Abstract

The disclosure relates to an amorphous transformer core including at least one transformer core disc with a plurality of layers of strip-like amorphous core material arranged concentrically around at least one winding window. At least one heat dissipating plate extends into an interior of the amorphous transformer core and is fed from there into at least one heat exchange region outside the amorphous transformer core. This can enhance dissipation of heat energy which is produced inside the amorphous transformer core.
