Description
Elektrisches Kabel mit Aluminiummantel Wegen des geringen spezifischen Gewichtes und der großen Festigkeit von Aluminium hat man schon mehrfach versucht, das für Metallmäntel von elektrischen Kabeln.praktisch ausschließlich verwendete Blei durch Aluminium zu ersetzen. Es ist auch schon der Vorschlag gemacht worden, den Mantel eines elektrischen Kabels ,aus Reinstaluminium herzustellen, das einen Reinheitsgrad von 99,9% und mehr aufweist. Reinstaluminium kommt in seinen plastischen Eigenschaften dem Blei sehr nahe und zeichnet sich überdies durch eine große Korrosionsbeständigkeit aus. Die praktische Auswertung des obigen Vorschlages stößt jedoch wegen des hohen Preises von Reinstaluminium auf Schwierigkeiten.Electric cable with aluminum sheath Because of the low specificity Weight and the great strength of aluminum, attempts have already been made several times that for metal sheaths of electrical cables. practically exclusively used Replace lead with aluminum. The suggestion has already been made the sheath of an electrical cable made of pure aluminum, one of them Has a degree of purity of 99.9% and more. Pure aluminum comes in its plastic Properties very close to lead and is also characterized by a high level of corrosion resistance the end. The practical evaluation of the above proposal, however, comes across because of the high The price of pure aluminum on difficulties.
Zur Reinigung von Metallen ist ein Verfahren `bekannt, das darin besteht, daß, das zu reinigende Metall unter vermindertem oder gegen verminderten Druck filtriert wird. Dies kann beispielsweise dadurch geschehen, daß mandie metallischen Werkstoffe in einem beliebigen Ofen schmilzt und sie dann durch ein im Boden des Ofens angeordnetes Filter durchsangt. Als Werkstoff für das Filter kann man "beispielsweise Graphit oder feinporige Kohle verwenden. Das Verfahren ermöglicht zwar nicht, die im Aluminium gelösten Beimengungen, wie z. B. Eisen und Silicium, in dem Maße wie beim Reinstaluminium zu entfernen, dagegen wird das Aluminium von olydischen Ventnreinigungen weitgehend befreit.A process for cleaning metals is known which consists in that the metal to be cleaned is filtered under reduced pressure or against reduced pressure will. This can be done, for example, by using the metallic materials melts in any furnace and then through one placed in the bottom of the furnace Filter through. The material for the filter can be, for example, graphite or use fine-pored charcoal. The process does not allow that in aluminum dissolved additions, such as. B. iron and silicon, to the same extent as with pure aluminum on the other hand, the aluminum is largely removed by olydic ventilations freed.
.. Ztvec% der Erfindung ist es; ein Kabel mit einem Aluminiummantel zu schaffen, der gute mechanische Eigenschaften aufweist und billig in der Herstellung ist. Die Erfindung besteht darin, daß zur Herstellung eines Kabelmantels aus Aluminium ein Aluminium benutzt wird, das ,auf bekannte Weise durch Filtration.unter vermindertem Druck oder gegen verminderten Druck gereinigt worden ist. Die Erfindung beruht auf der Erkenntnis, dar, oxydfreies. Aluminium auch dann, wenn es in geringen Mengen Beimengungen, wie z. B. Eisen und Silicium, einlegiert enthält, noch" in--eincm Maße plastisch ist, dafa ein daraus hergestellter Kabelmantel. eine ausreichende Biegsamkeit aufweist. Durch die Oxydfreiheit des Aluminiums werden seine plastische Verformbarkeit sowohl in der Kälte als auch in der Wärme und seine Fähigkeit, nach den beim Preßvorgang unvermeidlichen Trennungsvorgängen wieder vollständig zusammen7uschweißen, ganz wesentlich erhöht... Ztvec% of the invention is; a cable with an aluminum jacket to create, which has good mechanical properties and cheap to manufacture is. The invention consists in that for the production of a cable jacket made of aluminum an aluminum is used which, in a known manner, by filtration under diminished Pressure or has been cleaned against reduced pressure. The invention is based on of knowledge, is oxide-free. Aluminum even if it is in small quantities Additions, such as. B. contains iron and silicon, alloyed, still "in - eincm Dimensions are plastic because a cable sheath made from them. a sufficient one Has flexibility. Because aluminum is free from oxides, its plasticity becomes Deformability both in the cold and in the heat and its ability to recreate completely weld the separation processes that are unavoidable during the pressing process together again, increased significantly.
Die Herstellung des Kabelmantels gemäß der Erfindung erfolgt vorteilhaft auf übliche weise durch nahtlose Verpressung des . Aluminiums mit Hilfe des Strangpreßverfahrens, oder aber auch durch Verschweißung von achsenparallel oder schraubenlinienförmig auf die Kabelseele aufgelegten Bändern. Die Biegsamkeit des Kabelmantels kann durch 'nachträgliche Rillung noch verbessert «-erden.The cable jacket according to the invention is advantageously produced in the usual way by seamlessly pressing the. Aluminum using the extrusion process, or also by welding axially parallel or helically tapes placed on the cable core. The flexibility of the cable jacket can by 'Subsequent creasing even improved' - earth.
