BS 7917 0.6/1kV Shipwiring Power Fire Resistant 657M SW4 Unarmoured

BS 7917 ship wiring cables provide fire resistance to IEC 60331, they are designed for use on ships and offshore installations where circuit integrity is vital to maintain services in the event of a fire.   

The unarmoured 657M SW4 versions are easy to route in confined spaces and along cable tray with tight bends. If there is risk of mechanical damage the braid armoured 658M SW4 versions provide good protection whilst maintaining flexibility.
