Abstract: A transformer core is disclosed, which can include at least three hollow-cylindrical rectangular shaped core-discs wound from a magnetic band-like material, wherein two opposed limb areas and an upper and lower yoke area can be formed along a circumferential path. The core-discs can include one first and at least one second slanted area parallel to the circumferential path in the belonging limb area. The at least three core-discs can be connected according to a polygonal layout at their first slanted areas, which can be arranged adjacently face to face. Conical shaped polygonal adapter plates fitted to the polygonal layout within the upper and lower yoke areas, which can be clamped together.
