Description

Verfahren zur Isolierung der Teilleiter von ganz oder annähernd rechteckförmigen Gesamtleitern, die durch Verseilen von rechteckförmigen, voneinander durch oxydiertes lnetallband, insbesondere Aluminiumband, isolierten Teilleitern hergestellt werden Es ist bekannt, Teilleiter von rechteckigem Querschnitt, die zu einem Gesamtleiter von ganz oder annähernd rechteckigem Querschnitt zusammengefügt werden, durch ein zwischengelegtes oxydiertes Aluminiumband voneinander zu isolieren. Die Anbringung dieser Isolierung bietet aber Schwierigkeiten bei Leitern, die durch Verseden hergestellt werden, wie es von der Herstellung von Seilen bekannt ist, und hinterher unter Umständen noch zusammengepreßt werden. Beim Verseilen wird das Isolierband, insbesondere wenn die hierbei entstehende Form einen vom runden abweichenden Querschnitt besitzt, der sich einem Rechteck mit kurzen und langen Seiten nähert, über seine schmale Kante verbogen werden müssen, was praktisch schwer oder gar nicht ausführbar ist. Gerade bei den verseilten und zusammengepreßten Leitern ist aber die Verwendung von metallischem Isolierband von außerordentlich großer Bedeutung, da Faserstoffisolation nicht nur beim Verseilen ebenfalls schwierig einzuführen ist, sondern beim Zusammenpressen auch stets zerstört wird.Method for isolating the sub-conductors from completely or approximately rectangular Overall conductors, which are made by stranding rectangular, each other by oxidized Metal tape, in particular aluminum tape, insulated sub-conductors are produced It is known, sub-conductors of rectangular cross-section, which form an overall conductor be joined together by a completely or approximately rectangular cross-section to isolate the interposed oxidized aluminum tape from each other. The attachment however, this insulation presents difficulties with ladders that are made by sanding as it is known from the manufacture of ropes, and afterwards possibly still to be compressed. When stranding the insulating tape, especially if the resulting shape has a cross-section that differs from the round one, which approaches a rectangle with short and long sides over its narrow one Edge must be bent, which is difficult or impossible to implement in practice. But it is precisely the use of stranded and compressed ladders of metallic insulating tape is extremely important, as fiber insulation difficult to insert not only when stranding, but also when compressing is also always destroyed.

Man kann nun oxydiertes Aluminium auch in den genannten Fällen verwenden, wenn man nach der Erfindung nicht fortlaufendes Band anwendet, sondern das Band in einzelnen Stükken zwischen die voneinander zu isolierenden Leiter einfügt. Die Stücke werden vorteilhaft so groß gewählt, daß an jeder breiten Seite des Gesamtleiters zwischen je zwei Windungen zweier Teilleiter je ein Stück oxydiertes Band liegt, An Stelle des oxydierten Aluminiums kann auch irgendein anderes oxydiertes Metall verwendet werden, dessen Oxydschicht der erforderlichen Isolationsfähigkeit, genügt.Oxidized aluminum can now also be used in the cases mentioned, if you do not use continuous tape according to the invention, but the tape inserts in individual pieces between the conductors to be insulated from one another. the Pieces are advantageously chosen so large that on each broad side of the overall conductor between every two turns of two sub-conductors there is a piece of oxidized tape, Instead of the oxidized aluminum, any other oxidized metal can also be used be used, the oxide layer of which is sufficient for the required insulation.

Die Erfindung ist in der Zeichnung durch ein Ausführungsbeispiel veranschaulicht. Mit z, 2, 3 und 4 sind Leiter bezeichnet, die durch Verseilen um eine Achse nebeneinandergewunden sind, wobei zunächst ein Gesamtleiter von rundem oder annähernd eckigem Querschnitt gebildet wurde, der außerdem noch zusammengepreßt worden ist, so daß ein Stab mit zwei breiten und zwei schmalen Seiten entstand. Nach der Erfindung besteht nun die Isolation zwischen je zwei Leitern nicht aus einem einzigen fortlaufenden mitverseilten oxydierten Metallband, sondern aus einzelnen zwischengelegten Stücken derartigen Bandes. So sind in dem angeführten Beispiel auf der Vorderseite des Stabes einzelne Stücke =2, 23 und 34 zwischen die Windungen der Teilleiter x, 2, 3 und 4 gelegt, auf der ebenfalls flachen Rückseite die Stücke i2', 23' und 34. An den Schmalseiten sind keine besonderen Stücke eingefügt. Die dargestellte Anordnung ergibt eine besonders einfache Isolierung zwischen den Leitern, da sie die Anzahl der Stücke auf ein Mindestmaß beschränkt.The invention is illustrated in the drawing by means of an exemplary embodiment. Z, 2, 3 and 4 denote conductors which are wound next to one another by stranding around an axis are, initially an overall conductor of round or approximately angular cross-section was formed, which has also been pressed together so that a rod with two broad and two narrow sides emerged. According to the invention, there is now the Isolation between any two conductors does not consist of a single continuous stranded conductor oxidized metal tape, but from individual interposed pieces of this kind Band. In the example given, there are individual ones on the front of the rod Pieces = 2, 23 and 34 placed between the turns of sub-conductors x, 2, 3 and 4, on the also flat back the pieces i2 ', 23' and 34. On the narrow sides no special pieces are inserted. The arrangement shown gives a special one easy insulation between conductors as it keeps the number of pieces to a minimum limited.
