    Verbundleiter i'iir elektrische Freileitungen.   



   Verbundleiter für elektrische Freileitungen 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   ipi   Kern nicht entstehen. 



   Wir haben   jedoch gefunden, dass auch in diesen)   Falle Energieverluste durch Hysterese und Wirbel-

   Nach der Erfindung soll, um diese Verluste 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

   Schliesslich können nach der Erfindung die Verluste dadurch herabgesetzt werden, dass man Metalle mit geringeren   Hystereseverlusten,   geringerer elektrischer Leitfähigkeit oder solche, denen diese beiden Eigenschaften gemeinsam anhaften, auswählt, beispielsweise Eisensiliziumlegierungen. 



   PATENT-ANSPRÜCHE :
1. Verbundleiter für elektrische Freileitungen. dadurch gekennzeichnet, dass der im Innern des Leiters angeordnete   Tragkörper aus nicht   oder mir sehr schwach   magnetisierbarem   Metall besteht, das hohe   Drllck- und Zugfestigheit   hat.

    Composite conductors for electrical overhead lines.



   Composite conductors for electrical overhead lines usually consist of lead 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 fluxes of force ipi core do not arise.



   However, we have found that in this case too, energy losses due to hysteresis and vortex
 EMI1.1
 



   According to the invention, in order to reduce or avoid these losses, 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 one that is not or only extremely weakly magnetizable
 EMI1.2
 isolate each other.



   Finally, according to the invention, the losses can be reduced by selecting metals with lower hysteresis losses, lower electrical conductivity or those that have these two properties together, for example iron-silicon alloys.



   PATENT CLAIMS:
1. Composite conductor for electrical overhead lines. characterized in that the support body arranged in the interior of the conductor consists of metal which is not magnetizable or is very weakly magnetizable and has high pressure and tensile strength.
