Description
Verfahren zur Herstellung eines längswasserdichten Leiterseiles für elektrische Kabel Die Erfindung betrifft ein Verfahren zur Herstellung eines längswasserdichten Leiterseils für elektrische Kabel mit einem die Lücken zwischen den Drähten ausfüllenden Dichtungsmittel.Process for the production of a longitudinally watertight conductor cable for electrical cables The invention relates to a method for producing a longitudinally watertight cable Conductor rope for electrical cables with one to fill the gaps between the wires Sealant.
Die stromführenden Leiter eines elektrischen Kabels oder einer Leitung bestehen bekanntlich aus verseilten Drähten. Zwischen den Drähten sind Hohlräume vorhanden. Sie wirken als Kapillaren. Denn sie leiten im Schadensfall die in das Kabel eindringende Feuchtigkeit von der Schadenstelle aus längs des Leiterseils im Kabel weiter. Diese Kapillarwirkung der Hohlräume im Leiterseil ist bei den sogenannten längswasserdichten Kabeln verhindert oder gemindert. Bei diesen ist das Leiterseil dadurch längswasserdicht gemacht, daß ein Dichtungsmittel vor der Verseilung der Drähte zum Leiterseil auf die Drähte aufgebracht wird und die Drähte dann dicht aneinanderliegend miteinander verseilt werden, damit das Dichtungsmittel in die Zwickelräume zwischen den Drähten eindringt und sie, vollständig ausfüllt. Oder es wird das Dichtungsmittel während des Verseilvorganges in die Zwickelräume zwischen den Drähten eingebracht.The current-carrying conductors of an electrical cable or line are known to consist of stranded wires. There are voids between the wires available. They act as capillaries. Because in the event of damage, they direct the into the Moisture penetrating the cable from the damaged area along the conductor cable in the cable. This capillary action of the cavities in the conductor cable is the so-called longitudinally watertight cables prevented or reduced. With these is the conductor rope made longitudinally watertight by applying a sealant prior to stranding the Wires to the conductor are attached to the wires and the wires are then sealed are stranded together so that the sealant in the Penetrates interstices between the wires and completely fills them. or it becomes the sealant during the stranding process in the interstices between introduced the wires.
Man hat auch schon das Leiterseil vor dem Bedecken mit der Isolierhülle mit einer Masse getränkt, die in die Hohlräume eindringen und sie verschließen soll. Dabei ist es jedoch nicht gelungen, das Leiterseil vollständig mit der Masse abzudichten. Ein derartiges Leiterseil besteht im allgemeinen aus einer Anzahl von gleich dicken, runden Drähten, die in einer oder mehreren Lag-en über einem zentralen Kerndraht angeordnet sind. Dabei besteht die erste, auf dem Keirndraht angeordnete Lage aus sechs Drähten, und jede folgende Lage ist jeweils um weitere sechs Drähte vermehrt. Diese Drähte liegen bei diesem Leiteraufbau dicht an- und übereinander und lassen zwischen den Drähten die dreieckförinigen Zwickelräume, in die die Dichtungsmasse beim Tränkvorgang nicht eindringen kann.You also have the conductor before covering it with the insulating sleeve soaked with a mass that is supposed to penetrate the cavities and seal them. However, it was not possible to completely seal the conductor cable with the mass. Such a conductor cable generally consists of a number of equal thicknesses, round wires in one or more layers over a central core wire are arranged. The first layer arranged on the wedge wire consists of six wires, and each subsequent layer is increased by a further six wires. In this conductor structure, these wires lie close to and on top of each other and leave between the wires are the triangular interstices in which the sealant is placed cannot penetrate during the soaking process.
Aufgabe der Erfindung ist es, ein Verfahren zu entwickeln, das die Ausfüllung sämtlicher Zwickelräume in dem Leitungsseil ermöglicht, um dieses längswasserdicht zu machen. Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß das Seil mit offenen Drahtlagen hergestellt und das fertige Seil mit dem Dichtungsmittel behandelt wird. Das Leiterseil ist also abweichend von dem üblichen Seilaufbau so aufgebaut, daß zwischen je zwei in einer Lage angeordneten Drähten ein Zwischenraum vorhanden ist, der das Eindringen der Füllmasse erleichtert. Dieser Zwischenraum zwischen den Drähten kann erzielt werden, indem der Kerndraht etwas dicker als die Drähte der darüber befindlichen Lage bzw. Lagen gemacht wird. Diesen Seilaufbau zeigt Fig. 1. Es kann aber auch die Anzahl der Drähte jeder Lage wenigstens um einen Draht in jeder Lage verringert werden.The object of the invention is to develop a method which enables all interstices in the line rope to be filled in order to make it longitudinally watertight. This aim is achieved according to the invention in that the rope is produced with open wire layers and the finished rope is treated with the sealing agent. In contrast to the usual structure of the cable, the conductor cable is constructed in such a way that there is an intermediate space between each two wires arranged in a layer, which space facilitates the penetration of the filling compound. This gap between the wires can be achieved by making the core wire slightly thicker than the wires of the layer or layers above it. This cable structure is shown in FIG. 1. It is also possible, however, to reduce the number of wires in each layer by at least one wire in each layer.
Durch die so erzielten Zwischenräume zwischen den Drähten kann die Füllmasse wesentlich besser in die Zwickelräume des Seils eindringen und diese ausfüllen als bei den in der üblichen Weise aufgebauten Seilen.Due to the spaces between the wires achieved in this way, the Filling compound penetrate much better into the interstices of the rope and fill them up than with ropes built in the usual way.
Zum Ausfüllen der Zwickelräume des Leiterseils kann gegebenenfalls eine aufschäumbare Masse verwendet werden, die nach dem Aufbringen auf dem Leiterseil aufschäumt und die Zwickelräume ausfüllt (Fig. 2).To fill in the interstices of the conductor cable, if necessary a foamable mass can be used after application on the conductor foams up and fills the interstices (Fig. 2).
