Winding assembly and method of its manufacture

摘要

A winding assembly (10) for a transformer includes a wire winding (7) and a sheet winding (1.3). The wire winding (7) includes a spirally wound insulated wire (6) and the sheet winding (1.3) includes a metallic winding sheet that forms a single turn winding. Instead of winding the wire winding (7) on a bobbin, sleeve or the like, the wire winding is attached directly to a surface of the winding sheet (1.3) by means of a self-bonding technique.
