WDZA-YJY23 is a Low Smoke Zero Halogen (LSZH), Flame Retardant Grade A, XLPE insulated, double steel tape armored power cable designed for low-voltage power transmission and distribution systems. It combines flame retardancy, low smoke zero halogen performance, and mechanical protection.
Cable Construction
- Typical cable structure:
Copper Conductor → XLPE Insulation → Filling → Wrapping Tape → Inner Sheath → Double Steel Tape Armor → LSZH Outer Sheath
- Copper Conductor: Excellent electrical conductivity, typically using Class 2 stranded copper conductor.
- XLPE Insulation: Superior electrical properties, high temperature resistance, and long service life.
- Double Steel Tape Armor: Enhanced compression resistance, impact resistance, and mechanical protection.
- LSZH Outer Sheath: Low smoke and no corrosive halogen gases during combustion.
Specification Description
3×120+1×70mm² means 3 × 120mm² main conductors for three-phase power supply (L1/L2/L3).
1 × 70mm² auxiliary conductor is typically used as Neutral (N) or Protective Earth (PE).
This is a typical 3+1 core low-voltage power cable configuration.
