Zusammenfassung:A coil and electric shielding arrangement for a dry-type transformer includes an electric shielding device arranged at a distance from a winding, at an axial end of the winding perpendicular to a longitudinal axis of the transformer, and parallel to a top surface of a coil that is wound around the axis such that the electric shielding device covers a cross-sectional area of the winding perpendicular to the longitudinal axis. An insulation material attached to the winding and to the electric shielding device establishes a first distance between the winding and the electric shielding device along the longitudinal axis such that the winding is shielded against another electric field. The winding and the electric shielding device are casted in a block which insulates the electric shielding device from the electric field of the winding by establishing a second distance between the winding and the electric shielding device.
