-temperature saturant, providing rugged resistance against abrasion and flame.
