Product Features and Applications
This product is suitable for subways, high-rise buildings, shopping malls, theaters, power stations, chemical factories, city squares, and other public utilities that require high flame-retardant properties for cables, with rated voltages of 450/750V and below.

WDZ-RYY Low Smoke Halogen-Free Flame Retardant Cable, WDZN-RYY Low Smoke Halogen-Free Flame Retardant and Fireproof Flexible Cable

Halogen-free and low-smoke cables have slow flame spread, low smoke concentration, high visibility, and minimal release of harmful gases during a fire, making it easier for people to evacuate.

Low corrosiveness of the combustion gases also prevents damage to instruments and equipment. The low halogen and halogen-free properties significantly enhance the cable material's resistance to aging and ultraviolet radiation, as well as other radiations, thereby extending the service life of the cables.
