1.Product Overview
The BBTRZ flexible mineral insulated cable represents the next generation of fire safety technology, specifically engineered to safeguard critical power and control circuits. Utilizing a high-purity copper conductor and an advanced inorganic mineral compound insulation, this BBTRZ fire-proof cable is designed to maintain electrical function during extreme thermal events. As a premium circuit integrity fire survival cable, it eliminates the need for rigid metal tubing, offering a more compact and flexible installation. Furthermore, its low smoke halogen-free power cable construction ensures that toxic emissions are minimized, providing a safer environment for evacuation and rescue operations in high-occupancy buildings.
2.Core Product Advantages
Exceptional Fire Survival Performance: Engineered with fully inorganic materials, the BBTRZ cable is designed to maintain circuit integrity even under intense fire conditions. It meets the rigorous requirements of international standards such as BS 6387 and IEC 60331 (subject to specific test reports).
Space-Saving Flexibility: Unlike traditional rigid MI cables, the BBTRZ features a flexible, multi-core arrangement that allows for easier routing in tight architectural spaces and complex cable trays, significantly reducing installation time and costs.
Safety-First LSZH Construction: The halogen-free outer jacket ensures low smoke density and zero halogen gas emissions during a fire. This feature is critical for maintaining visibility and preventing corrosive damage to sensitive electronic equipment.
Robust Mechanical Integrity: Despite its flexibility, the cable is designed with a compact, high-density mineral compound sheath that provides reliable protection against mechanical impact and crushing.
