0.6/1kV N2XBY Cable

What is N2XBY Cable?

N2XBY Cable is a 0.6/1kV Class 2 stranded copper XLPE insulated double steel tape armoured (STA) power cable manufactured in compliance with IEC 60502-1, VDE 0276-603, IS 1516.1, and IEC/EN 60228 standards. It is specifically engineered to provide uninterrupted electrical power distribution across demanding industrial and utility infrastructure where physical protection against mechanical impacts and compression is critical.

The cable combines stranded plain copper conductors, thermally resilient XLPE insulation, a protective PVC inner filler bed, two helically applied galvanized steel tapes, and a flame-retardant black PVC outer jacket. The double steel tape armour provides a continuous 360-degree protective barrier against heavy underground earth pressure, accidental mechanical crushing, and rodent damage without compromising installation flexibility in cable channels and ducting networks.

N2XBY Cable Construction

• Conductor
• Class 2 stranded plain copper conductor per IEC/EN 60228, offering superior conductivity and physical durability.
• Insulation
• XLPE (Cross-Linked Polyethylene) rated for high thermal performance with operating limits up to +90°C.
• Inner Filler
• Polyvinyl Chloride (PVC) compound filling the internal interstices to form a smooth circular bed
• Armour Layer
• Double galvanized steel tape (STA) counter-wrapped to deliver full mechanical crushing resistance.
• Outer Sheath
• Flame-retardant black PVC (Polyvinyl Chloride) compliant with IEC/EN 60332-1.
• Core Identification
• 2 core: Brown, Blue; 3 core: Brown, Blue, Green/Yellow; 4 core: Brown, Black, Grey, Green/Yellow; 5 core: Brown, Blue, Black, Grey, Green/Yellow; 7 cores and above: Black with printed numbers or Green/Yellow.

Applications

N2XBY 0.6/1kV Armoured Power Cable is engineered for fixed indoor and outdoor installations requiring severe mechanical protection. Key application sectors include:

Power Generating Stations & Switchgear: Connecting main distribution panels, transformers, and switchgear units inside high-voltage substations and industrial power facilities.
Subterranean Channels & Cable Ducts: Routed through direct underground ducts, subterranean concrete trenches, and industrial cable channels.
Harsh Industrial Environments: Deployed across petrochemical processing units, heavy manufacturing plants, and mining sites subject to physical compulsion and impact stress.

Frequently Asked Questions

Q: What is the main structural advantage of Double Steel Tape Armour (STA) in N2XBY cables?
A: Double steel tape armour provides continuous circumferential protection against static earth crushing pressure, stone impact, and rodents during direct underground burial.

Q: What is the maximum operating temperature limit for N2XBY cable?
A: With high-grade XLPE insulation, N2XBY operates continuously at conductor temperatures up to +90°C and supports emergency short-circuit conditions up to +250°C.

Q: Can N2XBY cable be installed in wet or damp underground ducts?
A: Yes, the combination of XLPE insulation and a heavy PVC outer sheath provides excellent protection against moisture ingress, making it suitable for damp cable channels and conduits.

Q: What payment terms does Huadong Cable Group accept for international B2B orders?
A: We accept Telegraphic Transfer (T/T) and Irrevocable Letter of Credit (L/C) at sight for international transactions.
