Description

Für .die Verbindung· elektrischer Leiter haben sich1 die Aridschien Rohre am besten bewährt. Die Leiter werden von den entgegengesetzten Enden her in ein Rohr ovalen Quer-Schnitts eingeführt und miteinander verdrillt, wie bei α in Fig. ι gezeigt ist. Bei Verbundleiterseilen, die z. B. aus einer inneren Stahllitze b und einer äußeren Doppellage c aus Alumiumdrähten bestehen, hat sich jedochFor .the connection · electrical conductor 1, the Aridschien pipes have proven best. The conductors are introduced from the opposite ends into a tube of oval cross-section and twisted together, as shown at α in FIG. In composite conductor ropes, which z. B. consist of an inner steel strand b and an outer double layer c made of aluminum wires, but has

ίο gezeigt, daß sich bei stärkerem Zuge zunächst die Stahlkerne herausziehen, dia sie den stärksten Zug aufzuhalten haben, aber verhältnismäßig wenig Reibung finden. Bei starkem Frostwetter ziehen sich die Aluminiumdrähte stark zusammen und können dann ebenfalls aus der Verbindung herausgezogen werden.ίο shown that with stronger train initially pull out the steel cores as they have to stop the strongest pull, but proportionately find little friction. In severe frosty weather, the aluminum wires pull together strongly and can then can also be pulled out of the connection.

Um dies zu vermeiden, wird nach der Erfindung das Rohr α an beiden Enden mit Köpfen d versehen, die von innen nach außen kegelförmig· ausgebohrt sind, wie bei e (Fig. 2) gezeigt ist. In jeden Kopf wird das vom andern Ende kommende Verbundseil Cc1 eingeführt, und' zwar so, daß hauptsächlich die Stahllitze b in den Ansatz hineinragt. Die Stahldrähte b werden ausgespreizt, umgebogen und mit einer Metallegierung vergossen. Bei etwaigem Zuge kann sich der Stahlkern nun nicht mehr aus der Kupplung herausziehen. Von den- Aluminiumdirähten c wird meistens nur die innere Lage bis in die kegelförmige Ausbohrung des Kopfes d geführt, wodurch auch die _ StaWlseele gegen Eindringen von Feuchtigkeit gesichert wird.In order to avoid this, according to the invention, the tube α is provided at both ends with heads d which are drilled in a conical shape from the inside to the outside, as shown at e (FIG. 2). The composite cable Cc 1 coming from the other end is inserted into each head, in such a way that mainly the steel strand b protrudes into the approach. The steel wires b are spread out, bent and cast with a metal alloy. In the event of a pull, the steel core can no longer pull itself out of the coupling. Of the aluminum wires c , mostly only the inner layer is led into the conical bore of the head d, whereby the steel core is also secured against the ingress of moisture.

Atif die gleiche Weise können) die Verbundseile in Endbunden gesichert werden.Atif the same way you can) the composite ropes be saved in final bundles.
