APPLICATION
BS6724 single core LSZH armoured cable is used for fixed power distribution.
It is suitable for buildings, infrastructure, data centres, hospitals, transport systems and industrial projects.
The cable is designed for installations where low smoke, zero halogen performance and mechanical protection are required.
For single core AC systems, aluminium wire armour is commonly used to reduce magnetic losses.
