  Isoliermaterial. 



   Bald nachdem die Darstellung der faserfreien, regenerierten Zellulose erfunden war, wurde ihre Brauchbarkeit auf die verschiedensten Gebiete hin untersucht. Jodoch hat sich herausgestellt, dass nur die Verwendung als neues Packmaterial Erfolg hatte. 



   Im Stammpatent Nr. 112237 ist die Erfindung beschrieben, dass regenerierte Zellulose, wie sie heute in den Handel kommt, in Kombination mit Dielektriken ein sehr gutes Isoliermaterial, auch für höhere Spannungen, ergibt, welches sogar die   Umspannung   mit Isolierseide bei weitem übertrifft. Bei der Ausarbeitung dieser Erfindung wurde die   überraschende   Beobachtung gemacht, dass die regenerierte Zellulose, die heute als   modernes Packmaterial   in Stärken von 0-008 mm aufwärts in den Handel kommt, schon für sich allein ohne Dielektrika ein   vorzügliches   Isoliermaterial darstellt, sobald es sich nicht um zu hohe Spannungen handelt wie z. B. in der Schwachstromtechnik.

   Nach diesen Feststellungen isoliert regenerierte Zellulose trotz des Glyzeringehaltes ohne Dielektrika bei 0'01 mm Stärke zirka 500 Volt, nähert sich also in ihrer elektrischen Widerstandsfähigkeit dem Isolierleinen. 



   Ausführungsbeispiel : 
 EMI1.1 
 



  Die Beanspruchungsdauer war dabei 2 Minuten und 14 Sekunden. 



   Die regenerierte Zellulose hat ferner als Isoliermaterial neben der Faserfreiheit auch den Vorteil der Durchsichtigkeit, wodurch nach Aufbringen der Isolation die isolierten Gegenstände noch gesehen werden können, was z. B. das Auffinden von   Defekten, wie Leitungsbrüchen, erleichtert.   Da die regene-   rie, rte   Zellulose als Packmaterial in allen Farben in den Handel kommt, so kann man die Leiter durch verschiedenfarbige Isolierung leichter unterscheiden oder z. B. aus geschmacklichen Gründen der Farbe der Umgebung gemäss wählen.

  Insulating material.



   Soon after the preparation of fiber-free, regenerated cellulose was invented, its usefulness in a variety of fields was investigated. Jodoch found that only the use as new packaging material was successful.



   In the parent patent no. 112237 the invention is described that regenerated cellulose, as it is on the market today, in combination with dielectrics, results in a very good insulating material, even for higher voltages, which by far exceeds even lashing with insulating silk. When working out this invention, the surprising observation was made that the regenerated cellulose, which is now commercially available as a modern packaging material in thicknesses from 0-008 mm and up, is an excellent insulating material in and of itself without dielectrics, as soon as it is not too high voltages, such as B. in low-voltage technology.

   According to these findings, despite the glycerine content, regenerated cellulose isolates about 500 volts at a thickness of 0.01 mm without dielectrics, and thus approximates the electrical resistance of the insulating line.



   Embodiment:
 EMI1.1
 



  The exposure time was 2 minutes and 14 seconds.



   The regenerated cellulose also has the advantage of transparency as an insulating material in addition to the absence of fibers, which means that the isolated objects can still be seen after the insulation has been applied, B. Finding defects, such as line breaks, facilitates. Since the regenerated, red cellulose comes on the market as packing material in all colors, it is easier to distinguish between the conductors by means of different colored insulation. B. for reasons of taste, choose the color of the surroundings.
