MG - 450°C | 550°C

MG Wire, or Mica Glass Wire, is a specialized high-temperature electrical wire designed for extreme heat environments. It typically features stranded nickel-plated copper conductors, mica tape insulation, and an outer fiberglass braid. Rated for 450°C (842°F) and sometimes higher, up to 550°C (1022°F), and generally for 300V or 600V, it is used in applications where standard wires cannot perform.

MG Wire stands out due to its mineral-based insulation system, primarily mica tape and a fiberglass braid, which enables it to withstand continuous operating temperatures up to 450°C and even 550°C for specialized versions. Unlike wires with polymer-based insulation like PTFE (Teflon), which typically max out around 250°C, MG wire's non-combustible materials will not melt, burn, or become brittle in extreme dry heat, ensuring insulation integrity and superior thermal stability.

MG Wire is essential for "hot spot" applications where internal operating temperatures exceed 250°C. Common uses include:

• Industrial Ovens, Furnaces, and Kilns: Internal wiring for commercial drying equipment, heat-treating furnaces, and ceramic/glass kilns.
• Commercial Cooking Equipment: Internal connections for high-wattage appliances like pizza ovens and deep fryers.
• Control Panels: Wiring near boilers, steam generators, and process heaters where ambient temperatures are high.
• Foundries and Steel Mills: Power and control wiring exposed to radiant heat sources and molten metal.

MG Wire is engineered with layers of non-combustible material for maximum thermal stability. Its construction includes:

• Conductor: Finely stranded, nickel-plated copper, which prevents oxidation and maintains resistance at high temperatures.
• Insulation: Flexible mica tape or a mica composite, providing primary electrical insulation and exceptional thermal stability.
• Outer Braid: A high-strength fiberglass braid, often treated with a high-temperature saturant, for mechanical protection, abrasion resistance, and enhanced flame resistance.

MG Wire is primarily designed for continuous operation at extreme temperatures.

• Temperature Rating: Commonly rated for 450°C (842°F), with specialized versions, such as Duraflex MG Wire, rated up to 550°C (1022°F) for continuous operation or short-term exposure.
• Voltage Rating: Typically rated for 300V or 600V, making it suitable for standard industrial heating and control circuits.
