Description

Elektrische Isolation Die auf elektrotechnischem. Gehbiet verwendeten Isolierstoffe haben bekanntlieb mannigfachen Bedinigungen zu genügen. Vor allem wird bei. ihnen die Forderung nach hoher Sp.annungs- und gewisser Temperaturfestigkeit erhoben. Es kommen aber auch Fälle vor, wo die Isolation, nur geringen Spannungen, dafür aber verhältnismäßig recht hohen Temperaturen ausgesetzt werden, wie dies beispielsweise bei Regelwiderständen u. dgl. der Fall ist, bei denen der Regelkontakt vielfach unmittelbar auf der blankgemachten Regelwicklung schleift. Die vorgenannten Bedingungen hinsichtlich geringer Spannungs-, aber hoher Temperaturbeanspruchung erfüllt eine Isolierschicht für elektrische Leiter u. dgl., die gemäß der Erfindung aus Braunstein, insbesondere kristallisiertem Braunstein, besteht.Electrical Isolation Die on electrotechnical. Area used It is known that insulating materials have to satisfy a wide variety of conditions. Above all is at. them the requirement for high voltage and a certain temperature resistance raised. But there are also cases where the insulation, only low voltages, but are exposed to relatively high temperatures, like this This is the case, for example, with variable resistors and the like, in which the control contact often grinds directly on the bare standard winding. The aforementioned Conditions with regard to low voltage but high temperature stress meets an insulating layer for electrical conductors and the like made according to the invention consists of brownstone, in particular crystallized brownstone.

Die erfindungsgemäße Isolierschicht kann als dünner Überzug, der vorzugsweise kleiner als i ,u stark ist, nach irgendeinem bekannten Verfahren auf den zu isolierenden Gegenständen aufgebracht werden. Vorteiffiaft ist, daß der erfindungsgemäße Isolierstoff trotz sehr hoher thermischer Beanspruchung im Gegensatz zu den bisher gebräuchlichen organischen Isolierstoffen, z. B. Lacken, nicht brennt und daß er sich vor allem, in äußerst dünner Schicht wirkungsvoll anbringen läßt.The insulating layer according to the invention can be used as a thin coating, preferably less than i, u is strong, by any known method on the to be isolated Objects are applied. The advantage is that the insulating material according to the invention despite very high thermal stress in contrast to the previously common ones organic insulating materials, e.g. B. varnish, does not burn and that above all, can be applied effectively in an extremely thin layer.
