Description

  

  Verfahren zum feuersicheren Isolieren     elektrischer    Leiter.    zeichnet, dass die Isolation aus Glasfäden er  stellt wird.  



  Dadurch werden die beschriebenen Nach  teile verkleinert. Glas ist     bekanntlich    ein  guter Isolator, nicht     brennbar    und in Form  von Fäden,     sogenanuter    Glaswolle, biegsam  und spinnbar. Beispielsweise lässt es sich so  mit in ähnlicher Weise wie Seide oder Baum  wolle zum Isolieren von     -Wicklungs-    und In  stallationsdrähten verwenden.    Ist die Isolation eines elektrischen Leiters  gegen Wärme nicht beständig (zum Beispiel  brennbar oder     verkohlbar),    so darf die Strom  stärke im letzteren einen bestimmten Wert  nicht überschreiten.

   Dieser Umstand ist also  die Ursache von Gefahren, sowie der Grund,  dass die     Belastungs-    und Verwendungsmög  lichkeit von Installationen, Apparaten, Mo  toren     etc.    begrenzt ist, was auch die Rendite  ungünstig beeinflusst. Anderseits kann man  bis jetzt feuerbeständiges Material nicht  überall mit Erfolg verwenden, zum Beispiel  da nicht, wo die Isolation biegsam sein sollte  (Isolieren von Drähten).  



  Gegenstand     vorliegender    Erfindung bil  det nun ein     Verfahren    zum feuersicheren Iso  lieren elektrischer Leiter, dadurch gekenn-



  Method of fire-proof insulation of electrical conductors. draws that the insulation is made of glass threads.



  As a result, the described after parts are reduced. Glass is known to be a good insulator, non-flammable and in the form of threads, so-called glass wool, pliable and spinnable. For example, it can be used in a manner similar to silk or cotton for insulating winding and installation wires. If the insulation of an electrical conductor is not resistant to heat (e.g. combustible or charring), the current in the latter must not exceed a certain value.

   This circumstance is therefore the cause of dangers, as well as the reason that the load and use possibilities of installations, apparatus, motors, etc. is limited, which also has an unfavorable effect on the return. On the other hand, up to now fire-resistant material cannot be used with success everywhere, for example not where the insulation should be flexible (insulation of wires).



  The present invention now forms a method for fire-proof insulation of electrical conductors, thereby
