Characteristics and application scenarios of fire-resistant and flame-retardant cables

1. NH-YJV: Fire resistant cross-linked polyethylene insulated, polyvinyl chloride sheathed power cable
It can be laid indoors, in tunnels, and in pipelines, and can withstand certain laying traction, but the cable cannot withstand external forces. Single core cables are not allowed to be laid in magnetic material pipelines. If it is necessary to withstand mechanical external forces, steel strip armor should be wrapped around it.
Suitable for special requirements, such as large capacity power plants, nuclear power plants, underground railways, high-rise buildings, etc.
2. YJV: Cross linked polyethylene insulated, polyvinyl chloride sheathed power cable
It can be laid indoors, in tunnels, and in pipelines, and can withstand certain laying traction, but the cable cannot withstand external forces. Single core cables are not allowed to be laid in magnetic material pipelines. If it is necessary to withstand mechanical external forces, steel strip armor should be wrapped around it.
3. ZR-VV: Flame retardant PVC insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, cable trenches, pipelines, flammable and severely corrosive places, but cannot withstand mechanical external forces. If it is necessary to withstand mechanical external forces, steel strip armor should be wrapped around it.
Characteristic: In the case of open flame combustion, remove the fire source and it will automatically extinguish within ≤ 12 seconds.
