HISTORY OF THE COMPANY

The history of the establishment of  “Chirchiq transformator zavodi” JSC begins in 1932, when the electromechanical workshops of the trust “Chirchikstroy” were established for the manufacturing and repairing of electrical equipment of the Chirchik hydroelectric power station and the nitrogen-fertilizer plant.

1942 -  on the basis of the electromechanical workshops of the “Chirchik-story” trust and the equipment and personnel of the evacuated plant “Electropult” from Leningrad, the “Electroshield” plant was organized, which became the only enterprise in Central Asia that produced during the years of wars electric boards, power transformers, substations and other electrical equipment.

 

1942. -  April 12, the plant was given the name "Electroshield".

1962 - The plant was renamed to Chirchik Transformer Factory.

1995 - With the independence of the Republic of Uzbekistan, the enterprise became a joint-stock company and was renamed into “Transformator” OJSC.

 

 

2001 - The enterprise was renamed “Transformator” JSC by the decision of the shareholders meeting.

2004 -  The state block of shares was sold, and the plant was transformed into a joint venture with foreign capital in the form of an open joint-stock company and again renamed to Chirchik Transformer Factory. In 2013 99.97% block of shares was transferred to the ownership of the State Committee of the Republic of Uzbekistan on privatization, demonopolization and development of competition.

2015 -  in the framework of the State Property Privatization Program for 2015-2016, in accordance with the Decree of the President of the Republic of Uzbekistan dated February 06, 2014. For No. N PP-2123, the state block of shares of JSC “Chirchiq transformator zavodi” in the amount of 99.5% is to be transferred to the initial charter capital of "Uzeltehsanoat" JSC

 

 

The history of the development of the products:
