Inorganic mineral insulated cable, also known as flexible fireproof cable, its conductor is made of stranded copper wires, with multi-layer mica tape as insulating layer, mica tape is made of glass fiber cloth as base material, and the outer layer is longitudinally wrapped and welded with copper tape. It is closed to form an outer sheath, and the smooth outer sheath is pressed into a spiral shape. It is mainly used in construction industries such as offices, hotels, hotels, conference centers, subways, highways, light rails, hospitals and other densely populated and underground places, and industrial and mining enterprises such as chemical, metallurgy, electric power, and high temperature.BBTRZ Flexible Mineral Insulated Fireproof Cable. The cable conductor is made of stranded copper wires with good bending properties. The insulating layer is made of mineral insulating material, which can withstand temperature above 1000 degrees. The waterproof isolation layer uses polyethylene isolation material.
