Data Sheet

Description

MODES OF OPERATION

The unit can be operated in the following modes:

  • oil heating and filtration
  • filtration, heating and thermo-vacuum oil purification
  • evacuation of transformer
  • pumping of oil

Benefits:

  • Drying, degassing and filtration of oil
  • On site drying of transformer with simultaneous treatment of the oil
  • First filling of electrical apparatuses with insulating oil
  • As option can be mounted on roadworthy trailer

APPLICATION

CMM systems serve for degasification, dehydration and filtration of transformer, cable, turbine and other oils for removal of gases, free and soluble water and particulate matter. The system is applied while installation, repair and operating of oil-filled high voltage equipment up to 1150 kV (power transformers, high-voltage switches etc.) as well as turbines.
