Description

Vieladriges Schwachstromkabel. In dem Patent 393639 sind Maßnahmen angegeben, die bei vieladrigen Schwachstromkabeln der dort beschriebenen Bauart die durch die Anwendung verschiedener Schlaglängen verursachten Unterschiede der Kapazitätswerte dadurch beseitigen oder herabsetzen sollen, daß die Überlappung bzw. die Dicke der Papierbänder, aus welchen die Hüllen der Leitungen bestehen, j e nach der Schlaglänge verschieden groß bemessen wird. Die Erfindung beruht auf der Verringerung des Luftraumes in den Adern derjenigen Leitergruppen, die infolge der Schlaglängenverschiedenheit die kleinere Kapazität aufweisen. Der Ausgleich findet dadurch statt, daß die Kapazität der Leiterschleife mit längerem Schlag auf den größeren Wert der Kapazität der Leiterschleife mit kürzerem Schlag gebracht wird.Multi-core low-voltage cable. In the patent 393639 measures are taken indicated, for multi-core low-voltage cables of the type described there the differences in the caused by the use of different lay lengths Eliminate or reduce capacitance values by eliminating the overlap or the thickness of the paper tapes from which the sleeves of the cables are made, each is dimensioned differently according to the length of lay. The invention is based on the reduction of the air space in the veins of those groups of leaders who as a result the difference in lay length have the smaller capacity. The compensation takes place because the capacity of the conductor loop increases with a longer blow brought the greater value of the capacitance of the conductor loop with a shorter lay will.

Gemäß der vorliegenden Erfindung wird der Querschnitt des in der isolierten Hohlader eingeschlossenen Luftraumes dadurch verkleinert, daß der zusätzliche feste Isolierstoff nicht durch Verbreiterung der Überlappung oder Verdickung des Papiers aufgebracht wird, sondern durch Verwendung eines schmalen band- oder fadenförmigen Streifens aus festem Isolierstoff, welchen man entweder schraubenförmig um den nackten Leitungsdraht windet oder mit diesem zusammen der Länge nach gestreckt einlaufen läßt.According to the present invention, the cross section of the isolated Loose artery enclosed air space is reduced by the fact that the additional solid Do not use insulating material by widening the overlap or thickening the paper is applied, but by using a narrow ribbon or thread-like Strips of solid insulating material, which you either screw around the bare Conductor wire winds or runs in lengthways along with it leaves.

Die fabrikationsmäßige Trennung des zusätzlichen festen Isolierstoffes von der eigentlichen Aderhülle hat den Vorteil vereinfachter Herstellung, da es nicht nötig ist, zwei oder mehrere verschiedenartig beschaffene Adern herzustellen. Gleichzeitig dient der Einlauf in die Ader zur Kennzeichnung und zu Zählzwecken; er verhindert die Verwechslung der Adern, die mit verschiedenen Schlaglängen verseilt werden müssen.The production-related separation of the additional solid insulating material from the actual core sleeve has the advantage of simplified manufacture, since it it is not necessary to produce two or more differently designed cores. At the same time, the entry into the core serves for identification and counting purposes; it prevents the cores from being mixed up, which are stranded with different pitch lengths Need to become.
