CU/XLPE/OSCR/PVC/SWA/PVC-FR 500V to BS EN50288-7 IEC332-3-24
Application
Instrumentation cables are used in data processing and process control. The electrostatic screen protect the screened pairs against outer electrostatic interference fields. Low level of line attenuations and low mutual capacitances enable long transmission distances fast pulse accelerations. Steel wire armoured version are suitable for fixed installations in damp locations, in open spaces and for underground laying.
