Description

Es ist bekannt, bei einem-elektrischen Leiter für isolierte Hochspannungskabel blanke Kupferdrähte eng aneinander in den Hohlraum zwischen zwei Rohre aus Weichmetall zu legen. Dadurch soll der Halbmesser des Leiters vergrößert werden, ohne den Kupferquerschnitt über das zur Stromleitung erforderliche Maß zu vergrößern; das äußere Rohr hat dabei die Aufgabe, die kreisrunde Gestalt des Leiters auch bei Biegungen zu sichern und eine glatte Oberfläche zu gewährleisten.It is known in an electrical conductor for insulated high voltage cables bare copper wires close together in the cavity between two tubes made of soft metal to lay. This is intended to increase the diameter of the conductor without the copper cross-section to enlarge beyond what is necessary to conduct electricity; the outer tube has it the task of securing the circular shape of the conductor even with bends and to ensure a smooth surface.

Demgegenüber bezieht sich die Erfindung auf einen selbsttragenden elektrischen Hohlleiter für Hochspannungsfreileitungen. Ein solcher Hohlleiter besteht gemäß der Erfindung aus einem zwischen zwei nahtlosen Metall-, insbesondere Aluminiumrohren eingebetteten, in an sich bekannter Weise aus einzelnen Verseilelementen, insbesondere aus Stahl oder Stahl-Aluminium-Drähten, aufgebauten Hohlseil, Hier dienen also gegenüber dem vorerwähnten Leiter für Hochspannungskabel die nahtlosen Rohre zur Stromleitung, während die dazwischenliegenden Drähte vor allem die Zugfestigkeit des Leiters gewährleisten sollen.In contrast, the invention relates to a self-supporting electrical waveguide for high voltage overhead lines. Such a waveguide exists according to the invention from one between two seamless metal, in particular aluminum tubes embedded, in a manner known per se from individual stranding elements, in particular made of steel or steel-aluminum wires, constructed hollow rope, so here serve opposite the above-mentioned conductor for high-voltage cables the seamless pipes for the power line, while the wires in between ensure above all the tensile strength of the conductor should.

In der Zeichnung ist ein Ausführungsbeispiel eines Hohlleiters gemäß der Erfindung dargestellt. Dieser Hohlleiter besteht aus einer Verseillage von Stahldrähten 4, die über einem inneren nahtlosen Rohr 5 angeordnet ist und außen durch ein weiteres nahtloses Rohr 6 umschlossen wird. Die Rohre 5 und 6 können aus Rein- oder Reinstaluminium bestehen und werden zweckmäßig durch ein an sich bekanntes Verfahren, z. B. durch Ziehen, fest an die Drähte 4 zur Anlage gebracht, wobei die Zwischenräume zwischen diesen teilweise ausgefüllt werden. Durch diesen Ziehprozeß wird zugleich eine Verfestigung der Aluminiumrohre erzielt.In the drawing, an embodiment of a waveguide is shown in FIG of the invention shown. This waveguide consists of a stranded layer of steel wires 4, which is arranged over an inner seamless tube 5 and on the outside by another seamless tube 6 is enclosed. The tubes 5 and 6 can be made of pure or pure aluminum exist and are expediently carried out by a method known per se, e.g. B. by Pull firmly on the wires 4 butted, leaving the spaces between these have to be partially filled out. This drawing process also results in a solidification the aluminum tubes achieved.

Bei der Herstellung von Hohlleitern gemäß der Erfindung kann es von Vorteil sein, zur Herabsetzung der Reibung zwischen den das Hohlseil bildenden Drähten, diese vor dem Aufpressen des Mantels einzufetten.In the manufacture of waveguides according to the invention, it can be from Be an advantage to reduce the friction between the wires forming the hollow rope, grease them before pressing on the jacket.
