  Isolierhülle für elektrische Leiter, in weichen grosse Temperatur-Erhöhungen stattfinden, wie Wicklungen von Dynamomaschinen, Motoren, Transformatoren, Widerstände   u.   dgl. 



   Die   übliche Umkleidung elektr. I. eiter   mit   Baumwolle   bei Dynamomaschinen, Transformatoren, Widerständen und dgl. zeitig,t speziell bei höheren Spannungen, einen all-   mählichen   Zerfall dieses Isolationsmittels, welches dann ein Durchschlagen der Spulen, Windungen etc. zur Folge hat. 



   Die bekannte Ursache dieser Erscheinung besteht in der Bildung von Salpetersäure, hervorgerufen durch elektrische Entladungen (Überspannungen), wodurch, infolge der im elektrischen Leiter auftretenden Wärme begünstigt, der Zerfall der Baumwollfaser eintritt. 



   Dieser Zerfall der   Baumwoll-   (vegetabilischen) Faser kann als   Karbonisationsprozess

   Dagegen ist die Schafwolle den erwähnten Veränderungen nicht unterworfen, d.   h.   sie unterliegt nicht ein-er   Verkohlung bei Einwirkung von   Säure und   Wärme, wie   dieses durch Versuche und   Erfahrungen   festgestellt wurde. Durch Anwendung von Schafwolle als Isolationsmittel wird   daher   ein Durchschlagen, bzw. Zerstören der Isolationsschicht wirksemer vermieden.

  Insulating sheath for electrical conductors, in which large temperature increases take place, such as windings of dynamo machines, motors, transformers, resistors and the like. like



   The usual casing electr. I. eiter with cotton in dynamo machines, transformers, resistors and the like. Early, t especially with higher voltages, a gradual disintegration of this insulating medium, which then has a breakdown of the coils, windings etc. result.



   The well-known cause of this phenomenon is the formation of nitric acid, caused by electrical discharges (overvoltages), which, as a result of the heat generated in the electrical conductor, causes the cotton fibers to break down.



   This decay of the cotton (vegetable) fiber can be called the carbonization process

   In contrast, the sheep's wool is not subject to the changes mentioned, i. H. it is not subject to charring when exposed to acid and heat, as has been established through experiments and experience. By using sheep's wool as an insulation means, penetration or destruction of the insulation layer is avoided more effectively.
