0.6/1kV N2XCH Cable

What is N2XCH Cable?

The N2XCH IEC 60502-1 cable is a low-voltage, halogen-free, flame-retardant, concentric copper-screened power and control cable rated at 0.6/1kV, manufactured with plain copper conductors, XLPE insulation, a halogen-free inner bedding layer, a concentric copper wire and tape screen (CWS), and a black LSZH outer sheath complying with IEC 60502-1 and DIN VDE 0276 Part 604 standards. It is engineered to transmit primary electrical energy and secondary control signals in installations where human life and sensitive electrical equipment require protection against corrosive acid fumes and dense smoke during fire incidents.

Designed for installation in public commercial complexes, power stations, industrial automation lines, and rail transport facilities, the cable is suitable for indoor and outdoor exposed trays, channels, conduits, and direct concrete casting, although direct burial in earth and immersion in water are not permitted. The integrated concentric conductor serves simultaneously as a low-impedance protective neutral/earth (PEN/PE) conductor and a 100% electrostatic shield that deflects electromagnetic interference (EMI), while the flame-retardant non-corrosive (FRNC) outer jacket ensures bunched flame retardancy in compliance with IEC/EN 60332-3-24.

N2XCH Cable Construction

• Conductor: Plain annealed copper conforming to EN 60228: Class 1 solid circular (RE) for cross-sections up to 16mm², Class 2 circular stranded (RM) for 25mm², and Class 2 sectorial compacted stranded (SM/SMv) from 35mm² up to 240mm².
• Insulation: Cross-Linked Polyethylene (XLPE) compound providing high dielectric strength, low dielectric loss, and continuous operating thermal resistance up to +90°C.
• Inner Sheath: Extruded halogen-free compound serving as a protective bedding cushion over the assembled cores.
• Concentric Conductor / Screen: Helically applied plain copper wires bound with an open counter-helix of copper tape (CWS) providing fault-current return and electromagnetic shielding.
• Armour: Unarmoured, lightweight profile featuring metallic concentric screening for electrostatic suppression without magnetic steel tape or wire.
• Outer Sheath: Thermoplastic Low Smoke Zero Halogen (LSZH / FRNC) compound offering flame retardancy, low smoke opacity, and acid-free emission.
• Core Identification: 2-core: Brown, Blue; 3-core: Brown, Black, Grey; 4-core: Blue, Brown, Black, Grey; 5-core: Black, Blue, Brown, Black, Grey; 7 cores and above: Black with printed numbering.
• Sheath Colour: Black.

Applications

N2XCH 0.6/1kV cables are designed for fixed installations in power supply distribution and industrial telemetry networks where stringent safety protocols demand non-toxic, self-extinguishing electrical cabling. They are engineered for indoor and outdoor installations, perimeter raceways, perforated cable ladders, and cast concrete, but are not rated for direct underground burial without protective ducting or long-term submersion in water.

• Commercial & Public Infrastructure: Sub-main distribution circuits in airports, hospitals, high-rise buildings, railway stations, and shopping centers.
• Industrial & Power Generation Plants: Feeding medium-to-low voltage switchgear, transformer secondaries, motor control centers (MCC), and plant machinery.
• Electromagnetically Sensitive Facilities: Data processing hubs, telecommunication buildings, and automation control rooms requiring concentric copper screening to prevent electromagnetic crosstalk.
• Cast Concrete & Building Risers: Embedded wiring in structural concrete conduits, riser shafts, and cable trunking systems.

Specifications & Dimensions

The N2XCH IEC 60502-1 cable series encompasses multi-core configurations ranging from 2-core to 5-core power formats (1.5mm² to 240mm²) as well as multi-core control formats from 7 cores up to 30 cores (1.5mm² and 2.5mm²). Operating at a rated voltage of 0.6/1kV across a fixed temperature spectrum of -30°C to +90°C, it requires a minimum bending radius of 15 times the overall diameter. Maximum conductor DC resistance values at 20°C range from 12.1 Ω/km (1.5mm²) down to 0.0754 Ω/km (240mm²), with current-carrying capacities in air spanning 25A on 1.5mm² up to 565A on 240mm² multi-core configurations and nominal overall outer diameters ranging from 12mm up to 68mm, adhering strictly to IEC 60502-1 and DIN VDE 0276 Part 604 tolerances.

Frequently Asked Questions

Q: What is the primary role of the concentric copper conductor (CWS) in N2XCH cable?
A: The concentric conductor layer serves a dual engineering purpose: it acts as a low-impedance protective earth (PE) or neutral (PEN) conductor while providing a continuous 360-degree electrostatic shield that suppresses electromagnetic interference (EMI) and prevents stray voltage leakage.

Q: Can N2XCH cable be installed directly in the ground or submerged in water?
A: No, per the official specification, N2XCH is suitable for indoor, outdoor, tray, and cast concrete installations, but is explicitly not designed for direct burial in the ground or long-term submersion in water; for direct ground burial, steel tape or steel wire armoured variants must be selected.

Q: What is the difference between conductor designations RE, RM, and SM?
A: RE denotes a Class 1 solid circular copper conductor, RM indicates a Class 2 stranded round circular copper conductor, and SM/SMv represents a Class 2 sector-shaped stranded compacted conductor designed to reduce overall cable diameter and weight on larger cross-sections.

Q: What commercial delivery lead times does Huadong Cable Group provide for international export orders?
A: Standard manufacturing lead times for export orders typically range from 15 to 25 working days depending on core configuration, conductor cross-section, and total production drum volume.
