Description

Als Zuleitung für Pupinspulenkästen o. dgl. dienende Gummiader Die Isolation der Zuleitungen in Pupinspulenkästen verringert sich bekanntlich im Laufe der Zeit häufig ganz beträchtlich. Dies hat seinen Grund darin, daß die als Zuleitungen verwendeten Gummiadern durch die in den Vergußmassen enthaltenen öl-, wachs-oder harzartigen Stoffe angegriffen werden. Für andere Zwecke sind nun Gummiadern bereits bekannt geworden, die mit einer Schutzlackierung direkt auf dem Gummi oder auf einer darübergezogenen - Textilbandage versehen. sind. Derartige Gumnv:adern sind jedoch ebenfalls nicht genügend imprägnierbeständig, da einmal die Lösungsmittel des Lackes den Gummi bereits angreifen und anderseits keine so vollständig geschlossene Lackschicht zustande kommt, die eine Einwirkung völlig ausschließt.As a supply line for Pupin spool boxes or the like. Serving rubber core Die As is well known, insulation of the supply lines in pupin coil boxes is reduced in the course of the process the time is often quite considerable. The reason for this is that the as feed lines rubber veins used by the oil, wax or contained in the casting compounds Resin-like substances are attacked. Rubber veins are now already used for other purposes became known that with a protective coating directly on the rubber or on a textile bandage pulled over it. are. Such Gumnv: veins are, however also not sufficiently resistant to impregnation, as there are solvents in the paint already attack the rubber and, on the other hand, not such a completely closed layer of lacquer comes about, which completely excludes any influence.

Um nun Zuleitungen. für Pupinspulenkästen zu bekommen, die allen Anforderungen hinsichtlich Imprägnierbeständigkeit genügen, wird gemäß der Erfindung der Gummidraht mit einem völlig dichten, undurchlässigen Stoff, wie- beispielsweise Ölseide, ölleinen o. dgl., zweckmäßig mit überlappung fest bandagiert und über dieser Bandage eine geschlossene Lackschicht, beispielsweise aus Ölsack, angebracht. Diese Lackschicht hat den Zweck, auch ein allmähliches Eindringen der Massen durch die Spalten bei längeren Imprägnierungen zu verhindern. Eine auf diese Weise imprägnierbeständig gemachte 5 in lange Gummiader in D.. M. Viererverseilung zeigte nach 3ostündiger Imprägnierdauer in einer Kolophonium-Vaseline-Mischung einen Isolationswiderstand von 500000 iMegehm, während der Isolationswiderstand einer 5 m langen Doppelader mit derselben Gummiisolation, jedoch mit Baumwollbeflechtung und Lacküberzug, bereits auf den fünfzigsten Teil gesunken war.To now supply lines. For Pupin spool boxes that meet all requirements with regard to impregnation resistance, according to the invention, the rubber wire is firmly bandaged with a completely dense, impermeable material such as oil silk, oil linen or the like, expediently with an overlap and a closed layer of varnish over this bandage, for example from an oil sack attached. The purpose of this lacquer layer is to prevent gradual penetration of the mass through the gaps during longer impregnations. A 5 in long rubber core made in this way impregnation-resistant in D .. M. Quadruple stranding showed an insulation resistance of 500,000 iMegehm after 3 hours of impregnation in a rosin-vaseline mixture, while the insulation resistance of a 5 m long twin core with the same rubber insulation, but with cotton braiding and Lacquer coating, had already sunk to the fiftieth part.

Die Anwendbarkeit von Gummileitungen, die gemäß der Erfindung imprägnierbeständig gemacht sind, beschränkt sich im übrigen nicht auf Pupinspulenkästen, sondern ist stets dann gegeben, wenn Leitungen irgendwelcher Art dem Angriff von öl-, wachs- oder harzartigen Vergußrnassen ausgesetzt sind.The applicability of rubber cables, which according to the invention are resistant to impregnation are made, is not limited to Pupin coil boxes, but is always given when pipes of any kind are susceptible to attack by oil, wax or are exposed to resinous potting compounds.
