0.6/1kV N2XBH Cable

What is N2XBH Cable?

N2XBH Cable is a 0.6/1kV double steel tape armoured (STA) power cable featuring Cross-Linked Polyethylene (XLPE) insulation and Halogen Free Flame Retardant (HFFR/LSZH) construction, certified under DIN VDE 0276-604, TS HD 604.S1, IS 1516.1, and IEC 60502-1 standards. Designed for high-density public buildings and heavy-duty industrial infrastructure, it balances mechanical durability with maximum life safety protection during fire hazards.

The cable combines Class 2 stranded plain copper conductors, thermally resilient XLPE insulation, an HFFR inner filler bed, double galvanized steel tape armour, and a halogen-free outer sheath available in black or green. Under fire conditions, N2XBH does not propagate flames, emits virtually zero corrosive acid gases, and produces minimal smoke, preventing toxic smoke accumulation in enclosed spaces while safeguarding sensitive electronic hardware.

N2XBH Cable Construction

Conductor

Class 2 stranded plain copper conductor per IEC 60228, providing efficient electrical power transmission and flexibility.

Insulation

XLPE (Cross-Linked Polyethylene) rated for continuous high-temperature operating loads up to +90°C.

Filler Layer

HFFR (Halogen Free Flame Retardant) compound filling the inner core interstices.

Armour Layer

Double galvanized steel tape (STA) wrapped around the core assembly to shield against mechanical crushing, physical impact, and rodents.

Outer Sheath

HFFR (Halogen Free Flame Retardant) polyolefin compound offering robust chemical and flame resistance.

Core Identification

2 core: Blue, Brown; 3 core: Brown, Black, Grey; 4 core: Blue, Brown, Black, Grey; 5 core: Blue, Brown, Black, Grey, Black.

Outer Sheath Colours

Black or Green.

Applications

N2XBH 0.6/1kV Armoured Cable is engineered for power distribution in high-density public venues, commercial complexes, and industrial sites where fire safety, low smoke emission, and mechanical protection are mandatory. Key installation environments include:

Public & High-Occupancy Facilities: Extensively deployed in hospitals, schools, hotels, high-rise buildings, data processing centers, and populated business centers where toxic smoke during a fire presents an extreme threat to life safety.
Transport Infrastructure & Subterranean Runways: Ideal for power and auxiliary distribution inside railway tunnels, underground stations, air transport terminals, and indoor utility conduits.
Industrial & Hazardous Locations: Installed in oil refineries, power generating plants, and chemical processing facilities requiring mechanical steel tape protection against compression and external strain.

Frequently Asked Questions

Q: What is the benefit of Double Steel Tape Armour (STA) in N2XBH cables?
A: Double steel tape wrapping provides complete circumferential protection against physical crushing, underground pressure, and rodent attacks without adding excessive weight compared to wire armour.

Q: What makes N2XBH cable suitable for high-occupancy public buildings?
A: Its HFFR (LSZH) bedding and sheath materials ensure that during a fire event, the cable emits no toxic halogen acid gases and produces low smoke density, allowing safe evacuation and preserving visibility.

Q: What is the maximum continuous working temperature of N2XBH cable?
A: Equipped with XLPE insulation, N2XBH supports a maximum continuous conductor operating temperature of +90°C and a short-circuit thermal limit of +250°C.

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 B2B transactions.
