CONSTRUCTION


1. N2XH Cable Structure

  • Conductor: Typically composed of high-purity copper or aluminum, annealed for flexibility and low resistance.

  • Insulation: Cross-linked polyethylene (XLPE) insulation provides excellent thermal resistance (up to 90°C) and dielectric strength.

  • Shielding: A concentric copper tape or braid shield minimizes electromagnetic interference (EMI).

  • Jacket: Thermoplastic or thermosetting material (e.g., PVC or LSZH) offers abrasion resistance and flame retardancy.

2. N2XH-J Cable Structure

  • Conductor: Similar to NXXH but may include additional stranding for enhanced flexibility.

  • Insulation: XLPE with higher dielectric breakdown voltage, suitable for industrial high-voltage applications.

  • Armor: Steel-wire or tape armor protects against mechanical stress (e.g., rodent damage or crushing).

  • Outer Jacket: Reinforced with fiberglass or aramid yarn for tensile strength in harsh environments.

3. N2XH-O Cable Structure

  • Conductor: Copper with silver plating for improved conductivity in corrosive environments.

  • Insulation: Silicone rubber insulation for extreme temperature resilience (-60°C to +200°C).

  • Shielding: Dual-layer shielding (aluminum foil + copper braid) for superior EMI protection.

  • Jacket: Fluoropolymer (e.g., PTFE) resists UV, chemicals, and moisture, ideal for outdoor installations.

FAQ


1. What is N2XH cable?

N2XH is a European standard (EN) halogen-free flame-retardant power cable, where "N" denotes non-spreading flame and "XH" indicates cross-linked polyethylene (XLPE) insulation. The J/O suffixes differentiate between rigid (Class 1) and flexible (Class 5) conductor versions.


2. Key features of N2XH-J/O cables?

  • Fire safety: FRNC (Flame Retardant Non-Corrosive) sheath reduces smoke/toxic gas emission during fire incidents

  • Material: Copper conductor + XLPE insulation + LSOH (Low Smoke Zero Halogen) sheath

  • Certification: CE/TUV certified, compliant with EN 60332-3, IEC 60754-1 standards

3. Typical applications?

  • Public buildings (hospitals, hotels)

  • Industrial plants (chemical/oil facilities)

  • Transport systems (metro, railways)

4. Voltage rating & temperature range?

  • Rated voltage: 0.6/1kV

  • Operating temp: -40°C to +90°C (fixed installation)

  • Short-circuit withstand: +250°C (5 sec max)

5. Installation precautions?

  • Minimum bending radius: 12× cable diameter

  • Avoid parallel routing with high-voltage cables (keep ≥300mm spacing)

  • Use proper glanding tools for shield termination

6. How to identify conductor classes?

  • N2XH-J: Class 1 solid conductor (rigid)

  • N2XH-O: Class 5 stranded conductor (flexible)

7. Advantage over PVC cables?

  • 50% lower smoke density in fires (IEC 61034 test)

  • No corrosive halogen gases (IEC 60754-1 compliant)

8. Maintenance recommendations?

  • Annual insulation resistance test (>20MΩ·km)

  • Visual inspection for sheath damage in corrosive environments
