WDZ-RYYP low smoke halogen-free cable

WDZ-RYYP low smoke halogen-free cable, WDZ-RY environmentally friendly cable
Purpose:
This product has superior flame retardant performance, with very little smoke during combustion and no corrosive gas escaping. It is widely used in nuclear power plants, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, radio and television stations, important military facilities, oil platforms, and places with concentrated personnel and low air density.
Product Description:
Product Features and Applications
This product is suitable for applications with high requirements for cable flame retardant properties, such as subways, high-rise buildings, shopping malls, theaters, power stations, chemical factories, urban squares, and other public utilities with AC rated voltage of 450/750V and below. The halogen-free and low smoke characteristics of cables result in slow spread, low smoke concentration, high visibility, low release of harmful gases, and easy evacuation of personnel in the event of a fire. The low corrosiveness of combustion gases also avoids damage to instruments and equipment. The low halogen and halogen-free characteristics greatly improve the aging resistance, UV resistance, and other radiation resistance of cable materials, thereby extending the service life of cables.
Use features
1. Cable rated voltage UO/U: 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: For unarmored cables, the bending radius should not be less than 6 times the outer diameter of the cable. For cables with armor or copper tape shielding structures, the bending radius should not be less than 12 times the outer diameter of the cable.
Main technical indicators
1. The cable should withstand a 3kV power frequency voltage test at ambient temperature without breakdown for 5 minutes
2. The transmittance of the cable should comply with the following table
Cable outer diameter D (mm) transmittance (%) ≥ Cable outer diameter D (mm) transmittance (%) ≥ D>407053. Non flammability (flame retardant properties) of cables: They should pass the Class B bundled combustion test in GB12666.5-90. The vertical combustion test of a single wire and cable should pass GB12666.2-90
4. The release amount of halogen acid gas complies with IEC754-1
5. The pH value and conductivity of the combustion gas comply with IEC754-2, with pH ≥ 4.3 and conductivity ≤ 10 μ S/mm.
