Armoured Shipwiring/Offshore Cables to BS7917 (Ref.658M SW4)

Used extensively for power and control applications on ships and oil/gas platforms where mechanical protection and fire resistance to IEC60331 is required. In the event of a fire these cables provide circuit integrity, produce minimal smoke and poisonous gas emission and are flame retardant to IEC60332-3A. These cables are also used for onshore applications where their combination of special properties make them ideal for essential services.

Cable Construction

Tinned copper wire conductors to BS 6360, class 2 or class 5, Mica glass tape, EPR insulation, LSHF inner sheath, Galvanised Steel Wire Braid, SW4 LSHF sheath - black.
      
Single core cables are armoured with phosphor bronze wires and are often referred to as 659* types.

At FSC we refer to LSHF as Low Smoke Halogen Free

This term is interchangeable with LSZH (Low Smoke Zero Halogen), LSOH (Low Smoke Zero Halogen), OHLS (Zero Halogen Low Smoke) and FRNC (Flame Retardant Non-Corrosive). Beware of the terms LSF (Low Smoke and Fume) or RP (Reduced Propogation), when relating to signal or control cables will normally be modified PVC and produce 'Loads of Smoke and Fume'!
