Description
Die Leitungen werden aus diesen Gründen mit besonderen Uberwachungseinrichtungen
(Schutzrelais) verbunden, die bei'. Eintreten eines Fehlers im Schutzmantel oder
in der Isolierung die Leitung unverzüglich abschalten, bevor Funkenbildungen entstehen
können. Die in den Zwickelräumen liegenden leitgummiumhüllten Hilfsleiter können
je nach den vorliegenden Verhältnissen und den jeweils benutzten überwachungseinrichtungen
als besondee Steueradern und/oder als zusätzliche Längsdrähte zur Vergrößerung der
Leitfähigkeit der Leitgummischichten dienen, an die die Überwachungseinrichtungen
angeschlossen werden. Ferner
Die Leitung nach der, Fig. 1 besteht aus vier um einen Profilkern
10 aus einem gummiartigen Isolierstoff verdrillten Adern, von
Nach dem Ausführungsbeispiel gemäß der Fig. 2 sind drei Hauptadern einzeln mit einer Leitgummischicht 20 versehen und in schraubenförmig verlaufenden Rillen eines. Profilkerns 21 aus Leitgummi angeordnet. Der Erd-bzw. Schutzleiter wird bei dieser Ausführung durch zwei Teilleiter 22 gebildet, : die einzeln mit der Isolierung 23 und der Leitgummischicht 24 umhüllt und in zwei Zwickelräumen angeordnet sind. Im dritten Zwickelraum liegen zwei leitgummitumhüllte Leiter 25, die miteinander verdrillt und mit der gemeinsamen Leitgummischicht 26 bedeckt sind.According to the embodiment shown in FIG. 2, there are three main cores individually provided with a conductive rubber layer 20 and in helical Grooving one. Profile core 21 arranged from conductive rubber. The earth or. Protective conductor is formed in this embodiment by two sub-conductors 22: the individually with the insulation 23 and the conductive rubber layer 24 and wrapped in two interstices are arranged. In the third interstice there are two conductive rubber-coated conductors 25, which are twisted together and covered with the common conductive rubber layer 26.
Die in der Fig. 3 dargestellte Leitung besteht unter Weglassung
Die Neuerung ist nicht auf die angegebenen Ausführungsformen beschränkt.
Beispielsweise können bei der Ausführungsform nach
Über der neuerungsgemäß ausgebildeten Leitgummischicht kann unter Zufügung einer gummiartigen Isolierschicht noch eine weitere leitende Schicht (Schirmschicht) angeordnet sein, worüber dann der Außenmantel folgt.Over the newly designed conductive rubber layer can under Addition of a rubber-like insulating layer yet another conductive layer (shield layer) be arranged, what then follows the outer jacket.
