Zusammenfassung:A high-voltage winding for core-form power transformers is disclosed that uses two different conductor configurations within a single coil to minimize eddy current losses. The winding 5 includes a first elongated conductor bundle 7 formed from a plurality of thin enamel coated conductor ribbons 8 arranged in side by side relation. A plurality of second elongated conductor bundles 40 are each formed from at least one bundle section 42 having a multiplicity of elongated insulated conductor strands 45 arranged in side by side relation. Each of the conductor strands 45 is less than 40 mils thick. The coil includes a top end section 22, a body section 20 and a bottom end section 24. The body section 20 is spirally wound with the first conductor bundle. The top and bottom end sections are wound with the second conductor bundles. In windings that include tap connectors, the tap section 26 is also wound with one of the second conductor bundles 40.
