Application
The cables are used to transmit signals and measured values in symmetrical circuits in control and regulation technology, as well as to transmit information in data and process computer systems. Suitable for flexible use and fixed installation in dry and damp rooms in and under plaster, but also for fixed installation on external walls of buildings. With blue outer sheath for intrinsically safe systems. Installation cables are not approved for high-voltage installation purposes or for underground installation.
