Abstract (en)
The invention relates to a method for manufacture of cores for three phase transformer (10) whereas the core (14) is composed of three frames (16) designed to be combined so that each transformer core leg (18) is composed of two frame legs (18), whereas the transformer core legs (16) are arranged in a triangular configuration, and the cross-section of the core legs (20) have a circular or polygonal shape, and where the core frames (16) are made of layers of at least one continuously wound band (22) of low-loss magnetic material, whereas the width of the bands (22) is adjusted according to the respective layer of the core leg (20) by means of laser (24) cutting.
