APPLICATION

The Airprot cables 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.
