Fire-resistant and flame-retardant cables can maintain circuit integrity in the event of a fire, ensuring the safe and normal operation of critical emergency systems. Currently, they are widely used abroad for fire alarm systems, smoke detection systems, emergency lighting and power systems, and public address systems in buildings such as large shopping malls, hospitals, office buildings, train stations, airports, and residential buildings. Below, we introduce common fire-resistant and flame-retardant power cables and their respective applications.
What are some common fire-resistant and flame-retardant power cables?
1. NH-YJV: Fire-resistant cross-linked polyethylene insulation, PVC sheathed power cable
2. YJV: Cross-linked polyethylene insulation, PVC sheathed power cable
3. ZR-VV: Flame-retardant PVC insulation, PVC sheathed power cable
4. ZR-YJV: Flame-retardant cross-linked polyethylene insulation, PVC sheathed power cable
5. NH-VV: Fire-resistant PVC insulation, PVC sheathed power cable
In what applications are they used?
1. NH-YJV: Fire-resistant cross-linked polyethylene insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, and in pipelines. It can withstand certain traction during installation, but the cable cannot withstand external forces. Single-core cables cannot be installed in pipelines made of magnetic materials. If mechanical resistance is required, steel tape armor should be added.
Suitable for applications with special requirements, such as large-capacity power plants, nuclear power plants, subways, and high-rise buildings.
2. YJV: Cross-linked polyethylene insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, and in pipelines. It can withstand certain traction during installation, but the cable cannot withstand external forces. Single-core cables cannot be installed in pipelines made of magnetic materials. If mechanical resistance is required, steel tape armor should be added.
3. ZR-VV: Flame-retardant PVC insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, cable trenches, pipelines, and in flammable and severely corrosive environments. However, it cannot withstand external forces. If mechanical forces are required, steel tape armor is added.
Features: In the event of an open flame, the fire will automatically extinguish upon removal of the source.
4. ZR-YJV: Flame-retardant XLPE insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, and in pipelines. It can withstand certain traction during installation, but the cable cannot withstand external forces. Single-core cables are not permitted in magnetic pipes. If mechanical forces are required, steel tape armor is added.
Features: In the event of an open flame, the fire will automatically extinguish upon removal of the source.
5. NH-VV: Fire-resistant PVC insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, cable trenches, pipelines, and in flammable and severely corrosive environments. However, it cannot withstand mechanical forces. If mechanical forces are required, steel tape armor is added. Suitable for special applications such as large-capacity power plants, nuclear power plants, subways, and high-rise buildings.
The above is an introduction to the common fire-resistant and flame-retardant power cable models, as well as their usage scenarios. We do not have an absolute statement on the advantages and disadvantages of various models here, and we can consider them according to our actual usage scenarios!
