Pairs Multistrand Copper Core PVC Insulation Copper Wire Braiding Individual Screen&Overall Screen Instrument Cable
Application of Instrument cable
The unarmoured versions (Part 2 Type 1) are generally use for indoor installation and suitable for wet
and damp areas. Generally used within industrial process manufacturing plants for communication, data
and voice transmission signals and services, Also used for the interconnection of electrical equipment
and instruments, typically in chemical or petrolchemical industry.
