Characteristics and applications 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 a certain amount of laying traction, but the cable cannot bear external force. Single-core cables are not allowed to be laid in magnetic material pipelines. If need to bear the mechanical force of steel tape armor.

Suitable for special occasions, such as large capacity power plants, nuclear power plants, underground railways, high-rise buildings, etc.


2. YJV: cross-linked polyethylene insulated and polyvinyl chloride sheathed power cable


It can be laid indoors, in tunnels and in pipelines. It can be laid to a certain extent, but the cables cannot bear external forces. Single-core cables are not allowed to be laid in magnetic material pipelines. If need to bear the mechanical force of steel tape armor.


3, ZR-VV: flame retardant PVC insulation, PVC sheathed power cable


Can be laid in indoor, tunnel, cable trench, pipeline, inflammable and serious corrosion place, but can not withstand external mechanical action. If need to bear the mechanical force of steel tape armor.


Features: In the case of open flame combustion, remove the fire source, ≤12s automatic extinguishment.


4, ZR-YJV: flame retardant crosslinked polyethylene insulation, polychloro-ethylene fuel sheathed power cable


It can be laid indoors, in tunnels and in pipelines, and can withstand a certain amount of laying traction, but the cable cannot bear external force. Single-core cables are not allowed to be laid in magnetic material pipelines. If need to bear the mechanical force of steel tape armor.

Features: In the case of open flame combustion, remove the fire source, ≤12s automatic extinguishment.


5, NH-VV: refractory PVC insulation, PVC sheathed power cable




Can be laid in indoor, tunnel, cable trench, pipeline, inflammable and serious corrosion place, but can not withstand external mechanical action.


If need to bear the mechanical force of steel tape armor. Suitable for special occasions, such as large capacity power plants, nuclear power plants, underground railways, high-rise buildings, etc.
