BS 6724 Armoured Power Cables, 1900/3300V

Three-core 1900/3300 V cables with solid aluminum conductors

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.
