Fire Resistant Mica Tape Glass Fiber Braided Wire

Engineered for Zero-Failure in High-Heat Environments

When standard heat-resistant cables fail due to insulation embrittlement, CableApex’s fire-resistant mica series provides the ultimate safety margin. Designed for continuous operation at 500°C, this cable is the industry standard for industrial furnaces and smelting equipment.

Multi-Layer Integrity: Our unique construction starts with high-purity Mica Tape helically wrapped around the conductor, providing a primary fire barrier that maintains insulation even if the outer layers are damaged. This is reinforced by a high-density Glass Fiber Braid impregnated with heat-resistant resins for superior mechanical protection.
99.99% Oxygen-Free Copper (OFC): To ensure maximum electrical efficiency, we use only high-grade OFC or Nickel-Plated Copper conductors. This reduces resistance and prevents oxidation at extreme temperatures, extending the service life of your heating systems by up to 30%.
Industrial Durability: The glass fiber outer jacket is engineered to resist fraying and chemical exposure. Whether it’s for kiln wiring, commercial ovens, or heavy-duty smelting leads, our cables undergo 100% dielectric testing at our 20-acre facility to ensure they meet international safety standards.
