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

It can be laid indoors, in tunnels and pipelines, and can be used as a definite laying traction, but the cable cannot be subjected to external forces, and single-core cables are not allowed to be laid in magnetic pipelines. If you need to withstand the external force of the machine, add steel tape armor. It is practically used in places with special requirements, such as large-capacity power plants, nuclear power plants, underground railways, and high-rise buildings.

2. YJV: XLPE insulated, PVC sheathed power cable

It can be laid indoors, in tunnels and in pipelines, and can be used as a definite guide for laying, but the cables cannot be subjected to external forces, and single-core cables are not allowed to be laid in magnetic pipelines. If you need to withstand the external force of the machine, add steel tape armor.

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

It can be laid indoors, tunnels, cable trenches, pipelines, flammable and severely corroded places, but it cannot be subjected to external forces from the machine. If you need to withstand the external force of the machine, add steel tape armor. Features: In the environment of open flame, remove the fire source, and extinguish automatically within 12s.

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

It can be laid indoors, in tunnels and pipelines, and can be used as a definite laying traction, but the cable cannot be subjected to external forces, and single-core cables are not allowed to be laid in magnetic pipelines. If you need to withstand the external force of the machine, add steel tape armor. Features: Under the environment of open flame, remove the fire source, and extinguish automatically within 12s.

5. NH-VV: fire-resistant PVC insulated, PVC sheathed power cable

It can be laid indoors, tunnels, cable trenches, pipelines, flammable and severely corroded places, but it cannot be subjected to external forces from the machine. If you need to withstand the external force of the machine, add steel tape armor. It is suitable for places with special requirements, such as large-capacity power plants, nuclear power plants, subways, high-rise buildings, etc.

In recent years, in the global power system fire alarms, the proportion of power supply stops due to power cables is on the rise. Therefore, in power plants, substations, etc., where there are a large number of electrical equipment and a large number of cables are laid by the moose, flame-retardant cables are used to prevent fire from spreading, and the uninterrupted power supply of the tight loop with flame-resistant cables is becoming increasingly tense. However, some electrical plan staff are not clear about the concept of flame-retardant cables and fire-resistant cables, and do not know the characteristics of the two. As a result, they cannot accurately plan the selection of these two cables according to the power supply requirements. When planning agency or supervision work is held on site The laying methods of these two cables cannot be accurately guided. Therefore, a comprehensive and accurate understanding of flame-retardant and fire-resistant cables is the main condition for accurately selecting them.
