Abstract (en)

[origin: WO2017140482A1] The invention relates to an electric winding for a dry-type transformer that makes it possible to build a compact dry-type transformer even for higher voltage classes. To this end, the electric winding includes a plurality of windings of a winding conductor that are wound so as to form a coil. The coil is embedded in a solid insulator. According to the invention, a coating made of an electroconductive material that comprises a resin matrix and microscale filler is applied to at least one surface of the insulator.
