NYY is a PVC-insulated and sheathed copper power cable designed for fixed installations in dry, damp, or moderately corrosive environments. Compliant with DIN VDE 0276 and IEC 60502, it is widely used for power distribution in buildings, industrial plants, and underground conduits. Its robust construction ensures durability and safety in low-voltage applications.
Voltage Rating: 0.6/1 kV (AC).
Temperature Range:
Operating: -5°C to +70°C (ambient).
Short-Circuit Tolerance: +160°C (max 5 seconds).
Construction:
Conductor: Copper (Class 1 solid or Class 2 stranded per IEC 60228).
Insulation: PVC (polyvinyl chloride) for electrical insulation and moisture resistance.
Sheath: PVC for mechanical protection and flexibility.
Certifications: CE, RoHS, and IEC 60332-1 (flame retardancy
Fixed electrical installations in residential, commercial, and industrial buildings.
Underground or ducted power distribution systems.
Lighting circuits, machinery wiring, and control panels.
Standard parameters for NYY cables are listed below. Custom configurations (e.g., multi-core, armored) are available.
