NH-VV: Fire-resistant PVC insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, cable trenches, pipelines, and in flammable and severely corrosive environments, but cannot withstand mechanical forces. Steel tape armor can be added if mechanical forces are required. Suitable for special applications such as large-capacity power plants, nuclear power plants, subways, and high-rise buildings.
Features: Maintains 90 minutes of normal operation in a burning environment.
NH-YJV: Fire-resistant cross-linked polyethylene insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, and pipelines, and can withstand certain pulling forces during installation. However, the power cable cannot withstand external forces, and single-core cables cannot be installed in magnetic pipes. Steel tape armor can be added if mechanical forces are required. Suitable for special applications such as large-capacity power plants, nuclear power plants, subways, and high-rise buildings.
Features: Maintains 90 minutes of normal operation in a burning environment. VV: PVC insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, cable trenches, ducts, and in flammable and severely corrosive environments, but cannot withstand mechanical forces. Steel tape armor should be applied if mechanical forces are required.
YJV: Cross-linked polyethylene insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, and ducts, and can withstand certain cable draws. However, the cable cannot withstand external forces, and single-core cables are not permitted in magnetic pipes. Steel tape armor should be applied if mechanical forces are required.
ZR-VV: Flame-retardant PVC insulated, PVC sheathed power cable
Can be installed indoors, in tunnels, cable trenches, ducts, and in flammable and severely corrosive environments, but cannot withstand mechanical forces. Unlike low-smoke halogen-free cables, steel tape armor should be applied if mechanical forces are required.
Features: In the event of an open flame, the fire will automatically extinguish in 12 seconds or less upon removal of the source. ZR-YJV: Flame-retardant cross-linked polyethylene insulated, PVC sheathed power cable.
Can be installed indoors, in tunnels, and in pipelines. Can withstand certain traction during installation. However, the cable cannot withstand external forces, and single-core cables are not permitted in magnetic pipes. If mechanical resistance is required, steel tape armor is added.
