Mineral insulated cable WD YTTWY Flexible fire-resistant cable
Descriptions
WD YTTWY cable is a flexible fire-resistant cable, whose full name is halogen-free low smoke mineral insulated flexible fire-resistant cable. It is a flexible cable improved on the basis of traditional rigid mineral insulated cables (such as BTTZ cables), featuring excellent fire resistance, high-temperature resistance and electrical performance, and is widely used in places with high fire protection requirements. The following is a detailed introduction to this type of cable from aspects such as structure, features, application fields and advantages.
Applications
- High-rise buildings
It is used for critical power transmission in emergency lighting, fire-fighting equipment, elevators, smoke exhaust systems, etc., to ensure the normal operation of the equipment during a fire.
- Hospital
It is used for power supply in important areas such as operating rooms, icus and emergency rooms to ensure that key medical equipment is not cut off from power in case of fire.
- Subway and Tunnels
It is used for lighting, ventilation, communication and monitoring systems, and is suitable for enclosed and densely populated underground environments.
- Petrochemical Industry
It is used for power transmission in flammable and explosive areas, fire-resistant and high-temperature resistant, and suitable for high-temperature and hazardous environments.
- Nuclear Power Plant
It is used in high-security power transmission systems, fire-resistant and radiation-resistant, ensuring the normal operation of key equipment.
- Large shopping malls and convention centers
It is used in emergency lighting and fire protection systems to ensure the safe evacuation of people in case of fire.
- Airports and railway stations
It is used in lighting, communication, monitoring and fire protection systems, with good fire resistance and suitable for complex wiring environments.
- Data Center:
It is used in power transmission and emergency power supply systems to ensure that the data center does not lose power in case of fire
Features
- Fire resistance performance
It adopts mineral insulating materials, with a fire resistance temperature of over 1000ºC, which can maintain the integrity of the circuit and provide continuous power supply under fire conditions.
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, WD-YTTWY 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.
- 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 |
It adopts multi-strand twisted copper conductors, which have good electrical conductivity, strong flexibility, and are convenient for installation and bending. |
| Insulation |
Mineral compounds (such as mica tape) are used as insulating materials, which are heat-resistant and non-combustible, with a fire resistance temperature of over 1000ºC. |
| Sheath |
It adopts a copper sheath, providing mechanical protection and grounding functions, and also has excellent corrosion resistance. |
| Outter Sheath |
It adopts low smoke and halogen-free materials, which produce less smoke and are non-toxic when burning, meeting the requirements. |
