Oil-immersed power transformers

They are produced in single-phase and three-phase versions, in voltage classes 6-150kV and in power range 1,25-63000kVA.
Almost any of the transformers presented in this section can be made in the railway performance when HV winding (for transformers voltage class 27,5-35kV) or MV winding (for transformers voltage class 110-150kV) performed at 27,5 kV instead of 35 kV.
In this case, the letter "Ж" should be added to the transformers marking, e.g. ОМЖ, ТМЖ, ТДТНЖ etc.
