    Abstract: The invention is related to an on-load tap-changer (10, 40, 60, 80) for dry transformers, comprising an electric insulating hollow casing (12, 62) extending around a virtual axis (14, 70), wherein several electric contact sections (16, 18, 20, 22) are foreseen along the inner surface of the hollow casing (12, 62), which are electrically joined through the wall of the hollow casing (12, 62) and a selector contact in the inner of the casing which is rotatable around the virtual axis and that's radial outer end is selectively connectable with one of the contact sections by a respective rotation. The inner space (30) of the hollow casing (12, 62) is hermetically sealed and filled with a preferably pressured insulating gas. The invention is also related to a transformer with an on-load tap-changer (10, 40, 60, 80).

    Abstract: The invention is related to a dry transformer (10), comprising at least one hollow-cylindrical resin casted coil (12, 14) and a transformer core (16, 46) extending at least in part there through, wherein support elements (18, 26) are foreseen to carry the weight of the resin casted coil (12, 14) to the transformer core (16) respectively to mounting elements (20) connected therewith. The support elements (18, 26) comprise damping material at least in a section so that transmission of vibrations of the transformer core (16, 46) to the resin casted coil (12, 14) is damped.
