Abstract

A dry-type transformer includes at least one high-voltage winding and one low-voltage winding. The windings are operatively connected to one another by an electromagnetic field, and each winding is constructed from winding conductors, wherein the high-voltage winding and the low-voltage winding have a defined distance from one another, and spacers are arranged between the windings and maintain the defined distance.
