Abstract: The disclosure is related to a dry transformer, which includes a transformer core with at least two parallel limbs and upper and lower yokes, and at least two hollow cylindrical coils, each arranged as neighbored coils around a limb of the at least two parallel limbs. A cooling system can include at least one wall-like diaphragm in-between the neighbored coils, which is in parallel to the orientation of the limbs.

Abstract: 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.

Abstract: The present disclosure provides for the shielding of clamps of a transformer, and including an electric shielding arrangement for a transformer and a transformer with the arrangement. An electric shielding arrangement for a transformer is provided, with a clamp which is attached at a yoke and stabilizes the yoke of the transformer. The arrangement includes an electric shielding device arranged at the clamp between the yoke and a winding of the transformer and having a trough-like form. The electric shielding device may have the form of a rounded cover and is configured to shield the clamp from an electric field of the winding.
