what is the difference between dry type transformer and cast resin transformer?.or both are same?

A 'dry type' transformer is one in which the insulating medium is dry, not liquid.
A 'cast resin' transformer is one in which the insulating medium is a solid epoxy material. Therefore, 'cast resin' is one type of 'dry type' transformer.
There are also dry type transformers that use simple dry paper as the insulating medium.
