BS6724 three core LSZH armoured cable
is designed for fixed low voltage
power distribution.
It is suitable for buildings,
infrastructure projects, industrial facilities,
public utilities, plant rooms
and protected power distribution systems.
The cable uses stranded copper conductors
for reliable electrical performance
and practical installation.
The XLPE insulation provides good
electrical performance and thermal stability.
The LSZH sheath helps reduce smoke emission
and corrosive gas release in the event of fire.
The steel wire armoured construction
provides mechanical protection for
demanding installation routes.
This cable is commonly installed on cable trays,
in ducts, in risers, in plant rooms
and in protected underground routes.
Three core construction is commonly used
for three-phase low voltage power circuits
and general power distribution systems.
It is suitable for applications where
low smoke zero halogen performance,
mechanical protection and fixed installation
are required.
The cable should be selected according to
voltage rating, number of cores,
conductor size, conductor material,
armour type, installation method
and project specification.
