Fireproof High Temperature Mica Insulated Wire For Industrial Heating Furnace Applications

High-Temperature Mica Cable for Industrial Heating & Furnace Applications

High-temperature mica cable is a fire-resistant electrical cable designed for applications where continuous operation at elevated temperatures is required. The cable uses mica tape insulation combined with high-temperature fiberglass braiding and stranded copper conductors to maintain circuit integrity during heat exposure.

This type of cable is widely used in industrial furnaces, heating equipment, steel plants, power generation systems, fire-resistant circuits, and other environments where conventional PVC-insulated cables cannot operate reliably.

Product Features

• Excellent heat resistance: Suitable for continuous operation in high-temperature environments.

• Fire-resistant performance: Mica insulation helps maintain electrical continuity during fire exposure.

• Copper conductor: Provides stable electrical conductivity and mechanical flexibility.

• Fiberglass braided insulation: Offers additional thermal protection and mechanical strength.

• Low smoke characteristics: Produces less smoke than many standard polymer-insulated cables.

• Good durability: Resistant to thermal aging, abrasion, and vibration in industrial environments.
