APPLICATION

600/1000V single core Mica + XLPE

insulated LSZH sheathed fire resistant cable

is designed for critical power circuits.


It is suitable for power stations,

metro systems, tunnels, airports,

petrochemical plants, hospitals,

hotels and high-rise buildings.


The mica tape layer helps maintain

circuit integrity during fire conditions.


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.


This cable is commonly selected for projects

where fire safety, flame retardance

and low smoke performance are required.


As a single core unarmoured cable,

it does not provide metallic armour protection.


It is suitable for cable trays,

cable ducts, risers, panels

and protected fixed installation routes.


Where additional mechanical protection

is required, the cable should be installed

with suitable protection.


The cable should be selected according to

voltage rating, conductor size,

fire performance, installation method

and project specification.

FAQ


What is this cable used for?


It is used for critical power circuits

where fire safety is important.


It is suitable for power stations,

metro systems, tunnels, airports,

hospitals, hotels and high-rise buildings.



What standard does this cable follow?


The cable design is based on BS 8573.


Fire performance can be supplied according to

BS 6387, IEC 60331 and BS 8491 requirements,

subject to the project specification.




What is the function of mica tape?


Mica tape helps maintain circuit integrity

during fire conditions.


It supports continued operation of

critical circuits for a specified time.



Is this cable LSZH?


Yes. This cable has an LSZH sheath.


The sheath helps reduce smoke emission

and corrosive gas release in the event of fire.



Is this cable armoured?


No. This page is for single core

unarmoured fire resistant cable.


If armoured construction is required,

please confirm it separately.



Is this cable multicore?


No. This page is for single core cable.


Multicore fire resistant cable

is available as a separate type.



Can this cable be used underground?


It can be used in protected ducts

or protected underground routes.


For direct burial or demanding routes,

armoured cable may be required.



What information is required for quotation?


Please confirm voltage rating,

conductor size, cable length

and fire performance requirement.


Installation method, sheath colour,

standard and destination port

are also required.
