WDZA-YJY23 is a Low Smoke Zero Halogen (LSZH), Flame Retardant Grade A, XLPE insulated, steel tape armored power cable, designed for fixed power transmission and distribution systems. It minimizes smoke emission and eliminates corrosive halogen gases during fire conditions.
Cable Construction
Typical cable structure: Copper Conductor → XLPE Insulation → Filling → Wrapping Tape → Inner Sheath → Double Steel Tape Armor → LSZH Outer Sheath
Main components include:
- Copper Conductor: Excellent electrical conductivity and stable current-carrying performance
- XLPE Insulation: Superior electrical performance, high temperature resistance, and long service life
- Double Steel Tape Armor: Enhanced mechanical protection and compression resistance
- LSZH Outer Sheath: Low smoke and no toxic halogen gases during combustion
Specification Description
3×95+2×50mm² means 3 × 95mm² main conductors for three-phase power supply (L1/L2/L3) and 2 × 50mm² auxiliary conductors usually used as Neutral (N) and Protective Earth (PE). Suitable for three-phase five-wire systems.
