In the rooms exposed to radiation i.e. hospitals, computer rooms, NYM(St) cables are used based on DIN VDE 0250-204/209.
The cables with a rated voltage of 450/750V and 750 V are intended to be placed permanently in power devices, in dry and wet rooms. They can be placed over and under plaster.

In addition, the standard PN-87/E-90056 specifies the parameters for YLY cables with a voltage of 0.6/1 kV. These cables are used in dry and wet rooms, especially steel structures, machinery bodies, in points particularly exposed to mechanical damage.
All types of cables from this group can be installed outside, but only if they are not exposed to direct sunlight.
