BBTRZ Fireproof Flexible Mineral Insulated Power Cable

BBTRZ Fireproof Flexible Mineral Insulated Power Cable

BBTRZ flexible mineral insulated power cable with excellent fire resistance, ideal for fire protection wiring of high-rise and public buildings.

BBTRZ is a flexible fire-resistant mineral insulated power cable. It uses soft copper conductors, breaking the rigid limitation of traditional mineral cables.
Special mineral insulation delivers outstanding fire resistance. It can keep power supply intact under long-time high-temperature burning.
The cable structure is bendable for convenient laying in narrow pipe shafts and complex building layouts. It also features smoke-free, halogen-free performance to improve evacuation safety during fires.
Multiple cross-section options fit emergency lighting, fire pump and fire control power circuits of all kinds of buildings.
