Transformers

摘要

A transformer comprises: a core formed from a plurality of planar laminations (11, 12) stacked together adjacent one another to lie substantially parallel; electrically insulating spacing means (13) provided between each of the laminations and a lamination adjacent thereto to separate them so as to provide a plurality of voids (14) in the core, each of which is between a lamination and a lamination adjacent thereto; and an electrically insulating fluid located within and filling said voids.
