How does WDZ cable differ from WDZN cable?

WDZ cable and WDZN cable difference is how? 1, WDZ and WDZN cable is the main difference between the main WDZN fire-resistant cable conductor wrapped around a layer of mica tape, so that the cable has a combustion situation to maintain the normal energized for a period of time. 2, WDZ flame-retardant cables are not easy to catch fire or fire delayed ignition is only confined to a certain extent, applicable to the cable laying of a higher degree of density of the Power stations, subways, tunnels, high-rise buildings, large industrial and mining enterprises, oil fields, coal mines and other places. 3, WDZN fire-resistant cables are mainly characterized by the cable in addition to the normal working conditions of transmission of electricity, the cable in the fire combustion can still be maintained for a certain period of time of normal operation, suitable for nuclear power plants, subways, tunnels, high-rise buildings and other fire safety and fire life-saving related to the place. 4, fire-resistant cables are different with the Fire-retardant cable principle is different: halogen cable flame retardant principle is to rely on the halogen flame retardant effect, halogen-free cable flame retardant principle is to rely on the precipitation of water to reduce the temperature to extinguish the fire; fire-resistant cable is to rely on the fire-resistant layer in the fire-resistant mica material, heat-resistant properties, to ensure that the cable in the fire is also working properly. 5, WDZ cable price is slightly lower than the WDZN cable by 10 ~ 20%. This depends on each cable factory process and cost price varies, Sui Xing cable to provide you with cost-effective, safe wire and cable.
