FOIL WINDING LEADS AND METHOD FOR FORMING THE SAME

Abstract: an insulated winding assembly comprising an insulated foil conductor comprising a lead-in section, a lead-out section and a winding section between the lead-in and lead-out sections, wherein in the winding section, the insulated foil conductor is wound around a core material to form windings, wherein each of the lead-in and lead-out section is folded with respect to the winding section and arranged transverse to the windings of the winding section, and wherein each of the lead-in and lead-out section comprises at least one folding cut along a lengthwise direction of the foil conductor, thereby forming at least two strips. a corresponding method and a transformer comprising such a winding assembly is also presented herein.
