Similar in construction to the BS 6883 657 SW4 instrumentation types, these cables have an additional steel wire braid armour for mechanical protection. Manufactured in both pairs and triples these 150/250V marine instrumentation cables provide collective or individual screening through the use of metallic foils and drain wires. They maintain good flexibility for installation on ships and oil rigs. The SW4 Low Smoke Halogen Free sheathing is oil resistant and ensures that in the event of a fire the cable will offer excellent protection to both people and property by not emitting toxic or corrosive gases.
