INSTRUMENTATION CABLES, EN 50288-7MULTI-PAIR, PVC INSULATED, INDIVIDUAL & COLLECTİVE SCREENED, ARMOURED, PVC SHEATHED These cables are used for transmission of analoge and digital signals in instrument and control systems at chemistry and petrochemistry industry plants, power plants, natural gas and petroluem plants, etc... . Instrumentation cables are not allowed for direct connection to a low impedance sources, e.g. public mains electricity supply. For application of 105oC heat resistant, RE-Yw(St)YwSWAYw-PIMF cables are suitable. With blue sheath it is suitable for intrinsically safe systems. The armour above the inner sheath protects the cable from mechanical shocks. These cables are recommended for direct burial. They are for indoor and outdoor installation, in dry and wet locations; on racks, trays, in conduits.
