Description

Kabelmäntel aus Aluminium Es ist bekannt, Kabelmäntel aus Aluminium herzustellen, wozu neuerdings Reinstaluminium benutzt wird, das im allgemeinen auf dem Wege der Schmelzflußelektrolyse hergestellt ist.Cable sheaths made of aluminum It is known, cable sheaths made of aluminum to produce, for which purest aluminum has recently been used, which is generally based on is made by the way of fused-salt electrolysis.

Die hierbei anfallenden Gußblöcke müssen in die gewünschte Form auf dem Schmelzwege übergeführt werden. Dieses Verfahren hat den großen Nachteil, daß bei diesem Umschmelzen leicht Verunreinigungen in das Aluminium eingebracht werden, die die Korrosionseigenschaften stark beeinträchtigen und somit das Material .oftmals vorzeitig unbrauchbar machen.The resulting cast blocks must be in the desired shape be transferred to the melting path. This method has the major disadvantage that During this remelting process, impurities are easily introduced into the aluminum, which severely impair the corrosion properties and thus the material make it unusable prematurely.

Erfindungsgemäß wird dieser Nachteil durch den Vorschlag vermieden, für die Herstellung von Kabelmäntelsi solches Reinstaluminium zu verwenden, das auf dem Sinterwege aus Reinstaluminiumpulver erhalten wird, wobei dieses Pulver vorzugsweise auf dem Wege der wäßrigen Elektrolyse hergestellt wird. Es hat sich gezeigt, daß Kabelmäntel, die aus einem auf diese Weise gewonnenen R@einstaluminium bestehen, eine wesentlich bessere Korrosionsfestigkeit als die bisherigen Aluminiumkalyelmäntel besitzen, was sich darauf zurückführen läßt, daß dem Metall während des Her-, stellungs- und Verarbeitungsprozesses keime Gelegenheit gegeben wird, irgendwelche Verunreinigungen aufzunehmen.According to the invention, this disadvantage is avoided by the suggestion, to use such pure aluminum for the production of cable sheaths that is obtained by sintering from pure aluminum powder, this powder is preferably produced by means of aqueous electrolysis. It has showed that cable sheaths made from a R @ erstaluminium exist, a much better corrosion resistance than the previous aluminum kalyel coats which can be traced back to the fact that the metal and processing germs an opportunity is given to any impurities to record.
