1, NH-YJV: fire-resistant XLPE insulated, PVC sheathed power cables.

It can be laid in indoor, tunnel and pipeline, and can withstand certain laying traction,

 but the cable can not bear external force, single core cable is not allowed to be laid

 in magnetic material pipe. If you need to bear the mechanical external force, add 

the steel belt to install it.

Suitable for special requirements, such as large capacity power plants, nuclear power

 stations, underground railways, high-rise buildings, etc.

2, YJV: XLPE insulated, PVC sheathed power cables.

It can be laid in the interior, the tunnel and the pipe, which can withstand a certain

 stretch, but the cable can not bear the external force, and the single core cable is

 not allowed to be laid in the magnetic material pipe. If mechanical external force is

 required, steel tape armour is added.

3, the R - V V: flame retardant PVC insulation, PVC sheathed power cables.

It can be laid indoors, tunnels, cable trenches, pipes, inflammable and severely 

corroded places, but it can not bear mechanical external force. If mechanical external 

force is required, steel tape armour is added.

Characteristics: in the case of open flame combustion, remove the fire source,

 less than 12s automatically extinguished.

4, ZR - YJV: flame retardant XLPE insulation, PVC jacket power cable.

It can be laid in indoor, tunnel and pipeline, and can withstand certain laying traction, 

but the cable can not bear external force, single core cable is not allowed to be laid in

 magnetic material pipe. If mechanical external force is required, steel tape armour is added.

Characteristics: in the case of open flame combustion, remove the fire source, 

less than 12s automatically extinguished.

5, N. h. V: fire-resistant PVC insulation, PVC sheathed power cables.

It can be laid indoors, tunnels, cable trenches, pipes, inflammable and severely

 corroded places, but it can not bear mechanical external force. If mechanical 

external force is required, steel tape armour is added. Suitable for special requirements,

 such as large capacity power plants, nuclear power stations, underground railways,

 high-rise buildings, etc.
