RE: Dry type Transformers
You need to cool oil down and that requires heat exchangers and such, a cast resin just pump in cool air and keep it cool.
For step up it generally involves larger powers say >10MW
Heat losses require better disposal of the heat. Also Power generators generally have a lot of switching operations going on and dry types dont really like being switched on when connected - both step up and step down.
Just from what Ive heard and seen but then again I may be deluded !
