Mineral insulated cable NG-A(BTLY) Flexible fire-resistant cable
Descriptions
NG-A(BTLY) cable is a kind of mineral insulated fire-resistant cable, fully known as fire-resistant mineral insulated cable. It is a flexible fire-resistant cable improved on the basis of traditional mineral insulated cables (such as BTTZ cables), featuring excellent fire resistance, mechanical and electrical properties, and is widely used in places with extremely high fire protection requirements.
Applications
- High-rise buildings: Emergency lighting and power supply for fire-fighting equipment
- Hospital: Power supply for important areas such as operating rooms and icus.
- Subway and tunnel: Power supply for lighting, ventilation and communication systems
- Petrochemical industry: Power transmission in flammable and explosive areas.
- Nuclear power plant: Power transmission with high safety requirements.
Features
- Excellent fire resistance performance
Mineral compounds (such as magnesium oxide) are used as insulating materials, and the fire resistance temperature can reach over 1000ºC.
It can maintain the integrity of the circuit and provide continuous power supply under fire conditions.
- Flexible structure
Compared with traditional rigid mineral insulated cables (BTTZ), NG-A(BTLY) cables use stranded copper conductors and flexible mineral insulation layers, which are more convenient to install and have better bending performance.
- Heat resistance
It can work for a long time in high-temperature environments and is suitable for high-temperature places.
- Environmental Protection and safety
The outer sheath is made of low smoke and halogen-free materials, generating less smoke during combustion and meeting environmental protection requirements.
- Corrosion resistance
The copper sheath has excellent corrosion resistance and is suitable for damp and corrosive environments.
- High mechanical strength
The copper sheath provides excellent compressive and tensile strength, making it suitable for complex environments.
Construction
| Conductor |
Multi-strand twisted copper conductor with excellent electrical conductivity. |
| Insulation |
Mineral compounds (such as magnesium oxide), heat-resistant and non-flammable.. |
| Inner Sheath |
Copper sheath, providing mechanical protection and grounding functions. |
| Outter Sheath |
