Application and Description

6491B LSZH single core cable to BS7211

and BS EN 50525-3-41 is designed for

fixed wiring and building wiring

applications.

It is suitable for residential,

commercial, industrial and public

building installations.

Typical applications include conduit

wiring, trunking systems, switchgear,

distribution boards, control panels

and electrical cabinets.

The cable is commonly used where

low smoke zero halogen performance

is required to reduce smoke emission

and corrosive gas release in the event

of fire.

The LSOH thermosetting insulation provides

reliable electrical performance,

thermal stability and safer fire behaviour

for indoor wiring systems.

6491B cable is normally used as a

single core insulated wire.

It should be installed in conduit,

trunking, panels or other protected

wiring systems where mechanical protection

is required.

Solid conductor, stranded conductor

and flexible conductor options may be

available according to project requirement.

The cable should be selected according to

voltage rating, conductor class,

conductor size, insulation colour,

installation method and project specification.

FAQ

What is 6491B cable used for?

6491B cable is used for fixed wiring,

conduit wiring, trunking systems,

distribution boards, switchgear,

control panels and electrical cabinets.

What standard does 6491B cable follow?

6491B cable is designed according to

BS7211 requirements and is also related

to BS EN 50525-3-41.

Is 6491B cable LSZH?

Yes. 6491B cable uses LSOH / LSZH

thermosetting insulation to help reduce

smoke emission and corrosive gas release

in the event of fire.

Is 6491B cable sheathed?

No. 6491B is generally a single core

insulated cable.

It is not normally described as a

sheathed power cable.

Is 6491B cable armoured?

No. 6491B is not an armoured cable.

It should be installed in conduit,

trunking, panels or other protected

wiring systems where mechanical protection

is required.

What is the difference between 6491B and 2491B?

6491B is commonly used for fixed wiring

and building wiring applications.

2491B is commonly used where greater

flexibility is required for panel wiring

and equipment wiring.

Where is 6491B cable commonly installed?

It is commonly installed in buildings,

public facilities, schools, hospitals,

airports, offices, control panels,

switchgear and distribution boards.

What information is required for quotation?

Please confirm voltage rating,

conductor size, conductor class,

insulation colour, cable length,

installation method and required standard.

Destination port or delivery address

is also required.
