 EMI1.1 
 



   Es hat sich gezeigt, dass die Isolation elektrischer Luftkabel von geringer Steifigkeit, bei Befestigung der Kabel an festen Punkten, nach kurzer Zeit an den Befestigungsstellen zerstört wird. Die Ursache   hiefür liegt   darin, dass solche Kabel wegen ihrer geringen Steifigkeit schon bei tnässigem Winde beträchtliche Schwingungen ausführen, so dass die Isolation sich fast dauernd an den Befestigungsstellen reibt. Dieselbe Erscheinung tritt bei Aufhängung solcher Kabel an Tragdrähten ein. Die Isolation wird hierbei nicht nur an den Einführungsstellen des Kabels in die an Masten befestigten   Kabelmunen,   sondern auch an den vielen Aufhängepunkten zerstört. 



  Auch eine Armierung des Kabels verhindert nicht, dass die Isolation besonders in der Nähe der Kabelmuffen brüchig wird. 



   Durch die Erfindung sollen die angeführten Übelstände beseitigt werden ; wertvoll ist ausserdem, dass die Verwendung eines teuren   Tragdrahtcs   vermieden und wenn das Kabel einigermassen steif ist und genügende   Fertigkeit   besitzt, sogar eine Armierung entbehrlich ist. 



   Die Erfindung besteht darin, dass nicht nur die Längsverspannungen in der bei Fahrdrähten bekannten Weise an Auslegern frei schwingend aufgehängt, sondern auch die Verbindungsstücke   (Verbindungsrnuffen, Abzweigmuffen) durch   Pendel unmittelbar an Auslegern derart beweglich 
 EMI1.2 
 dabei das Kabel nicht durch das Gewicht der Verbindungsstücke belastet wird. 



   In der Figur ist eine Ausführungsform der Erfindung dargestellt. Das Kabel a ist durch Pendel b an dem Ausleger c schwingend aufgehängt und verspannt ; d ist eine Kabelmuffe, die durch Pendel f an der Ausleger c befestigt ist.

 EMI1.1
 



   It has been shown that the insulation of electrical aerial cables of low rigidity, if the cables are attached to fixed points, is destroyed after a short time at the attachment points. The reason for this lies in the fact that such cables, due to their low rigidity, vibrate considerably even in wet winds, so that the insulation rubs against the fastening points almost constantly. The same phenomenon occurs when such cables are suspended from suspension wires. The insulation is destroyed not only at the points where the cable enters the cable muns attached to the masts, but also at the many suspension points.



  Armouring the cable does not prevent the insulation from becoming brittle, especially in the vicinity of the cable sleeves.



   The invention is intended to eliminate the abuses mentioned; It is also valuable that the use of an expensive suspension wire is avoided and, if the cable is reasonably stiff and has sufficient skill, armouring can even be dispensed with.



   The invention consists in that not only the longitudinal braces are suspended freely swinging on brackets in the manner known from contact wires, but also the connecting pieces (connecting sleeves, branch sleeves) can be moved in this way by pendulums directly on brackets
 EMI1.2
 the cable is not burdened by the weight of the connectors.



   In the figure, an embodiment of the invention is shown. The cable a is suspended swinging by pendulum b on the arm c and braced; d is a cable sleeve attached to bracket c by pendulum f.
