NAYY Cable is a multi-core power cable according to IEC 60502. It is designed for fixed installations in industrial distribution systems, underground ducts and mains power lines in buildings. Unlike NYY cables, which are usually made of aluminum conductors with a double layer of PVC, NAYY electrical cables combine economy and high load carrying capacity, especially for long distance transmission projects. Whereas NYY is mostly made of copper conductors with a single layer of PVC and is used in light commercial buildings. The ““NAYY cable meaning” refers to:
N: Harmonized European Standard.
A: Aluminum conductor.
YY: Double PVC insulation (inner insulation + outer jacket).

Product Features

• Double-layer PVC protection: Inner insulation (70°C) and outer jacket (UV, acid and alkali resistant) provide double protection for wet basements or outdoor direct burial.
• Compression Resistant Design: Sheath compression strength ≥15 MPa; resistant to underground geotechnical pressure.
• Multi-core configurations: 2 to 5 core configurations (e.g. NAYY 4x150mm²) are supported, each core is individually insulated to avoid the risk of short circuits.
• CE and RoHS certified; complies with IEC 60332-1 flame retardant standard.

Cable Construction

• Conductor:  Aluminium conductor, round solid (RE), sector-shaped solid (SE), round stranded (RM) resp, sector-shaped stranded (SM)
• Insulation: PVC (Polyvinyl chloride)
• Outer Sheath: PVC (Polyvinyl chloride)
• Outer Sheath Color: Black
