Trvigt von der Gr;:sse des Schirmes ah, die "i^'i von Höhe der Arbeitsspnnnung abhängig ic-*« Ausserden .'.rt es gemüse Erfindung wesentlich von Vo:-+eil, daß ■•n Stamm des Tsolators rippenartige Gebilde angeformt werden. Diese "Rippen" sind scharfkantig und erstrecken sich in UmfangsrichtungoTrvigt of the Gr ; : sse of the screen ah, the "i ^ 'i depends on the level of the working voltage." According to the invention, it is essential that rib-like structures are formed on the trunk of the isolator "Ribs" are sharp-edged and extend circumferentially

Ein Beispiel einer konstruktiven Lösung von Stufen und "Rippen" gibt die Zeichnung. Die VTirkung der Stufen und. "Rippen" besteht darin, daß die scharfen Kanten die Fremdschicht der Verschmutzung unterbrechen und dadurch die Entladungen zerreissen. Dies hat einen grösseren Oberflächsnwiderstand und Erhöhung der Festigkeit gegen Kriechentladunifen zur Folge, ohne den Isolator zu vergrössern oder seine Schirmzahl zu vermehren« Dadurch ist die Wahrscheinlichkeit von Überschlägen und Störungen λ wesentlich vermindert, und zwar auch unter schweren atmosphärischen Bedingungen, z.l. bei Hebel, Tau und leichtem Regen. Die Anwendung der Stufen und "Rippen" erlaubt sogar eine Verminderung der Grosse, des Gewichtes und Preises des-Isolators*An example of a constructive solution of steps and "ribs" is given in the drawing. The Effect of Levels and. "Ribs" consists in the fact that the sharp edges interrupt the foreign layer of the pollution and thereby tear the discharges. This has to enlarge a greater Oberflächsnwiderstand and increasing strength against Kriechentladunifen result without the isolator or to increase his shield number "This is the probability of flashovers and faults λ substantially reduced, even under severe atmospheric conditions, zl at lever Tau and light rain. The use of the steps and "ribs" even allows the size, weight and price of the isolator to be reduced *
