Dry type transformers are those transformers that use air as cooling and dielectric medium instead of conventional technology of transformers which uses mineral oil as a cooling and dielectric medium.
Cast Resin Dry Type Distribution Transformer
The coils of Cast Resin Transformers are casted in epoxy under vacuum in a mould to form a void free rigid casting over the coil. These transformers are used in installation like steel and cement plants as well as crowded and urban areas, within the premises of a residential and commercial building.
We at Shri Ram Group Of Industries have a modernised Casting plant to manufacture Cast Resin transformers upto 3 mVA 33kV Class.
