Hello:
WDZ-YDE means low-smoke, halogen-free, flame-retardant power cable.
This product is suitable for subways, high-rise buildings, shopping malls, theaters, power stations, chemical plants, city squares and other public utilities where the AC rated voltage is 450/750V and below, etc., which require high cable flame retardant properties. occasion. The cable's halogen-free and low-smoke, low-halogen and low-smoke characteristics mean that when a fire occurs, it spreads slowly, has low smoke concentration, high visibility, and small harmful gas release, making it easier for personnel to evacuate. The combustion gas is less corrosive and avoids damage to instruments and equipment. The low-halogen and halogen-free characteristics greatly improve the resistance of cable materials to aging, ultraviolet rays and other radiation, thereby extending the service life of the cable. , and can also be produced according to the technical requirements required by users. Product implementation standard GB9330-88 Q/WTL11-2003 Usage characteristics 1. Rated voltage UO/U of the cable: 450/750V, AC polyolefin UO/U is 0.6/1KV 2. The long-term working temperature of the cable is: -20℃-90℃ , -40℃-105℃ 3. Recommended bending radius: without armor should be no less than 6 times the outer diameter of the cable, and with armor or copper tape shielding structure should be no less than 12 times the outer diameter of the cable. Main technical indicators: The cable should withstand a power frequency voltage test of 3kV at ambient temperature without breakdown for 5 minutes.
I hope my answer can be helpful to you, thank you for accepting it.
