Abstract: The invention is related to a wound transformer core (10, 66, 82) with at least one core loop (12, 14) made of magnetic material, comprising multiple thin amorphous band-like iron sheets (16) which are concentrically stacked around at least one center axis (18, 20). A lower yoke section (24), an upper yoke section (22) and at least two limb sections (26, 28, 30) are developed, comprising a modular plate-like support structure (40, 74, 76) which is glued upright to the center axis (18, 20) on both face sides (70, 72) of the lower yoke section (24) and on both face sides (70, 72) of each limb section (26, 28, 30) in that way, that neighboured iron sheets are glued together at their outer edge. The modular plate-like support structure (40, 74, 76) comprises for each face side (70, 72) of the belonging core sections (24, 26, 28, 30) at least two plate-like modules (42, 44, 46, 48, 50, 86, 88, 90), which are connected each to each other by a first (100) or second (110) plug-in connection..
