16 MVA and 72,5 kV and above, oil-immersed transformers are described as Power Transformers. Power transformers require distinct expertise and experience in particularly insulation and cooling issues.

Enmaksan is capable of designing, manufacturing and testing power transformers up to 1250MVA, 765kV with its modern plants thanks to 50 years domestic and international experience. Although they essentially have similar structure, particularly the differences in customer requirements and specifications call for new design for each transformer.

Therefore, Enmaksan Electrical and Mechanical design groups handle each transformer separately. Enmaksan manufactures power transformers that meet every requirement in every power and voltage range above 16MVA.
