In our time VPI dry type transformer, cast-coil ,cast-resin and resin encapsulated are basically the same
thing as the procedure is based always on Vacuum Pressure Impregnation using more or less the same epoxy resin -Araldite or else and the result is cast-resin coil.
Some fiberglass reinforcement is provided also.
The resin encapsulated is a transformer encapsulated in a metallic envelope and could be simple or double insulated according to application request.
On the web you may find infinite number of articles explaining the technology. For instance:
