The transformer oil processing plant ELMO-UVM-6/12

The Plants are designed for heating, degasation, drying and filtration of the transformers oils which is used in the oil-filled electrical equipment (for example, power transformers) up to 1150 kV. The Plants can also be used for heating the electrical apparatus by the hot oil.

The Plants are intended for application by installation, repair, and operating organizations involved in processing of liquid and hard insulation of oil-filled electric apparatuses.
