Single & multi pair, HR PVC/PE/ XLPE Insulation, collectively/ individual pair and collectively screen, Unarmored/ Armored with G.I. wire/strip, PVC sheathed.
For transmission of analogue and digital signals in instruments and control systems.
Generally used within industrial processplants. Unarmored cables are generally for indoor applications and armored are for outdoor applications, in dry and wet locations, on racks, trays, in conduit,etc. Armored cables are suitable for direct burial.
Selection of cables depends on design, process, instruments, panels, equipment,etc and also on weather process conditions.
