ApplicationThese 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.
StandardAdapted to DIN EN 60079-14: VDE 0165 Part 1.
