The cubicle
The high voltage part of the cubicle is separated in 3 compartments using metal partitions (PM class):
- Busbars compartment
- Cables compartment
- Compartment for switching device
Each compartment is connected to earth. These partitions are defined Loss of Service Category class “LSC2B-PM” by IEC standard IEC 62271-200: 2011.
