Application

These cables are used for intrinsically safe circuits. For hazard prone areas cables with blue sheath are used for controlling and measuring requirements.
These installations are not earthed and require a seperate power circuit.
Tinned copper braid screen ensures disturbance free transmission of data and signals.
