ABSTRACT:
An electrical winding for electrical inductive apparatus such as a transformer or electrical reactor having at least one winding formed of non-magnetic, electrically conductive sheet, strip or foil, such as copper or aluminum. Magnetically conductive material is disposed between at least certain of the turns of the electrically conductive sheet material to create a low reluctance path for magnetic leakage flux parallel to the winding axis to reduce the magnitude of the radial component of the leakage flux.
