Abstract:
A winding of enameled wire comprising:a plurality of contiguous turns formed from an enameled wire, wherein said plurality of contiguous turns are in pressure contact with each other at contacting areas, and are bonded to each other, whereinsaid enameled wire has a high resistance to partial discharges and includes a smooth surface, said enameled wire further includes an electrical conductor and at least two layers of enamel on said conductor wherein the outermost layer of said layers constitutes an overcoat and is made from thermo-adherent resin defining said smooth surface of said wire, and a directly underlying layer made from a resin charged with weakly conductive particles;the weakly conductive particles of the directly underlying layer are in contact at said contacting areas between the turns to ensure a homogenous distribution of an electrical field across all the turns, andthe outermost layer fills gaps between the turns, bonds the turns to each other and provides an external protection for the winding.
