Descriptions
BBTRZ cable: Flexible mineral insulated fire-resistant cable
BBTRZ cable is a new type of flexible mineral insulated fire-resistant cable. Compared with traditional rigid mineral insulated cables (such as BTTZ), it is more flexible, easier to install and lay, and retains fire resistance performance at the same time.
Applications
BBTRZ cables are widely used in places with high fire protection requirements.
- High-rise buildings: such as office buildings, hotels, shopping malls, etc.
- Public places: such as hospitals, schools, theaters, stadiums, etc.
- Important facilities: such as power plants, substations, petrochemicals, etc
- Fire protection systems: such as fire alarm systems, emergency lighting systems, etc.
Features
- Outstanding fire resistance: It can continuously supply power for more than 3 hours under a 950ºC flame, meeting the BS6387 CWZ grade.
- Good flexibility and easy installation: It adopts stranded conductors and flexible insulating materials, with a small bending radius, which is convenient for laying in narrow Spaces.
- Large current-carrying capacity: Under the same cross-sectional area, the current-carrying capacity is greater than that of ordinary cables.
- Corrosion-resistant and long service life: Made of inorganic materials, it is corrosion-resistant and anti-aging, with a long service life.
- Environmental protection and safety: Low smoke and halogen-free, no toxic gases will be released during combustion.
Construction
| Conductor |
Multi-strand copper stranded wire is adopted, which has good flexibility. |
| Insulation |
High-temperature resistant mineral insulation materials, such as mica tape, are adopted to provide excellent electrical insulation performance and fire resistance. |
| Sheath |
Low smoke zero halogen flame retardant materials, such as polyolefin, are adopted, which have excellent flame retardancy and environmental friendliness. |
Advantages:
- Safe and reliable: Excellent fire resistance ensures continuous power supply in case of fire.
- Easy installation: The flexible structure is convenient for laying and saves installation costs.
- Economic and environmental protection: Long service life, low maintenance cost, and in line with environmental protection requirements.
