Shipwiring/Offshore Screened
Instrumentation Cables to BS6883
(Ref. 658 SW4 Instrumentation)

Manufactured in both pairs and triples these 150/250V instrumentation cables provide collective or individual screening through the use of metallic foils and drain wires. Offering good flexibility for installation in confined spaces or where difficult routing is necessary, the galvanised steel wire braid provides mechanical protection.

The latest SW4 Low Smoke Halogen Free sheathing compounds are used to ensure that in the event of a fire the cables offer excellent protection to both people and property by not emitting toxic or corrosive gases.

Cable Construction -
Collectively screened

Tinned copper wire conductors to BS 6360, class 2 or class 5, EPR insulation, cores twisted into pairs or triples, overall foil screen and a tinned copper drain wire, LSHF inner sheath, galvanised steel wire braid, SW4 LSHF outer sheath - grey or blue.

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'!

Fire retardant, fire resistant, flame resistant or flame retardant?

These terms are often misunderstood. Most cables when exposed to fire will not carry on functioning. If you require cable to continue working in the event of fire, and in accordance with various standards please call us.
