Copper High Temperature Mica Cable Fire Resistant Mica Insulated Copper Wire

High-Temperature Mica Cable – Fire Resistant Mica Insulated Copper Wire

High-Temperature Mica Cable is designed for electrical systems that must continue operating under extreme heat conditions. The cable uses mica tape insulation combined with copper conductors and a heat-resistant outer layer, providing reliable electrical performance at elevated temperatures. It is widely used in industrial furnaces, heating equipment, metallurgy, glass manufacturing, power plants, and other high-temperature environments where conventional cables may fail.

This type of cable is valued for its excellent fire resistance, thermal stability, and insulation performance. Even when exposed to direct flame for a certain period, the mica insulation helps maintain circuit integrity, making it suitable for emergency power, fire protection systems, and critical industrial applications.

  FAQ

  1.What is the maximum temperature this cable can withstand?

  The operating temperature depends on the cable design. Common models can work continuously at 250°C to 450°C, while some special constructions can withstand even higher temperatures for short periods.

  2.Can this cable be used in fire protection systems?

  Yes. Mica insulated cables are widely used in fire alarm systems, emergency power circuits, and other applications that require circuit integrity during a fire.

  3.Is the cable suitable for outdoor installation?

  Standard fiberglass braided types are mainly used indoors or in protected environments. For outdoor installation, a weather-resistant outer sheath can be added based on project requirements.

  4.Can conductor size and voltage rating be customized?

  Yes. The cable can be customized according to conductor cross-section, number of cores, voltage rating, temperature class, and application requirements.
