300/500V single core XLPE insulated
LSZH sheathed cable to BS7211 is designed
for fixed wiring and low voltage
building installations.
It is suitable for commercial buildings,
public facilities, hospitals, airports,
schools, data centres and transport systems.
The cable is used where low smoke
zero halogen performance is required
to reduce smoke emission and corrosive gas
release in the event of fire.
The XLPE insulation provides reliable
electrical performance and thermal stability.
The LSZH outer sheath provides low smoke
and halogen free performance for safer
indoor installation environments.
This cable is commonly used for lighting,
power, panel wiring and general fixed wiring
circuits in buildings.
As an unarmoured single core cable,
it should be installed where mechanical
protection is provided by conduit,
trunking, cable tray or other protected
wiring systems.
The cable should be selected according to
voltage rating, conductor size,
insulation colour, sheath colour,
installation method, fire performance
requirement and project specification.
