6 kinds of commonly used power cable characteristics

Power cable models are more different models also have different characteristics and suitable occasions, so we still have to understand the characteristics of different power cables, so as to find their own power cable models, here to give you a brief introduction to 6 Common power cable features:

1, PVC insulated, PVC sheathed power cable

Can be laid indoors, tunnels, cable ditches, pipelines, flammable and severely corroded areas, but can not afford mechanical external force. To withstand mechanical external force plus steel tape armor.

2, XLPE insulated, PVC sheathed power cable

Can be laid indoors, tunnels and pipes can withstand a certain laying by, but the cable cannot afford the role of external force, single-core cable is not allowed to lay in the magnetic material pipe. To withstand mechanical external force plus steel tape armor.

3, flame-retardant PVC insulation, PVC sheathed power cable

Can be laid indoors, tunnels, cable ditches, pipelines, flammable and severely corroded areas, but can not afford mechanical external force. To withstand mechanical external force plus steel tape armor. Features: In the case of open flame burning, remove the fire source, ≤ 12s automatically extinguished.

4, flame retardant XLPE insulated, PVC sheathed power cable

Can be laid indoors, tunnels and pipelines can withstand a certain laying traction, but the cable cannot afford external forces, single-core cable is not allowed to lay in the magnetic material pipe. To withstand mechanical external force plus steel tape armor.

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

5, fire-resistant PVC insulation, PVC sheathed power cable

Can be laid indoors, tunnels, cable ditches, pipelines, flammable and severely corroded areas, but can not afford mechanical external force. To withstand mechanical external force plus steel tape armor. Suitable for special occasions, such as high-capacity power plants, nuclear power plants, subway, high-rise buildings.

Features: In a burning environment, the protection of 90min (minutes) normal operation.

6, fire-resistant XLPE insulation, PVC sheathed power cables

Can be laid indoors, tunnels and pipelines can withstand a certain laying traction, but the cable cannot afford external forces, single-core cable is not allowed to lay in the magnetic material pipe. To withstand mechanical external force plus steel tape armor.

Suitable for special occasions, such as high-capacity power plants, nuclear power plants, subway, high-rise buildings.

Features: In a burning environment, maintain 90min (minutes) normal operation.
