APPLICATION

600/1000V 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.

Fire performance can be supplied according to

BS 6387, IEC 60331 and BS 8491 requirements,

subject to the project specification.

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 multicore unarmoured cable,

it does not provide metallic armour protection.

It is suitable for cable trays,

cable ducts, risers 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, number of cores,

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?

This cable is designed according to

BS 8573 requirements.

Fire performance should be confirmed

according 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 multicore

unarmoured fire resistant cable.

If armoured construction is required,

please confirm it separately.

Is this cable single core?

No. This page is for multicore cable.

Single core 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,

number of cores, conductor size,

cable length and fire performance requirement.

Installation method, sheath colour,

standard and destination port

are also required.

Can BURYCABLE supply BS 8573

Mica XLPE LSZH fire resistant cable?

Yes. BURYCABLE can supply BS 8573
