CBMV station is built for 24kV maximum high voltage and has two variants:
SFL-6600 20kV transformer supporting 19kV - 21kV range for High Voltage side
SFL-6600 21 kV transformer supporting 20kV - 22kV range for High Voltage side
Both versions can be used at 20kV or 21kV.
Factory setting
CBMV is set the factory to 20 kV or 21 kV. This setting can be changed during installation by our commissioning engineers if required.
