Dry Type Transformer

Dry Type  Transformerare those transformers that utilization air as cooling and dielectric medium rather than regular innovation of transformers which utilizes mineral oil as a cooling and dielectric medium.

Cast Resin Dry Type Distribution Transformer

The loops of Cast Resin Transformers are casted in epoxy under vacuum in a shape to frame a void free inflexible throwing over the curl. These transformers are utilized in establishment like steel and concrete plants just as swarmed and urban regions, inside the premises of a private and business building.

We at Vidyut Transformers have a modernized Casting plant to make Cast Resin transformers upto 3 mVA 33kV Class.
