BS 6883 Shipwiring Instrumentation 657 SW4 Unarmoured

Designed for control and signalling, BS 6883 instrumentation cables are manufactured in pairs and triples with individual or collective screening.

The unarmoured flexible design of BS6883 657 SW4 allows for easy routing in confined spaces whilst the SW4 Low Smoke Halogen Free sheathing compound ensures the personnel safety in the event of a fire.
