PROBLEM TO BE SOLVED: To provide a transformer core which can be produced quickly by laminating steel sheets with guide slots formed at specific positions and, by filling the guide slots with lamination guides, have an improved stacking factor and reduce vibration noises that may be generated by the guide slots.SOLUTION: A transformer core 200 with a plurality of steel sheets 211, 221, 231, 241 laminated may include: at least one guide slot 211a, 221a, 231a, 241a formed on each surface of the plurality of steel sheets 211, 221, 231, 241; and lamination guides 250, 260, 270, 280 inserted into the guide slots 211a, 221a, 231a, 241a in the thickness direction of the transformer core 200 to join the plurality of steel sheets 211, 221, 231, 241.SELECTED DRAWING: Figure 1A |
