Our history

Electrozavod JSC joined AFK Sistema. ERSO, Russia's leading holding company for manufacturing and supplying electrical equipment and providing comprehensive services with a focus on international leadership, was established

In 2010, a new milestone of Russian transformer engineering was reached: Electrozavod mastered the production of powerful power transformers for ultra-high voltage of 750 kV. The first 417 MVA transformer of this voltage was produced for Kalinin NPP.

To reduce electric power losses through effective reactive power control in electrical networks as well as to maintain stable voltage on substation buses, 180 MVA controlled shunt reactor with 500 kV voltage was designed and manufactured.

Research and new developments are performed for transformer and reactor equipment, gas-insulated switching equipment, complete switchgears of medium voltage class and converter devices for the power industry, which are unique in their characteristics.

Development of distribution transformers with magnetic cores made of amorphous steel, which allows to reduce no-load losses of transformers by four times, is in progress.

In 2004, the Ufa Plant Electroapparat joined ELECTROZAVOD OJSC.

At the end of 2005, the foundation stone for the new Ufa Transformer Plant was laid, which the company started to build. The President and Prime Minister of the Government of the Republic of Bashkortostan took part in the ceremony.

In 2008 joint venture "Moskabel-Electrozavod" was established with the main activity: production of transposed and enameled wires intended for manufacturing of transformer windings, high-power reactors.
Transformers and autotransformers were developed and mastered in production:

- for power systems of the Western direction and the Caucasus with a voltage of 330 kV;
- for Kursk NPP a 630 MVA transformer TC-630000/330, the most powerful of all the transformers manufactured in Russia before, was produced.
In 2009, the new Ufa plant Elektroapparat was put into operation. Vladimir Putin took part in the ceremonial launch.

The Electrotechnical Institute of Innovative Technologies was created.

New types of transformer equipment with increased reliability are mastered: autotransformers up to 267 MVA for connection of 500, 220 and 110 kV power grids; generator transformers up to 400 MVA for 220 and 500 kV for power plants with powerful power units; new three-winding 110 kV transformers for distribution substations; designs of 500 kV shunt reactors are improved, 110 MVA, 750 kV reactor is developed, improved voltage and current measuring transformers with increased accuracy.

Equipment for the largest start-ups in the country is supplied, including: shunt reactors for nuclear power plants being commissioned, powerful transformers for the Kama Automobile Plant, Novgorod Production Association "Azot", Orenburg Gas Processing Plant, Novo-Sterlitomakskaya TPP.

The plant developed and delivered "shock transformers" with capacity of 70 and 90 MVA for 110, 150 and 220 kV for test centers, and a series of arc-suppression coils with stepless inductance control.

At the entrance to the Automotive Electric Equipment Plant-1 monument to the plant workers who fought at the front and worked on the home front is installed. Architect S.P. Buritsky, sculptor V.N. Levin.

Transformer and reactor equipment for the first 800 kV Volgograd-Donbass DC power line, and then for the 1500 kV power line is being produced. The most powerful 300 MVA shunt reactor was manufactured to provide long-distance transmission of enormous power capacities along super high-voltage 1150 kV Ekibastuz-Center AC power line.

The plant supplies equipment for the most important start-up facilities ahead of schedule, including powerful 110 and 220 kV three-phase transformers for Kuibyshev Production Association "Azot", Cherepovets Metallurgical Plant, etc.

In 1977, a powerful transformer ТРДЦН-80000/110 was produced for the Kama Automobile Plant.

Transformer and reactor equipment for the first 800 kV Volgograd-Donbass DC power line, and then for the 1500 kV power line is being produced.

The most powerful 300 MVA shunt reactor was manufactured to provide long-distance transmission of enormous power capacities along super high-voltage 1150 kV Ekibastuz-Center AC power line.

The development and mastering of production of powerful electric furnace transformers at 110 and 220 kV with voltage regulation under load for ore-thermal furnaces is carried out.

The plant supplies equipment for the most important start-up facilities ahead of schedule, including powerful 110 and 220 kV three-phase transformers for Kuibyshev Production Association ""Azot"", Cherepovets Metallurgical Plant, etc.

November 5, 1968 took place the grand opening of the memorial "To the Heroes of the Electrozavod Plant from the staff of the plant 1941 - 1945". On marble plaques mounted on a high brick stele, 114 names of workers and employees of the Moscow Electrozavod named after V.V. Kuibyshev were carved. In front of the stele on the right side is set concrete sculptural group with a girl escorting a soldier to the front.

Powerful shunt reactors under 500 kV voltage for power lines, transformers for electric arc furnaces, and complete transformer substations are being developed and manufactured.

Unique equipment for 750 kV overvoltage AC power lines connecting the power systems of Siberia, the Urals, the European part of Russia and Eastern Europe: shunt reactors, measuring voltage transformers of capacitive type, high-frequency arresters are being developed.

The new 110 kV transformers were the first transformer equipment to receive the "Quality Mark" for high technical and economic characteristics.

Equipment is developed and supplied to the most important facilities and new buildings of developing power and industry, including Kuibyshev, Stalingrad, Irkutsk, Gorky, Karakum HPP, Chelyabinsk, Bratsk, Konakovo power plants, equipment for Magnitogorsk, Taishet and Verkh-Isetsk metallurgical plants, Nikopol Ferroalloy Plant, Bratsk Aluminum Plant and many others.

Serial production of a wide range of transformers with special operating requirements for equipping ships and submarines is being mastered.

The first autotransformers, which were widely used in power systems for connection of 110, 220, 400 and 500 kV networks, are being developed and organized for production.

Many years of research and design work to create a set of 400 kV transformer equipment for the Kuibyshevskaya HPP-Moscow line (jointly with the Zagorsky Pipe Plant and All-Russian electrotechnical institute) resulted in the production of fundamentally new equipment. The complex included 400 kV transformers, transformer units for regulation under load, shunt reactors for compensation of capacitive currents in the line. The development and mastering in production of 400 kV electrical equipment was recognized by the country with the State Prize.

In 1954, a bridge across the Yauza River was named after Electrozavod Plant - Electrozavodsky Bridge, built according to the design of engineers Y. F. Werner, S. M. Zamyatin and architect S. P. Leontovich.

In the post-war years, the output of transformer equipment at the plant exceeded the pre-war level several times over. Electrozavod produced transformers for construction of the "Moscow-Volga" canal, for the Moscow Metro, Moscow high-rise buildings, the Ostankino TV tower, the Palace of Congresses in the Kremlin.

For the first time in the domestic practice, powerful autotransformers were developed for high-voltage power grid connection and tested at a number of 220 kV and 110 kV substations as well as at Kuibyshevskaya HPP for connection of 500 and 220 kV systems.

The experience accumulated by the Electrozavod workers is used in designing, construction and organization of production of transformers at the newly created plants in the Urals and Ukraine.

Three produced transformers with a total capacity of 60 thousand kilovolt-amperes for Svirskaya HPP allowed to restore the operation of the power plant. The plant also produced several powerful transformers for Stalinogorskaya SDPP, Rybinskaya SDPP and a number of new buildings.

At the same time, until the beginning of the 1950s, the plant buildings and Electrozavodskaya Street were repeatedly flooded by flood waters of the Yauza River and its tributary Khapilovka, which was later encased in a pipe.

During the Great Patriotic War the workshops were switched to a double-shift mode of operation - 11 hours each shift. They worked without days off. In addition to the main products the plant staff fulfilled the defense order: special transformers for the forced entry-resistant constructions, antitank hedgehogs, mine detectors. The plant supplied assemblies for "Katyusha" Guards mortars and projectiles for them. T-34 tanks which went straight from the factory gates to combat positions were repaired in the shops.

320 workers of Electrozavod made up the core of militia division of Kuibyshevsky district of Moscow, and all in all 1200 people went to the front from the plant.

In 1944, a metro station was named after Electrozavod. On the walls of the ticket hall of "Electrozavodskaya" station there are medallions with portraits of scientists-founders of electrical engineering: Lomonosov, Yablochkov, Popov, Faraday, Franklin, Hilbert, and in the central station hall there are 12 bas-reliefs with images of workers.

On April 22, 1938, by order of the People's Commissariat of Mechanical Engineering, the Moscow Electrokombinat was divided into four independent plants: the Kuibyshev Moscow Transformer Plant, the Automotive Electric Equipment Plant, the Moscow Electric Lamp Plant and the Moscow Machine Building Plant.

In October 1938 the Electrozavod plant developed a concrete reactor (РБ-64000/115) for Butyr substation in Moscow. The tests of the first prototype of such reactor were successful and from that moment the serial production of current-limiting reactors was organized.

On April 21, 1939 Electrozavod was awarded the Order of the Red Banner of Labour "for outstanding and selfless work at power plants, successful organization of Stakhanov movement and mastering of new types of power equipment at electrical industry enterprises" by the Decree of the Presidium of the Supreme Soviet of the USSR.

Designs of complex "lightning-proof" high-voltage transformers with voltage regulation under load were developed and mastered to connect disparate power plants by high-voltage transmission lines into power systems, transformers to power electric furnaces, 220 kV voltage measuring transformers, (made by cascades in porcelain covers) and the first lines of the Moscow subway.

In 1936 the engineers S.Rabinovich, B.Gelperin, E.Mankin created a design of a powerful 40 thousand kilovolt-ampere transformer for 220 kV voltage for Zuevskaya SDPP. Development was completed and production for the Dnieper-Donbass system of 220 kilovolt transformer with 40 thousand kilovolt-amperes in one phase was started.

Electrozavod started manufacturing high-voltage transformers for the "Volga-Moscow" channel.

For the country's first 220 kV power transmission line Svirskaya HPP - Leningrad, the plant designed and manufactured 9 single-phase transformers (3x46 MVA), which were the most powerful in pre-war years.

A group of engineers headed by A. Sapozhnikov developed a design of test transformer for 300 kV. For the first time the plant manufactured a transformer of OMT-20000/220 type for Stalinogorskaya HPP and a regulating unit (booster) for Tula metal works.

The Electrozavod provided transformers for dozens of power plants being built and reconstructed under the GOELRO plan, major construction projects of the country, including DneproGES, Magnitostroy, Uralmashstroy, Gorky Automobile Plant, Kharkov, Stalingrad and Chelyabinsk tractor plants, Saratov Combine Plant, Donbasstroy, the first electrified section of the Transcaucasian railroad.

In terms of output the plant became the largest of the electrical engineering enterprises in Europe.

On April 9, 1931, Electrozavod was awarded the second Order of Lenin for fulfilling the five-year plan in two and a half years. Fifteen employees of the Electrozavod were also awarded the Order of Lenin for particularly outstanding services.

In June 1931 Electrozavod together with the "All-Russian Electrotechnical Institute named after V.I. Lenin" (now "Russian Federal Nuclear Center — All-Russian Research Institute of technical Physics named after Academician E.I. Zabababakhin"), a special department was established, which prepared the specialists necessary for transformer construction, electrical engineers.

In July 1931 George Bernard Shaw visited the USSR. In the Soviet Union the great playwright and his companions received a warm welcome and a rich cultural program. The Kremlin, Lenin's Mausoleum, the Park of Culture and Recreation, a car trip around the city, a "production tour" at the Moscow Electrozavod where the writer talked with the workers and separately with the literary circles, and finally a large-scale celebration of Bernard Shaw's 75th birthday in the Columned Hall of the House of Unions.

Poet Vladimir Mayakovsky wrote eight slogans dedicated to the Electrozavod and its workers, including the slogan:
«Sweep away the slackers and lazybones!
Let's get work of the highest quality!»

In the same year, Vladimir Mayakovsky dedicated his famous "March of shock brigades" to the Electrozavod workers. This march was first published on January 14, 1930 in a factory newspaper, and then included in the poet's collection.

In different years and on different occasions prominent figures of Soviet literature came to the plant: L. Leonov, F. Gladkov, A. Novikov-Priboy, M. Shaginyan, L. Seifullina, K. Paustovsky, V. Lidin, A. Karavaeva, A. Gaidar and others, and Alexey Maksimovich Gorky was enrolled at the plant as an honorary welder.

T.S. Lennox, a consulting engineer from "General Electric" company (GE, USA), who had worked at the Plant until 1933 and had contributed much to the training of engineers and establishment of the Plant, came to the Plant. In the photo Lennox surrounded by engineers and future designers of the plant. Standing: K. Brekhov, V. Yastrebov, A. Trostyansky, A. Menis, G. Spuv, E. Balashov, A. Sapozhnikov, sitting: B. Gelperin, S. Rabinovich, T. Lennox, A. Koritsky, L. Schnitzer, J. Kronhaus.

On September 30, 1930 in the Bolshoy Theater a gala evening of shock workers of Electrozavod was held.

On October 3, 1930, the plant was awarded the Order of Lenin for its dedicated patronage work on the line of the State Association of Soviet Grain Farms.

Generalnaya Street was renamed Electrozavodskaya. This happened at the request of Electrozavod workers, who sent a collective appeal to the Moscow Soviet at the official celebration dedicated to the launch of the Plant in 1928.

In 1929 transformer builders produced nearly 7 million rubles worth of products instead of 4 million rubles according to the state plan (the number of employees of the plant was 6700 people).

The first domestic designs were developed and production of 35 and 110 kV transformers, surpassing their German counterparts in terms of main technical characteristics, was mastered. The most powerful 5,600 kVA 35 kV transformer was smaller in size than the German one, saving up to 40% of scarce nonferrous metals and transformer oil.

On November 4, 1928, GET Electrozavod was officially started up with the participation of V. V. Kuibyshev, Chairman of the Supreme Council of National Economy.

At that time, Electrozavod GET consisted of the 1st and 2nd State Electric Bulb Factories, the "Projector" plant, the "Metal" plant, and the "Transformer" plant.

The "Transformer" plant began serial production of domestic 6 kV and 10 kV transformers with a capacity from 10 to 160 kVA.

It should be noted that in fact the plant began experimental production as early as in 1927, and by the end of 1928 the volume of production was 9 million.

The very first transformer, produced at Generalnaya Street, was branded TM-10/6. Soon the plant began to develop new types of transformers for 200, 250 and 320 kilovolt amperes, putting them into serial production. The plant began to receive its first orders.

A four-kilometer branch railway line was built from Cherkizovo-Sortirovochnaya Station to Electrozavod, which became one of the first electrified railroads in the USSR. To service it, four electric locomotives GET were assembled at "Dinamo" plant, one of which later became an exhibit in the Railway Museum at the Varshavsky Station in Saint Petersburg. Diesel locomotives ТГМ1, ТГМ23В, ТГМ40 and ЧМЭ2 were also used on the line.

At the end of 1925, the State Electro-Technical Trust (GET) decided to build a specialized transformer plant. The construction site was chosen in Moscow, on the territory of the "Provodnik" plant.

In May 1926, the board of the State Electro-Technical Trust approved the design of the plant, which was named "Transformer" GET. Nikolai Aleksandrovich Iuganov, a Soviet economic activist, was appointed head of the future plant and its construction. N.A. Iuganov received information about the appointment personally from F.I. Dzerzhinsky. Prior to his appointment, Iuganov worked as director of the Moscow "Metalist" plant.

At the time of official commissioning (1928), N.A. Iuganov, being seriously ill, at his own request, took the position of deputy director, and Nikolai Aleksandrovich Bulganin was appointed the new director of the plant.

N.A. Iuganov was one of the first to be awarded the Order of Lenin (1931) for his outstanding work achievements.

In 1920, under V. I. Lenin's assignment and guidance, the State Commission for Electrification of Russia (GOELRO) plan was developed. It was to last 10-15 years, providing for restoration and reconstruction of old electrical and power enterprises, construction of new large enterprises, construction of 30 regional power plants (20 thermal electric power stations and 10 hydroelectric power stations) with total capacity of 1750 thousand kilowatts.

In October 30, 1921 by resolution of the Supreme Council of National Economy the General Directorate of the Electrical Industry (GLAVELECTRO) was established. Its head was appointed Valerian Kuibyshev, an outstanding statesman and party figure.

Name of V. V. Kuibyshev is connected with many pages of history of Electrozavod. Under his leadership the first power plants were built: Kashirskaya, Shaturskaya, Volkhovskaya, Balakhninskaya and others.

In Moscow, not far from the mouth of the Khapilovka River, the factory "Provodnik" of the Association of Russian-French factories, which produced rubber and caoutchouc products such as car tires, technical and medical products, was founded, and its branches and stores were located throughout Russia. Architect Georgy Pavlovich Yevlanov was the author of the Provodnik factory building. The factory was conceived as a Gothic castle with rose windows and tall towers modeled on medieval town halls, but due to the revolution, construction was discontinued.

Later the building was completed by the architect G.S. Shikhanov in a simplified form, without complicated Gothic decorations. However, the red-brick two-tower facade with rose windows became the hallmark of the factory, which in Soviet times was called a fortress factory.
