Types of fire-resistant flame retardant cables and application occasions
1. Fire-resistant cross-linked polyethylene insulated PVC sheathed power cable can be laid indoors, in tunnels and pipelines.
Can withstand certain laying traction, but the cable can not withstand external forces, single-core cables are not allowed to magnetic laying material pipeline.
If the need to withstand mechanical external forces and wrapped steel belt armor.
Suitable for special requirements, such as high-capacity power plants, nuclear power plants, underground railroads, high-rise buildings, etc.
2. Cross-linked polyethylene insulated PVC sheathed power cables can be laid indoors, in tunnels, and pipes.
It can withstand certain laying and traction, but the cable cannot withstand external forces, and single-core cables are not allowed to be laid in magnetic material pipes.
If you need to withstand mechanical external forces and wrapped steel belt armor.
3. Flame-retardant PVC insulated, PVC sheathed power cables can be laid indoors, in tunnels, cable trenches, pipelines, and flammable and corrosive places, but they cannot withstand external mechanical forces.
If it needs to withstand a mechanical external force, the package steel belt armor. Features: In the case of open flame burning, remove the source of fire, ≤ 12S automatically extinguishes the fire.
4. Flame retardant cross-linked polyethylene insulated, PVC fuel sheathed power cable can be laid indoors, in tunnels and pipelines.
Can withstand certain laying traction, but the cable can not withstand external forces, not allowed to lay a single-core cable in the magnetic material pipeline.
If need to withstand a mechanical external force, package steel belt armored. Features: In the case of open flame burning, remove the source of fire, and automatically extinguish the fire.
5. Fire-resistant PVC insulated, PVC sheathed power cable can be laid indoors, in tunnels, cable trenches, pipelines, and flammable and corrosive places, but cannot withstand external mechanical forces.
If need to withstand a mechanical external force, package steel belt armor. Suitable for special requirements, such as high-capacity power stations, nuclear power stations, underground railroads, high-rise buildings, etc.
