Abstract
A winding for a transformer or choke coil wherein successive turns are arranged onto each other in radial direction. To provide for optimal cooling conditions axially extending cooling channels are provided by placing spacers between the successive radial turns of the winding. To provide for a limited volume, the turns which are adjacent to each other in the axial direction are located directly onto each other without interspacing.
