Distribution transformers are used in the last leg of Power distribution to feed electricity to residential, industrial and bulk consumers. Transformers with primary voltage of 11 kV and below are termed as Distribution Transformers. We at Shri Ram Group Of Industries have a huge integrated facility to manufacture Oil cooled Distribution Transformers.
