  Verbundleiter für elektrische   Freileitungen.   



   Verbundleiter für   elekt1Ísrhe Fleileitungen   bestehen in der Regel aus Leitungsdrähten, die um einen Tragkern aus Eisen-oder Stahldrähten in Form eines Seiles oder einer Drahtschraube oder beider verseilt sind. 



   Man hat bisher angenommen, dass bei dieser Anordnung des Eisens im Innern des Leiters schädliche, d. h. Verluste verursachende magnetische   Kraftflüsse   im Kern nicht entstehen. 



   Wir haben jedoch gefunden, dass auch in diesem Falle Energieverluste durch Hysterese und Wirbelströme auftreten. 



   Nach dem Stammpatent Nr. 109013 soll, um diese zu verringern oder zu vermeiden, für den Tragkörper ein Metall benutzt werden, das neben hoher Druck-und Zugfestigkeit die Eigenschaft hat, dass es nicht magnetisierbar ist, wie beispielsweise Bronze oder eine nicht oder nur äusserst schwach magnetisierbare Eisenlegierung. Es können aber Fälle eintreten, dass man mit   Rücksicht   auf die Preisfrage oder auf höhere Zugfestigkeit doch Drähte aus magnetisierbarem Metalle verwenden will oder muss. Um nun auch bei diesen die Verluste durch Hysterese oder Wirbelströme zu vermeiden oder herabzusetzen, sollen nach vorliegender Erfindung die den inneren Tragkörper bildenden Drähte aus magnetisieibarem Metalle hergestellt, aber unterteilt oder gegeneinander isoliert werden.

  Composite conductors for electrical overhead lines.



   Composite conductors for electrical cables usually consist of conductor wires that are stranded around a support core made of iron or steel wires in the form of a rope or a wire screw or both.



   It has hitherto been assumed that with this arrangement of the iron inside the conductor, harmful, i.e. H. Loss-causing magnetic force flows in the core do not arise.



   However, we have found that in this case too, energy losses occur due to hysteresis and eddy currents.



   According to the parent patent no. 109013, in order to reduce or avoid this, a metal should be used for the support body which, in addition to high compressive and tensile strength, has the property that it is not magnetizable, such as bronze or not or only extremely weakly magnetizable iron alloy. However, there may be cases where, in view of the question of price or higher tensile strength, you want or have to use wires made of magnetizable metals. In order to avoid or reduce the losses due to hysteresis or eddy currents in these as well, according to the present invention the wires forming the inner support body should be made of magnetizable metals, but divided or insulated from one another.
