Mineral-insulated flexible fire-resistant cable

BBTRZ mineral-insulated flexible fire-resistant cable features twisted copper conductors, an inorganic mica tape as the fireproof layer, and a mineral compound used as an oxygen-barrier filler—all crafted with advanced manufacturing techniques. Additionally, the outer layer is coated with an inorganic material that remains non-melting and non-flammable even under intense flame exposure, ensuring superior protection. This cable is ideal for installation in high-risk, densely populated areas and critical facilities requiring maximum safety, such as tunnels, cable trays, cable trenches, junction boxes, shafts, high-rise buildings, subways, shopping malls, hospitals, schools, hotels, museums, railway stations, public entertainment venues, and data centers—where reliable power distribution and transmission are essential.
