The full name of the WDZYJFE cable specification is: Irradiated Cross-linked Polyethylene Insulated, Low-Smoke, Halogen-Free, Flame-Retardant Polyolefin Sheathed Power Cable.
I. Components of the WDZ-YJFE Cable:
WDZ - Halogen-Free, Low-Smoke, Flame-Retardant
YJF - Irradiated Cross-linked Polyethylene Insulation
E - Polyolefin Sheath
Specific Cable Specification and Model Naming Rules: Cable Specifications and Models
Low-Smoke, Halogen-Free (Cross-linked) Polyolefin Insulated and Sheathed Power Cable
II. Scope of Application of the WDZ-YJFE Cable:
1. The long-term allowable operating temperature of the cable conductor is 70°C and 90°C.
2. The cable installation temperature should not be lower than 0°C.
3. This product is not only flame-retardant, but also low-smoke and pollution-free. Also known as clean cable or green cable, it is suitable for power transmission and distribution systems with rated voltages of 0.6/1kV and below, AC 50Hz, and for automation equipment lines with high flame-retardancy requirements. It is particularly suitable for use in high-rise buildings, hotels, restaurants, shopping malls, and other enclosed environments with concentrated personnel and difficult evacuation. Users may also refer to GB50217-94 "Design Code for Power Engineering Cables" for selection.
4. Special Specifications, Indicators, and Standards for Halogen-Free Flame-Retardant Cables
1) Combustion Gas Corrosive Conductivity (pH <=10μs/mm) >=4.3 (IEC 754-2)
2) Cable Combustion Smoke Density (Light Transmittance >=60%) (GB/T17651.2)
