Product Description
This product is suitable for power transmission in power lines with a rated voltage of 0.6/1KV and below. Flame-retardant wires and cables are difficult to catch fire and have the ability to prevent or delay the spread of flames. They are used for laying in a variety of occasions where the cable has flame-retardant requirements, such as high-rise buildings, hotels, hospitals, subways, nuclear power plants, power plants, ore, and petroleum. , Chemical industry, etc.
Main technical characteristics and advantages
- Rated voltage: 0.6/1kV
- Maximum continuous operating temperature: 90℃
- Maximum short circuit temperature(maximum duration 5s): 250℃
- Minimum bending radius of cable: 15×O.D.(multi-core), 20×O.D.(single core)
- Fire resistant characteristic: GB/T 19216 (750℃/90min.), BS6387 (resistance to fire alone 650/180min., resistance to fire with water 650/15min, resistance to fire with mechanical shock 950/180min) .
- Excellent low smoke halogen free: Acc. to GB/T17650/IEC60754, GB/T17651/IEC61034. special cable construction design with inorganic mineral insulation and copper sheath, no smoke and no toxic release during combustion, cannot make the second hazards to equipment and personal safety.
- Well flexibility, easy for installation and suitable for long length packing and delivery.
- Better economy: corrugated copper sheath design can be installed directly without cable bridge, easy for installation and has lower installation cost.
- Good shield performance with corrugated copper sheath design.

Application
Flexible mineral insulated fireproof cable BBTRZ, also known as flexible mineral insulated fireproof cable, means that it can maintain normal energization without breakdown through 180K of 1KV voltage in 950 °C flame high temperature environment. It is a modified model of BTTZ mineral insulated cable and inherits BTTZ rigid mineral insulated cable. In addition to fireproof, explosion-proof, temperature-resistant, large current-carrying capacity, etc., it is not easy to absorb moisture. The insulation performance is more stable. It can be multi-core, fixed-length production, flexible structure, easy to bend, no need for special cable terminal joints and intermediate connectors, suitable for each The laying method can be laid according to the conventional cable.
