Fiberglass cable is a high-temperature resistant electrical cable designed for use in extreme thermal and harsh industrial environments. It features a conductor insulated with fiberglass yarn or braid, often impregnated with heat-resistant varnish or silicone for added protection. Fiberglass cables can withstand temperatures ranging from 250°C to 400°C, depending on construction, making them ideal for furnaces, ovens, heaters, and metallurgical applications. They offer excellent resistance to heat, flame, chemicals, and mechanical abrasion. Fiberglass cables also provide good electrical insulation and long service life. Due to their durability and thermal stability, fiberglass cables are widely used in power plants, steel industries, and high-temperature industrial equipment.
