In today's life, the use of electrical appliances is very common, but this requires that our wire and cable have a lot of special features. Let's take a look at the characteristics and applications of several fire-retardant flame-retardant cables from Henan Kexin Cable:
1. ZR-VV: flame-retardant PVC insulated, PVC sheathed power cable can be laid in indoor, tunnels, cable trenches, pipelines, flammable and severely corrosive areas, but can not withstand mechanical external force. If you need to withstand mechanical external force plus steel strip armor.
Features: In the case of an open fire, remove the fire source and automatically extinguish ≤12s.
2. ZR-YJV: flame-retardant cross-linked polyethylene insulation, PVC sheathed power cable can be laid indoors, in tunnels and pipelines, can withstand a certain laying traction, but the cable can not withstand external forces, single-core cable It is not allowed to lay in magnetic material pipes. If you need to withstand mechanical external force plus steel strip armor.
Features: In the case of an open fire, remove the fire source and automatically extinguish ≤12s.
3, NH-VV: fire-retardant PVC insulation, PVC sheathed power cables can be laid in the indoor, tunnels, cable trenches, pipelines, flammable and severely corrosive places, but can not afford mechanical external force. If you need to withstand mechanical external force plus steel strip armor. Applicable to special requirements occasions, such as large-capacity power plants, nuclear power stations, underground railways, high-rise buildings.
4, NH-YJV: fire-resistant cross-linked polyethylene insulation, PVC sheathed power cables can be laid indoors, in tunnels and pipelines, can withstand a certain laying traction, but the cable can not withstand external forces, single core cable is not allowed Laying in magnetic material pipes. If you need to withstand mechanical external force plus steel strip armor. Applicable to special requirements occasions, such as large-capacity power plants, nuclear power stations, underground railways, high-rise buildings.
5. YJV: XLPE insulation, PVC sheathed power cables can be laid indoors, in tunnels, and in pipelines. They can withstand a certain amount of laying, but cables cannot withstand external forces. Single-core cables are not allowed to be laid. Magnetic material in the pipeline. If you need to withstand mechanical external force plus steel strip armor.
