Der Erfindung liegt die _sufgabe zugrunde, den Einfluß- der porigen Struiitur der Aluminiumoxidschicht sowie der Schvrachstellen und der bei Verformbeanspruchungen :@uftretenden Risse durch geeignete Maßnahmen zu beheben. Erfindungsgemäß wird die -Aufgabe dUdurch gelöst, dz ß: die Poren und Risse--der Aluminiumoxidschicht mit einem niedrig viskosen niclithärtbaren Sililionnrodukt, vorzugs::@e..se Silikonölt deren wässrige #,'mulsionen oder Silikonfette oberhalb ihres 'rr-seicliun#s?ounktes, ausgefüllt sind.The invention is based on the task of controlling the porous Structure of the aluminum oxide layer as well as the weak points and the deformation stresses : @fix any cracks that occur by taking suitable measures.

Die Imprägnierung der z;luminiumleitermaterialien Erfolgt in techmlogisch bekannter ,:eise.The impregnation of the aluminum conductor materials takes place technologically better known: ice.
Um den Ein%luß der Risse in der Aluminiumoxdschicat, die bei der Verarbeitung der Leitermaterialien entstehen' sicher zu beheben, ist es zweckmäßig, die Ir_,orügnierung unmittelbar vor oder nach-der Verarbeitung vorzunehmen. Die Erfindung zeichnet sich dadurch aus, daß ein Schichtd@ckenzuwachs vermieden wird:. Die Imprägnierung bleibt -bei Verformbeanspruchungen voll erhalten und die Isolation ist feuchtigkeitsbeständig" wodurch die Durchsc'11agfestigket unveränderlich ist.Around the one percent of the cracks in the aluminum oxjicate that occurred during processing When the conductor materials arise, it is advisable to fix them safely immediately before or after processing. The invention stands out in that an increase in layer thickness is avoided: The impregnation remains - fully preserved in the event of deformation stresses and the insulation is moisture-resistant " whereby the average strength is unchangeable.
Der technologische Aufwand ist ein geringer.The technological effort is less.
Die niedrig viskosen Silikonnrodukte bieten ebenso den' Vorteil, daß sie sich leicht reit Füllstoffen zur Anpassung der elektrischen Eigenschaften versetzen lassen.The low-viscosity silicone products also have the advantage that they can easily be added to fillers to adapt the electrical properties.
