Sub Merged Arc melting furnace transformers are manufactured in 3 phase system upto 12.5 MVA and Bank of 3 nos, single phase, transformers for higher than 12.5 MVA transformers.

The generator transformers have delta-connected LV windings energized by the generator voltage and star connected HV winding connected to the transmission grid. Easun MR make OLTCs are used to ensure robustness and longevity of the transformer.

Makpower supplies power transformers which transform energy from higher voltage levels and to distribute this energy to lower voltage substations or directly to large industrial consumers.
