1, VV: PVC insulated, PVC sheathed power cable

Can be laid indoors, tunnels, cable trenches, pipelines, flammable and severely corroded, but can not withstand mechanical external forces. It is necessary to bear the external force of the machine and add the steel tape armor.

2, YJV: XLPE insulated, PVC sheathed power cable

It can be laid indoors, in tunnels and in pipes, and can withstand certain laying and pulling, but the cable can not bear external force, and single-core cable is not allowed to be laid in the magnetic material pipeline. It is necessary to bear the external force of the machine and add the steel tape armor.

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

Can be laid indoors, tunnels, cable trenches, pipelines, flammable and severely corroded, but can not withstand mechanical external forces. It is necessary to bear the external force of the machine and add the steel tape armor.

Features: In the case of open flame burning, remove the fire source, ≤ 12s automatically extinguished.

4, ZR-YJV: flame retardant XLPE insulated, PVC flame sheathed power cable

It can be laid indoors, in tunnels and in pipelines, and can withstand certain laying traction, but the cable can not bear external force, and single-core cable is not allowed to be laid in magnetic material pipeline. It is necessary to withstand the action of mechanical external force and to wrap around the steel belt.

Features: In the case of open flame burning, remove the fire source, ≤ 12s automatically extinguished.

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

Can be laid indoors, tunnels, cable trenches, pipelines, flammable and severely corroded, but can not withstand mechanical external forces. It is necessary to bear the external force of the machine and add the steel tape armor. Suitable for special requirements, such as large-capacity power plants, nuclear power plants, underground railways, high-rise buildings, etc.

Features: Protects the normal operation for 90min (minutes) in a burning environment.

6, NH-YJV: refractory XLPE insulated, PVC sheathed power cable

It can be laid indoors, in tunnels and in pipelines, and can withstand certain laying traction, but the cable can not bear external force, and single-core cable is not allowed to be laid in magnetic material pipeline. It is necessary to bear the external force of the machine and add the steel tape armor.

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

Features: Maintain a normal operation for 90 minutes (minutes) in a burning environment.
