Product Features

* Multi-layer fiberglass or mica tape insulation wrapping; mica tape offers excellent high-temperature resistance, combustion resistance, and good insulation properties. Fiberglass is an inorganic fiber with non-flammability, good chemical resistance, low water absorption, high mechanical strength, good insulation, and strong heat resistance.

* During initial commissioning, when the temperature exceeds 200°C, the impregnating varnish may degrade, leaving only pure fiberglass as the insulating material, which can be observed as evaporation.

* Free from hazardous substances, compliant with RoHS standards

Application Scope

* Used in applications where extremely high connection temperatures and ambient temperatures may occur, such as in metallurgy, petroleum, chemical, natural gas, kerosene, and other special environments requiring fire-resistant electrical installations. Examples include steel plants, rolling mills, foundries, glass and ceramic factories, electromechanical equipment, drying tunnels, drying rooms, heating light sources, electric heating appliances, furnaces, and power plant construction, as well as thermoplastic molding processes. Disadvantages include low voltage resistance level and average fire resistance. The cable's special structural design is recommended for a maximum temperature of 220°C in humid environments and for use above this temperature in dry environments.
