Mineral Fireproof Cable
Key words:
Mineral insulated cable is a kind of cable with mineral powder (e.g. magnesium oxide) as insulating material, which is characterized by high fire resistance, high temperature resistance and long service life, and it is suitable for places with high requirements for safety performance.
Product Classification
- Rigid mineral insulated cable (BTTZ): composed of copper conductor, magnesium oxide insulation and copper sheath, it has excellent fire-resistant performance, but the bending performance is poor and the installation is complicated.
- Flexible mineral insulated cable: improved on the basis of rigid structure, using stranded copper conductor and mica tape and other inorganic insulating materials, the outer layer has a metal sheath and plastic outer sheath, with good flexibility and fire resistance, convenient installation. Common models are BTLY, NG-A, BBTRZ, YTTW, etc.
Performance Characteristics
- Fire resistance: mineral insulating materials do not burn at high temperature, can keep power supply in fire, through BS 6387 CWZ and other fire resistance test.
- High temperature resistance: Long-term working temperature can reach 250℃, short-term can withstand high temperature over 1000℃.
- Long life: inorganic material is not easy to aging, the service life is up to 100 years.
- Large flow-carrying capacity: good thermal conductivity, higher flow-carrying capacity than other cables of the same cross-section.
- Waterproof, explosion-proof and corrosion-resistant: seamless metal sheath provides good waterproof, explosion-proof and corrosion-resistant performance.
- High mechanical strength: the metal sheath protects the cable from mechanical damage.
- Environmentally friendly: Halogen free, no toxic gases are produced when burning, in line with environmental requirements.
Application Scenarios
- Fire-fighting system: Provide reliable power supply for fire-fighting equipment to ensure normal operation in case of fire.
- Ultra-high-rise buildings: to ensure the safe operation of the power system, such as the Burj Khalifa in Dubai, Shanghai Center Tower, etc.
- Petrochemical and nuclear power plants: to ensure the uninterrupted operation of equipment in harsh environments.
- Subways and tunnels: Stable transmission of power in confined spaces to prevent accidents caused by failures.
- Industrial field: to meet the needs of high temperature and high power equipment in steel, metallurgy, chemical industry and other industries.
