ABSTRACT:
A distribution transformer has a wound magnetic core (50) of overall circular shape and rectangular cross-section with between two and four overall rectangular shape electric coils (20,30) extending through the core window. The coils (20,30) are pre-formed and assembled so that their parts (20A,30A) which meet form a circular section solid cylinder. A mandrel (40) is then located around this cylinder (20A,30A) and continuous non-amorphous steel strip is wound thereon to form an unannealed, uncut wound magnetic core of axial length in the range 250 mm to 1 m. In a modification, amorphous steel strip is first wound on to another mandrel, annealed, and then transferred from the other mandrel on to the mandrel around the coils.
