Power Transformers are designed and manufactured in accordance with the national and international standards (IEC, IEEE, etc.) according to customer requirements at 5000 kVA and 72.5 kV voltage level and above. Power transformers have a wide range of technical characteristics such as power, voltage, regulation. Power transformers are used in electricity transmission lines, industrial plants, power generation centers and electrical internal needs.

TT, has a production capacity up to 800 kV voltage level up to 1000 MVA, has completed the production of 125 MVA power transformer prototype at 400 kV voltage level in 2018 with the R & D Center studies and sent to KEMA for short circuit mechanical strength test.
