RE-Y(St)Y-PIMF
INSTRUMENTATION CABLES, BS 5308 PART 2 TYPE 1MULTİ-PAİR, PVC INSULATED, INDIVIDUAL & COLLECTİVE SCREENED, 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. These cables are not recommended for direct burial. They are for indoor and oudoor installation, in dry and wet locations; on racks, trays, in conduits.
