BS 6724 Armoured Power Cables, 1900/3300V

Applications :

  • 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.

Construction :

  • Conductor Solid Aluminum or Copper conductor, round stranded or shaped, Class 2 to BS 6460, IEC 60228.
    Insulation XLPE (Cross-Linked Polyethylene) Type GP 8 or ethylene propylene rubber (GP 6)
    Colour Code 1 Core : Brown
    3 Cores: Brown, Black, Grey
    Bedding LSOH (Low Smoke Zero Halogen)
    Armour Single Core: AWA (Aluminum Wire Armour)
    Multi Core: SWA (Steel Wire Armour)
    Outer Sheath LSOH (Low Smoke Zero Halogen)
