Use description

Inorganic mineral insulated cable is also called flexible fireproof cable. Its conductor is made of multi-strand copper wires, and the insulation layer is made of multi-layer mica tape. The mica tape is made of glass fiber cloth as the base material. Welding closes it to form the outer sheath, and the smooth outer sheath is pressed into a helical shape. Mainly used in offices, hotels, hotels, conference centers and other construction industries: subways, tunnels, light rail, hospitals and other densely populated and underground places: chemical, metallurgical, electric power, high temperature and other industrial and mining enterprises.
