Abstract
A regulating winding for a high power transformer which includes a conductor bunch having a multiplicity of series-connected, parallel conductor loops, each loop comprising at least two parallel loop strands. The conductor bunch includes a number of radial and/or axial cooling channels, and the loop strands and the cooling channels are so arranged that the voltage difference between two loop strands located adjacent each other, and preferably positioned together between two cooling channels, is considerably higher than the voltage difference between loop strands positioned on either side of the cooling channels.
