The NYY power cable is a PVC-insulated and PVC-sheathed cable designed for 0.6/1 kV applications. It is widely used for fixed installations in industrial, commercial, and residential settings.
This cable complies with multiple international standards including IEC 60502, VDE 0276-603, BS 6346, and TSIEC 60502.
The NYY cable features a multi-layer structure engineered for optimal performance:
| Layer | Material | Function |
|---|---|---|
| Conductor | Solid or stranded copper | Excellent electrical conductivity + mechanical strength |
| Insulation | PVC | Electrical isolation, moisture & chemical resistance |
| Filling | PVC | Maintains structural stability, prevents internal shifting |
| Outer Sheath | PVC | Protection against mechanical stress, corrosion, environmental factors |
Conductor options:
Solid conductors – ideal for applications requiring rigidity
Stranded conductors – flexibility for installations with bending requirements
