The State-of-the-art production facility for manufacturing of  high quality power transformers with a capacity of up to 800 MVA and with a voltage level of up to 525 kV.

The plant is equipped with the world class modern equipment and production lines from the leading global companies such as SAGMA, GEORG and HEDRIC. The production buildings are equipped with DEMAG overhead cranes with a load capacity of up to 300 tons, as well as air-cushion support that can move components weighing up to 500 tons.

In addition to the automatic lines for the main production, the plant has also equipment for pre-drying and crimping windings and individual transformer components in automatic mode which increases the electrical resistance of the insulation. Powerful vacuum furnaces for drying active parts of transformers in solvent vapors which help significantly reduce the drying time and improve the quality of products.

In addition to large-size power transformers, the plant has also mastered the production of current and voltage measuring transformers from 110 kV to 220 kV. A modern test laboratory built by the German company HIGH VOLT allows to carry out all necessary tests with high accuracy which, in the end, guarantees that all parameters of the products meet the standards.

ATEF Elektromash Plant has a historical significance and rich production traditions for the ATEF company. It began to function as Baku Dry Transformer Plant which was founded in 1961.

After privatization in 1992, the company restored production, and after modernization in 2003 the plant received its current name, ATEF.

ATEF Elektromash Plant specializes in the production of oil immersed and cast-resin dry-type distribution transformers, CTS (complete transformer substations), as well as metal supports for power lines and railway, etc. The plant operates a number of important units and sites for the localization of components of the final products which serve to support the domestic energy industry and the export of products. The plant also has a testing laboratory where transformers are tested in accordance with the international standards.

Such units as a textolite shop, a rubber shop, a plating shop, a paint shop, an optional equipment shop, a packaging shop and others allow to shorten the time and reduce the cost of transportation of components for main production.

One of the most important enterprises of ATEF Group of Companies is Casting Products Plant. Aluminium, copper and steel castings are made here. The activities of the enterprise comply with all environmental regulations.

There is a wide range of manufactured parts from steel, aluminium, copper, bronze, brass, other metals and alloys. All the parts for the railway contact network, linear fittings of power transmission lines, elements of rigid busbars and open switchgears are manufactured by casting or hot forming.

The plant applies the technology of mold, sand casting as well as casting under low and high pressure. The company has installed ITALPRESS and ALU-03, TERMOLIT melting furnaces.

In parallel with the traditional casting techniques, we have also mastered evaporative-pattern casting (EPC) which allows the company:

- Reduce the cost of subsequent mechanical treatment
- Ensure stable quality of casting
- Quickly produce parts with complex configurations
- Ensure compact production and reduce emissions of toxic gases

At the present time, in developed countries, 30% of all casting is done by this method. EPC is almost waste-free and does not require a large number of related materials in the form of various resins. 

The plant also produces rectangular and tubular copper and aluminium busbars, i.e. insulated. According to the requirement of the customer, it is possible to manufacture busbars of various configurations.

To ensure timely and high-quality configuration of transformer plants of ATEF Group of Companies, the specialized Insulation & Component Plant was built and put into operation in 2018. 

The enterprise manufactures hard insulating parts made of electric cardboard and wood-laminated plastic based on thickened beech veneer (TBV), produces uniforms for company employees, cabinet and soft furniture, the products such as PVC doors and windows for various projects.

The plant produces all types of insulation parts for power and distribution transformers. For this purpose, the plant has installed high pressure presses and modern drying and processing lines. Special multi-axis programmed machines quickly and accurately cut the most complex configurations of insulation parts, as well as forming and pressing machines are able to produce cylinders and rings of any diameter.

As it is known, the reliability and durability of power dry-type distribution transformers and reactors depends significantly on the perfection of the insulation system in the active part, particularly on the correctness of the design of the parts and the quality of the insulating materials. In the design of power high-voltage transformers, the hard insulation is about 7-8% of the transformer total mass. 

This includes the following:

- Winding cylinders
- Pressing rings
- Capacitive rings
- Remote seal gaskets
- Stairs for the magnetic circuit paces
- High voltage hoses and drains
- Straight and reverse angle washers 
- Insulation threaded studs and screws
- Crepe paper tubes, ect.
