ABSTRACT:
An ebullition cooled transformer has a housing, a core and coil assembly disposed on the lower portion of the housing to be immersed into a condensible electrically insulating refrigerant, a cooler unit located above the core and coil assembly within the housing, and a communicating tube disposed at the top of the housing to communicate with the outside air and provided with a porous filter permitting the air to permeate it but preventing a vapor of the refrigerant from permeating it.
