Three-phase transformers

Three-phase transformers

Three-phase oil transformers with output from 6,3 to 450 MVA, nominal voltage up to 420 kV.


ETD produce three-phase transformers by individual customer request with different type of the winding and special dimensions.

■ Three-phase regulating oil transformers with a power range of 10 to 320 MVA and nominal voltage up to 420 kV

■ Three-phase non-regulating oil transformers with an output up to 410 MVA and voltage up to 420 kV

Our transformers meet all new standards and regulations including ECO Design norms, which helps to reduce our Carbon Footprint globally!
