GN500 Ultra-High Temperature Industrial Furnace Wire (500°C)

In diverse industrial settings, having a versatile cable that balances extreme heat resistance with long-term durability is essential for reducing maintenance costs. CableApex offers a high-performance GN500 Ultra-High Temperature Industrial Furnace Wire (500°C)We use premium grade Phlogopite Mica to ensure stable insulation at 500°C.

The Ultimate Performance for Extreme Thermal Environments

When the temperature exceeds the limits of silicone or Teflon, CableApex’s GN500 series stands alone. Specifically designed for the internal wiring of industrial furnaces, smelting equipment, and aerospace testing rigs, this cable thrives where others fail.

Advanced Nickel-Plated Copper Conductor: Standard copper oxidizes rapidly at 500°C. Our GN500 wire features a thick Nickel-Plating over a high-purity copper core, or optional Pure Nickel conductors. This prevents embrittlement and maintains low electrical resistance during long-term exposure to extreme heat.
Dual-Layer Mineral Insulation: The core is protected by high-purity Mica Tape wrapping, followed by a secondary layer of high-density Glass Fiber Braiding impregnated with heat-resistant silicone resin. This multi-barrier system ensures dielectric integrity even if the outer jacket is exposed to direct flame or mechanical stress.
15 Years of Specialized Manufacturing: Produced in our 20-acre facility in Yangzhou, every batch of GN500 wire undergoes a 500°C soak test and high-voltage spark testing. We understand that in metallurgy and heavy industry, a single cable failure can lead to massive downtime.

Why Choose Our 500°C Rated Electrical Cable?

Not every application requires specialized furnace wire, but many demand more than standard insulation. Our 500°C cable fills this gap, providing a robust solution for:

Versatile Thermal Protection: Features premium mica tape and reinforced fiberglass braiding, ensuring the cable remains flexible yet heat-stable.
Long-Term Reliability: Unlike lower-grade wires that become brittle over time, our high-purity conductors (nickel-plated or tinned copper) maintain excellent electrical conductivity under constant thermal stress.
Cost-Efficient Inventory: Its “general purpose” nature makes it an ideal stock item for facilities managing multiple high-heat zones, from drying rooms to chemical processing lines.
