Abstract

Die vorliegende Erfindung betrifft einen Leiter für flüssigkeitsgekühlte Wicklungen, insbesondere für Transformatorwicklungen mit einer den Leiter (1) als ganzen umgebenden isolierenden Ummantelung, wobei zumindest eine Lage (2) der Ummantelung den Leiter (1) vollständig abdeckend umgibt, während eine äussere Lage (3) von mindestens zwei Lagen (2, 3) der Ummantelung Öffnungen (4), Maschen (5) oder Ausfransungen (6) aufweist, wodurch eine den Leiter umströmende Kühlflüssigkeit in Turbulenzen versetzt und ein besserer Wärmeaustausch erreicht wird. Die Erfindung betrifft ferner einen entsprechenden flüssigkeitsgekühlten Transformator und eine flüssigkeitsgekühlte Drosselspule.
