Instrumentation control unarmored-armored cable. HR PVC/ XLPE Insulated, non screen/collective, screen armored/unarmored ST1/ST2/FR/FRLS/ZHFR.
Used in Indoor and outdoor insulation within industrial process plants and for controls power supply between instruments and process equipment.
Unarmored control cable are generally indoor use and armored cable are indoor as well as outdoor, in dry and wet locations, on racks, trays, in conduit,etc. armored cables are suitable for direct burial.
Selection of controls depends on instruments and process equipment, length between control room and process plants, surrounded temperature etc.
