BSC143 type multi-pair instrumentation cable

BSC143 type multi-pair instrumentation cable is designed for the transmission of analogue and digital signals in instrument and control systems.  The collective aluminium/polyester tape (CAT) screen provides protection against electrical interference. The steel wire armour (SWA) provides protection against mechanical damage.

Manufactured generally in accordance to British Steel standard BSC143 they can be used in Group II classified areas of zones 1 and 2 (IEC 60079-14). 

These cables are not suitable for direct connection to the public mains supply.

Polyvinylchloride (PVC) Properties: These compounds are self-extinguishing with fair abrasive resistance, good resistance to water, aqueous salt solutions, acids and alkalis.
