The difference between WDZ cable and WDZN cable

WDZN cable

1. The main difference between WDZ and WDZN cables is that the WDZN fire-resistant cable conductors are wrapped with a layer of mica tape, so that the cables can be kept normally energized for a period of time under burning conditions.

2. The main feature of WDZ flame-retardant cable is that the cable is not easy to catch fire or the fire delay is only limited to a certain range. It is suitable for power stations, subways, tunnels, high-rise buildings, large industrial and mining enterprises, oil fields, and high-density cable laying. Coal mines and other places.

3. The main feature of WDZN fire-resistant cable is that in addition to the ability of the cable to transmit power under normal working conditions, the cable can still maintain normal operation for a certain period of time when it is on fire. It is suitable for nuclear power plants, subways, tunnels, high-rise buildings, etc. and fire safety Places related to firefighting and lifesaving.

4. The principle of fire-resistant cable and flame-retardant cable is different: the flame-retardant principle of halogen-containing cable is based on the flame-retardant effect of halogen, and the flame-retardant principle of halogen-free cable is to extinguish the fire by reducing the temperature of the precipitated water; the fire-resistant cable is based on the fire-resistant layer. The fire-resistant and heat-resistant characteristics of mica material ensure that the cable will work normally even in the event of a fire.

5. The price of WDZ cable is slightly lower than that of WDZN cable by 10-20%. This depends on the process and cost of each cable factory. Huacheng Cable provides you with cost-effective and safe wires and cables.
