High Temperature Mica Cable for Extreme Heat & Fire Resistant Electrical Wiring

Product Overview

High Temperature Mica Cable is engineered for electrical installations exposed to continuous high heat and emergency fire conditions. Built with a stranded copper conductor wrapped in premium mica tape and reinforced by a fiberglass braid, this cable is capable of maintaining electrical insulation even when exposed to elevated temperatures.

Unlike conventional PVC or XLPE insulated wires, mica insulated cables continue operating where ordinary cables rapidly lose insulation performance. They are commonly installed in industrial heating systems, thermal processing equipment, metallurgy plants, glass manufacturing lines, and emergency power circuits where operational reliability is essential.

Whether used for fixed installations or specialized equipment, this cable delivers dependable performance in demanding industrial environments.

Key Benefits

Outstanding Heat Resistance

The mica insulation system withstands prolonged exposure to high temperatures while minimizing insulation degradation.

Reliable Fire Survival Performance

Mica materials help preserve circuit continuity during fire, making the cable suitable for safety-critical electrical systems.

Excellent Electrical Stability

High-purity stranded copper conductors provide low resistance, stable conductivity, and efficient current transmission.

Durable Mechanical Protection

The fiberglass braid strengthens the cable against vibration, friction, and mechanical wear commonly found in industrial facilities.

Long Operating Life

Designed for continuous service in harsh thermal environments, reducing replacement frequency and maintenance costs.

Custom Manufacturing

Available in various conductor sizes, insulation thicknesses, temperature ratings, and cable constructions according to project specifications.

FAQ

1. What makes mica cable suitable for high-temperature environments?

Mica possesses excellent thermal stability and electrical insulation properties. Even under extreme heat, it continues to provide insulation where many polymer-based materials begin to fail.

2. Can this cable be installed inside industrial furnaces?

Yes. Depending on the exact construction and operating temperature, mica cables are commonly used around furnaces, heating chambers, kilns, and similar equipment. The selected cable specification should match the application's temperature requirements.

3. Is shielding available?

Yes. Copper braid shielding or aluminum foil shielding can be incorporated when electromagnetic interference protection is required.

4. Can you manufacture according to customer drawings?

Certainly. We can produce customized conductor sizes, insulation structures, shielding options, cable colors, and packaging based on technical drawings or project requirements.

5. Which conductor materials are available?

Both bare copper and tinned copper conductors are available depending on environmental conditions and customer requirements.
