The secondary winding of a high power transformer for clocked power supplies is composed of a plurality of skeins extending parallel to one another which are, in turn, constructed of a plurality of stranded conductors extending parallel to one another, whereby the stranded conductors are composed of wire-shaped individual conductors respectively provided with an insulating surface and twisted or woven with one another. All stranded conductors are electrically and mechanically connected to one another at both ends of their respective skeins and all skeins are connected to one another at one end of the secondary winding and connected to one another across respective rectifiers at the other end thereof.
