Description

Die bisher zur Abspannung von \Freileitungs-, insbesondere Stahl-Aluminiumseilen bei Hängeisolatoren bekannten Anordnungen sind, da sie davon ausgehen, die Stahlseele mit dem Aluminiummantel gesondert abzuspannen, kompliziert, teuer in der Herstellung und schwierig zu montieren. Vielfach werden für dieselben auch Metalle mit hohem Potentialabstand verwendet, und zwar insbesondereThe previously used to tension \ overhead line, in particular steel-aluminum ropes are known arrangements for suspension insulators, as they assume that the steel core with the aluminum jacket will be braced separately, complicated, expensive to manufacture and difficult to assemble. Be multiple metals with high potential spacing are also used for the same, in particular

ίο für die sogenannten Konusabspannungen, wodurch die vorzeitige Zerstörung der gerade beanspruchten, Stellen begünstigt wird.ίο for the so-called cone bracing, whereby the premature destruction of the areas currently being used is favored.

Wenn andererseits die Stahlseele und der Aluminiummantel gleichzeitig gefaßt werden, verwendet man gewöhnlich Reinaluminium. Das aber erfordert große Längen und Querschnitte der die Abspannung vermittelnden Teile.On the other hand, if the steel core and the aluminum jacket are grasped at the same time, usually pure aluminum is used. But that requires great lengths and cross-sections of the parts providing the bracing.

Ein weiterer Nachteil der bekannten Einrichtungen dieser Art ist darin zu erblicken, daß der Verschiedenheit der mechanischen Eigenschaften der zur Abspannung herangezogenen Baustoffe nicht genügend Rechnung getragen wird.Another disadvantage of the known devices of this type is to be seen in the fact that that the difference in the mechanical properties of those used for bracing Building materials are not sufficiently taken into account.

Die Erfindung ist bestimmt, diese Nachteile zu beseitigen. Zu diesem Zwecke werden zwei oder mehrere Stoßverbinder verwendet, deren Teile gelenkig oder schwingbar miteinander verbunden sind und die aus vergütbaren Aluminiumlegierungen bestehen, deren Festigkeitseigenschaften ungefähr den Gesamtfestigkeiten der Stahlseele und des Aluminiummantels entsprechen.The invention is intended to obviate these drawbacks. Be for this purpose two or more butt connectors are used, the parts of which are articulated or swingable with one another are connected and which consist of heat treatable aluminum alloys, their strength properties correspond approximately to the total strength of the steel core and the aluminum jacket.

Die Gefahr, die aus dem Potentialabstand der bei bekannten Abspannungsvorrichtungen verwendeten verschiedenen Baustoffe sich er-The danger arising from the potential distance of the known tensioning devices used different building materials

gibt, wird beseitigt, da der Potentialabstand zwischen dem Aluminiummantel und dem aus vergiitbaren Aluminiumlegierungen bestehenden Verbinder praktisch nicht in Erscheinung tritt.there is eliminated as the potential gap between the aluminum jacket and the out Available connectors in aluminum alloys are practically non-existent occurs.

Die Verbinder sind an den Enden, wo das Seil nicht angeschlossen ist, ösenartig ausgebildet und werden durch einen Bolzen, der durch die Ösen hindurchtritt, zusammengehalten. Zur Lagerung des Bolzens ist ein Gabelkopf vorgesehen, an welchem die Isolatorkette angeschlossen ist.The connectors are eyelet-like at the ends where the rope is not connected and are held together by a bolt that passes through the eyelets. To support the bolt, a fork head is provided on which the isolator chain connected.

Die neue Abspannvorrichtung ist in den Abbildungen beispielsweise dargestellt, und zwar zeigt:The new guying device is shown in the figures, for example, and although shows:

Die Abspannvorrichtung besteht im vorliegenden Ausführungsfalle aus den beiden Stoßverbindern av a2, für die hier der sogenannte Hedde,rnheimer Verbinder gewählt ist.In the present embodiment, the tensioning device consists of the two butt connectors a v a 2 , for which the so-called Hedde, Rnheimer connector is selected here.

Die Enden der beiden TeileU1, az, welche nicht an das Seil S angeschlossen sind, sind zu Ösen O1 und b2 ausgebildet Zu ihrer Verbindung dient der Bolzen <2, welcher durch Bohrungen C der Ösen hindurchtritt.The ends of the two parts U 1 , a z , which are not connected to the rope S, are formed into eyelets O 1 and b 2. The bolt <2, which passes through holes C of the eyelets, serves to connect them.

Der Bolzen und gleichzeitig die Ösen sind in dem Gabelkopf e gelagert, welcher mit einem Bügel/ zum Anschluß an die Isolatorkette k ausgebildet ist.The bolt and at the same time the eyelets are mounted in the fork head e , which is designed with a bracket / for connection to the insulator chain k .
