WDZ cable and WDZN cable are in fact often said low-smoke halogen-free cable, WDZ is low-smoke halogen-free flame retardant cable, and WDZN is low-smoke halogen-free flame retardant cable, the difference in the structure of the two is that WDZN is more than WDZ outside the conductor a layer of mica tape, is based on the refractory layer of mica material, heat resistance characteristics, It can withstand long-term combustion, and can maintain normal power supply for a period of time in the case of flame combustion.



WDZ is the meaning of low smoke halogen-free flame retardant, such as WDZ-YJY refers to low smoke halogen-free flame retardant copper wire and cable; WDZN is above the original low smoke halogen-free flame retardant performance, but also has fire resistance characteristics.

Many people do not know the definition of flame retardant wire and fire retardant cable, from its application characteristics, fire retardant cable can replace flame retardant cable, but flame retardant cable can not replace flame retardant cable. This is mainly because the basic principles of the two are different.

The design principle of flame retardant cable is completed by the flame retardant effect of halogen, but the principle of fire retardant cable is not the same as flame retardant cable. The structure of the flame-retardant cable has a mica material, which has a high fire resistance and can ensure normal application in a fire.

The use of the scene is also different: the flame retardant characteristics of WDZ can control the fire within a certain range when lit, so it is widely used in power plants, multi-storey buildings and other sites. The fire resistance of WDZN can maintain normal operation even when ignited, so it is often used in nuclear power plants and some fire safety related places.
