  Stützisolator. 



   Es ist bekannt, Stützisolatoren für hohe Spannungen, die zylindrisch oder konisch geformte   hohle Rotationskörper darzustellen pflegen, innen mit einem isolierenden Stoff auszugiessen, zu dem Zweck   die hohe Beanspruchung, der die Luft im Innern des Isolators ausgesetzt sein würde, zu vermeiden. Diese hohe Beanspruchung erstreckt sich aber nicht gleichmässig über das ganze Innere des Isolators, sondern sie ist am grössten in unmittelbarer Nähe der spannungsführenden Teile am Kopf des Isolators und wird nach dem geerdeten Fuss zu immer kleiner. Es würde also genügen, wenn man nur in der Gegend der höchsten Beanspruchung, also am Kopf, die Luft durch ein besseres Isoliermaterial ersetzt. 



   Eine solche Anordnung ist der Gegenstand der vorliegenden Erfindung. Die Trennung des eingegossenen Isolierstoffes (z. B. Kompound) von der Luft erreicht man erfindungsgemäss durch einen senkrecht zur Achse angeordneten Steg. Die Vorteile dieses Stützisolators liegen vor allem in der Ersparnis eines grossen Teiles des hochwertigen   Ausgussgutes,   ohne dadurch die durch die bisher bekanntgewordenen Isolatoren mit völlig ausgegossenem Innern erzielten, Wirkungen irgendwie zu   beeinträchtigen.   Ein solcher Isolator ist in der Zeichnung dargestellt. Der Steg b ist gleichzeitig mit dem eigentlichen Isolator a hergestellt. Diese   Ausführungsform   ist bei Isolatoren aus keramischen Stoffen   zweckmässig.   Bei solchen

  Post insulator.



   It is known that post insulators for high voltages, which are cylindrical or conically shaped hollow bodies of revolution, are poured inside with an insulating material for the purpose of avoiding the high stress that the air inside the insulator would be exposed to. This high load does not extend evenly over the entire interior of the insulator, but is greatest in the immediate vicinity of the live parts on the head of the insulator and becomes smaller and smaller after the grounded foot. It would be sufficient if the air was replaced by a better insulating material only in the area of the highest stress, i.e. on the head.



   Such an arrangement is the subject of the present invention. The separation of the cast-in insulating material (e.g. compound) from the air is achieved according to the invention by a web arranged perpendicular to the axis. The advantages of this post insulator are primarily the saving of a large part of the high-quality pouring material, without in any way impairing the effects achieved by the previously known insulators with completely poured interior. Such an isolator is shown in the drawing. The web b is produced at the same time as the actual insulator a. This embodiment is useful for insulators made from ceramic materials. In such
