      1942

      Based on the existing facilities, the "Electroshield" plant was organized, becoming the only enterprise in Central Asia producing power transformers, substations, electrical shields, and other electrical equipment. Equipment and personnel from the evacuated Leningrad plant "Electropult" were used in order to establish the plant.

      1995

      Serial production of transformers is mastered, including the creation of transformers for electric locomotives, mobile substations, and compact transformers.
