High-Temperature Mica Cable Fire Resistant Mica Insulated Power & Control Cable
High-Temperature Mica Cable is engineered for electrical circuits operating in environments where elevated temperatures and fire resistance are critical. The cable incorporates a high-quality mica tape barrier combined with heat-resistant insulation materials, enabling the conductor to maintain circuit integrity during fire exposure while providing dependable electrical performance under continuous high-temperature conditions.
This cable is widely selected for industrial facilities, emergency power systems, steel plants, tunnels, power stations, petrochemical installations, and other locations requiring enhanced thermal stability and fire survival performance. It is available in single-core and multi-core constructions with various conductor sizes and insulation options to meet different installation requirements.
Key Features

Excellent Fire Survival Capability
The mica insulation layer helps maintain circuit continuity even when exposed to direct flame, supporting emergency systems during fire incidents.
High Temperature Resistance
Designed for continuous operation in elevated ambient temperatures. Depending on insulation materials, operating temperatures can reach 90°C, 105°C, 180°C or higher.
Stable Electrical Performance
High-purity copper conductors provide low resistance, excellent conductivity, and stable current transmission over long service periods.
Outstanding Flame Retardancy
Manufactured to meet common flame-retardant and fire-resistant cable requirements, helping reduce flame propagation in cable installations.
Excellent Mechanical Strength
The cable structure offers good flexibility while maintaining resistance to vibration, installation stress, and mechanical impact.
Long Service Life
Premium insulation materials resist thermal aging, oxidation, and environmental degradation, reducing maintenance requirements throughout the cable's operating life.

FAQ
Q1. What makes mica cable different from ordinary heat-resistant cable?
Mica cable contains an inorganic mica tape layer that can continue providing electrical insulation under direct flame exposure. Ordinary heat-resistant cables mainly withstand elevated temperatures but generally cannot maintain circuit integrity during a fire.
Q2. What temperature can this cable withstand?
The continuous operating temperature depends on the insulation material selected. Standard constructions commonly support 90°C, 105°C, or 180°C, while specialized silicone or ceramic silicone designs can withstand even higher temperatures.
Q3. Is this cable suitable for emergency fire systems?
Yes. High-Temperature Mica Cable is commonly used in emergency lighting, fire alarm circuits, smoke exhaust systems, and other critical power systems requiring fire-resistant performance.
Q4. Can the cable be customized?
Yes. We manufacture customized cables according to customer specifications, including conductor size, core quantity, shielding, armor, insulation material, sheath material, voltage rating, cable color, printing, and packaging.
Q5. Which industries typically use High-Temperature Mica Cable?
It is widely applied in power generation, metallurgy, petrochemical plants, mining, transportation infrastructure, industrial furnaces, manufacturing equipment, and fire protection systems where continuous operation under high temperatures is required.
