Abstract (en)

[origin: WO2006103193A2] The invention relates to a transformer, in particular an entirely resin-impregnated transformer comprising at least one low-voltage coil and at least one high-voltage coil. The application of an electrical shielding around said high-voltage coil makes it possible to prevent a voltage disruptive discharge in such a way that the transformer external wall can be touched by a person and also provides the transformer with electromagnetic shielding. The inventive transformer is provided with through holes for internal electric connections and for this reason, it can be placed in media affected by dirty and in open air.
