N2XH power cables with enhanced resistance to fire are used mostly in areas where harm to human life or material must be prevented in case of fire such as industrial and public buildings, hotels, subway systems, hospitals etc. These cables are suitable for dry and wet environments as well as for outer application but are not suitable for direct burial into earth or water.
N2XH cable is an XLPE insulated
LSZH sheathed power cable.
It is designed for fixed low voltage
power distribution systems.
The cable is suitable for industrial buildings,
public buildings, hotels, hospitals,
metro systems, tunnels and commercial facilities.
The XLPE insulation provides reliable
electrical performance and thermal stability.
The LSZH sheath helps reduce smoke emission
and corrosive gas release in the event of fire.
N2XH cable is commonly selected for areas
where human safety and equipment protection
are important.
It can be used in dry and damp locations.
It is suitable for indoor installation,
outdoor protected installation,
cable trays, ducts and protected cable routes.
It is not recommended for direct burial
without suitable mechanical protection.
The cable should be selected according to
voltage rating, number of cores,
conductor size, sheath colour,
installation method and project specification.

FAQ
What is N2XH cable used for?
N2XH cable is used for fixed
low voltage power distribution.
It is suitable for buildings,
public facilities, tunnels, hotels,
hospitals and metro systems.
What is the structure of N2XH cable?
N2XH cable normally has copper conductors,
XLPE insulation and LSZH sheath.
It is usually an unarmoured cable.
Is N2XH a halogen-free cable?
Yes. N2XH cable uses LSZH
or halogen-free sheath material.
It helps reduce smoke and corrosive gas
in the event of fire.
Is N2XH a fire resistant cable?
N2XH is generally a flame retardant
and halogen-free power cable.
It should not be described as a
circuit integrity fire resistant cable
unless the project standard confirms it.
Can N2XH cable be used underground?
It can be used in protected ducts
or protected cable routes.
For direct burial, armoured cable
or additional mechanical protection
may be required.
What is the difference between
N2XH and N2XY?
N2XH has an LSZH / halogen-free sheath.
N2XY normally has a PVC sheath.
N2XH is preferred where low smoke
and halogen-free performance is required.
What information is required for quotation?
Please confirm voltage rating,
number of cores, conductor size
and cable length.
Installation method, sheath colour,
standard and destination port
are also required.
Can BURYCABLE supply N2XH cable?
Yes. BURYCABLE can supply N2XH
XLPE insulated LSZH power cables.
We can support different conductor sizes,
core numbers, lengths and packing requirements.
