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.

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
