Abstract: The present disclosure relates to electrical windings for a dry transformer which allows construction of a compact dry transformer even in relatively high voltage classes. For this purpose, the electrical winding has multiple windings of a winding conductor wound to form a coil. The coil has been embedded into a solid insulation body. In some embodiments, a coating of an electrically conductive material, comprising a resin matrix with at least 0.05% by weight of nanoscale filler, has been applied to at least one surface of the insulation body.
