If you are searching for “N2XBH cable”, chances are you want to understand what this cable model means, where it is used, how it compares with other LSZH armoured cables, and whether it is suitable for high-risk fire environments such as tunnels, buildings, or industrial plants.
What Does the N2XBH Cable Designation Mean?
The cable name N2XBH follows European (VDE-based) identification logic:
N – Standard cable according to VDE / IEC
2X – XLPE insulated copper conductor
B – Steel tape armoured
H – Halogen-free, flame-retardant (LSZH) outer sheath
In simple terms, N2XBH is a low-voltage, fire-safe, mechanically protected power cable, designed for locations where human safety, fire resistance, and smoke reduction are critical.
Why Is N2XBH Considered a Fire-Safe Power Cable?
N2XBH is engineered specifically for high fire-risk and high-occupancy environments, combining LSZH materials with IEC-certified flame-retardant performance.
Key Fire-Safety Features:
LSZH (Low Smoke Zero Halogen) materials
No corrosive or toxic gases during combustion
Low smoke density for improved visibility during evacuation
Flame retardant according to IEC 60332-3-24 (Category C)
This makes N2XBH suitable for public buildings, tunnels, refineries, hospitals, and data centers.
Which International Standards Does N2XBH Comply With?
N2XBH cables are manufactured according to multiple global standards:
IEC 60502-1
DIN VDE 0276-604
HD 604 S1
IS 1516-1
IEC / EN 60754-1 & 2 (Halogen-free)
IEC / EN 61034-1 & 2 (Low smoke)
These certifications make the cable widely accepted in international and ASEAN projects, including Indonesia.
Where Is N2XBH Cable Commonly Used?
Typical Application Scenarios
Oil & gas refineries
Hotels, shopping malls, and offices
Hospitals and schools
Road and railway tunnels
Power plants
Data processing centers
High-rise buildings
Densely populated business districts
In Indonesia, these environments often demand LSZH armoured solutions due to fire regulations and evacuation safety concerns.
How Does N2XBH Compare with Other Similar Cables?
N2XBH vs N2XBY vs N2XRY
Feature | N2XBH | N2XBY | N2XRY |
|---|---|---|---|
Insulation | XLPE | XLPE | XLPE |
Armour | Double steel tape | Steel tape | Steel wire |
Sheath | LSZH | PVC | PVC |
Fire safety | Excellent | Medium | Medium |
Smoke & toxicity | Very low | High | High |
Public buildings | ✅ Recommended | ❌ Not ideal | ❌ Not ideal |
Conclusion:
For fire-critical environments, N2XBH is clearly superior.
What Are the Installation Recommendations for N2XBH Cable?
Best Practices
Maintain minimum bending radius (12×OD)
Use LSZH-compatible glands and accessories
Proper earthing of steel tape armour
Avoid direct flame exposure during installation
Suitable for indoor, outdoor, and underground installation
Common Installation Methods
Cable trays
Cable ladders
Conduits
Direct burial (with protection)
Is N2XBH Used in Real Projects in Indonesia?
Indonesian Tunnel Infrastructure Project – Jakarta
Project type: Urban road tunnel
Cable used: N2XBH 0.6/1kV
Reason for selection:
LSZH compliance with local fire authority
Low smoke for evacuation safety
Strong mechanical protection during installation
Long-term reliability in humid conditions
Frequently Asked Questions (FAQ)
Is N2XBH suitable for underground installation?
Yes. Its double steel tape armour and LSZH sheath make it suitable for underground use with proper bedding.
Can N2XBH replace PVC armoured cables?
Yes, especially where fire safety and human protection are required.
Is N2XBH oil-resistant?
It offers moderate resistance; for heavy oil exposure, additional protection is recommended.
Does LSZH mean fire-resistant?
LSZH means low smoke and no halogen. N2XBH is flame retardant, not circuit-integrity fire-resistant.
Why Choose N2XBH for Modern Power Distribution?
Enhanced fire safety
Reduced toxic smoke
Strong mechanical protection
International standard compliance
Ideal for urban and industrial Indonesia
If you are planning a power distribution project in Indonesia or Southeast Asia and need a safe, compliant, and reliable LSZH armoured cable, N2XBH 0.6/1kV is a proven solution.
