BS 6724 Cables
BS 6724 Armoured Power Cables, 1900/3300V
Single-core 1900/3300 V cables with circular stranded copper conductor
Application
These cables are used for power and control circuits, they can offer excellent protection through the use of a heavy galvanized steel wire armour. The GSWA makes them suitable for use inside and outside
buildings or for direct burial in the ground. For installation where fire, smoke emission and toxic fumes
create a potential threat to life and equipment.
