Abstract

It is provided in the case of a cable end termination that it is constructed in the shape of a cap, that it consists of insulating material, that it contains an electrically conductive mass which is in electrical contact with the conductor end and/or the screened end of the cable, and that a penetration (feedthrough) is provided which is in contact with the electrically conductive mass and serves the purpose of producing an electrical connection between the electrically conductive mass and the earth potential.

Description

Bei Starkstromkabeln besteht bekanntlich das Problem, daß das Kabel beim Verlegen durch Reibung aufgeladen wird. Dabei besteht die Gefahr, daß über eine Person eine Entla­ dung des Leiters und/oder Schirms des Kabels zur Erde er­ folgt. Dadurch kann ein unerwünschter Schreck ausgelöst werden, der möglichst verhindert werden soll.The problem with power cables is known to be that the cable is charged by friction during installation. There is a risk that a discharge over a person extension of the conductor and / or shield of the cable to earth follows. This can trigger an unwanted fright be avoided as much as possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Lösung die­ ses Problems anzugeben.The invention has for its object a solution problem.

Die Erfindung wird im folgenden an einem Ausführungsbei­ spiel erläutert:The invention is illustrated below in one embodiment game explained:

Ein Starkstromkabel besteht gemäß Fig. 1 im allgemeinen aus einem Leiter 1, einer Isolierung 2, einem Schirm 3 und einem Außenmantel 4. Der Leiter 1 besteht beispielsweise aus Kupfer oder Aluminium. Die Isolierung 2 besteht bei­ spielsweise aus VPE oder PVC. Der Schirm 3 besteht bei­ spielsweise aus Kupferdrähten oder Kupferbändern. Bei Ver­ wendung von Kupferdrähten für den Schirm werden diese durch Querleitbänder miteinander elektrisch verbunden. Besteht der Schirm des Kabels aus Kupferbändern, so sind die Kupfer­ bänder so aufgebracht, daß sie sich überlappen. Wird der Außenmantel 4 beim Verlegen gerieben, so entsteht durch die mechanische Reibung eine statische Ladung auf dem Außen­ mantel 4, die eine Ladung auf dem Schirm 3 bzw. Leiter 1 induziert. Kommt eine Person beim Verlegen des Kabels mit dem Leiter 1 oder Schirm 3 in Berührung, so wird die Ladung auf dem Schirm 3 oder Leiter 1 in unerwünschter Weise über die Person zur Erde abgeleitet.A power cable is shown in FIG. 1 is generally made of a conductor 1, an insulator 2, a screen 3 and an outer jacket 4. The conductor 1 consists, for example, of copper or aluminum. The insulation 2 consists, for example, of XLPE or PVC. The screen 3 consists, for example, of copper wires or copper strips. If copper wires are used for the screen, these are electrically connected to one another by cross conductors. If the shield of the cable consists of copper strips, the copper strips are applied so that they overlap. If the outer sheath 4 is rubbed during installation, the mechanical friction creates a static charge on the outer sheath 4 , which induces a charge on the screen 3 or conductor 1 . If a person comes into contact with conductor 1 or screen 3 when laying the cable, the charge on screen 3 or conductor 1 is undesirably discharged to earth via the person.

Um diesen unerwünschten Effekt zu vermeiden, wird gemäß der Erfindung nach den Fig. 1 und 2 auf das Kabel an seinem Ende eine Isolierkappe 5 aufgebracht, die mit einer leit­ fähigen Masse 6 ausgefüllt ist. Die leitfähige Masse 6, die z. B. aus leitendem Silicongummi besteht, steht mit dem Leiterende und dem Schirmende des Kabels in Verbindung. Gemäß der Erfindung ist eine Durchführung 7 vorgesehen, die mit der leitenden Masse 6 elektrisch leitend ver­ bunden ist und die Ladung vom Leiter 1 und/oder Schirm 3 des Kabels über die leitende Masse 6 nach außen abführt. Die Kappe 5 ist beispielsweise so ausgebildet, daß sie mach dem Aufbringen auf das Kabel im Preßsitz auf dem Ka­ bel aufsitzt. Die Kappe kann auch mit dem Kabel (zusätzlich) verklebt sein, und zwar nach der Fig. 2 mittels der Klebemasse 8.In order to avoid this undesirable effect, an insulating cap 5 is applied to the cable at its end according to the invention according to FIGS. 1 and 2, which is filled with a conductive mass 6 . The conductive mass 6 , the z. B. consists of conductive silicone rubber, is connected to the conductor end and the shield end of the cable. According to the invention, a bushing 7 is provided which is electrically conductively connected to the conductive mass 6 and discharges the charge from the conductor 1 and / or screen 3 of the cable via the conductive mass 6 to the outside. The cap 5 is, for example, designed so that it mach the application on the cable in the press fit on the Ka bel. The cap can also (additionally) be glued to the cable, specifically according to FIG. 2 by means of the adhesive 8 .

Die Durchführung 7 besteht beispielsweise aus einem Gewinde­ bolzen, der durch eine Öffnung in der Kappe 5 in das Kappen­ innere geführt ist und mit der Kappe 5 wasserdicht ver­ schraubt ist. Das Ende der Durchführung 7 steht mit der leitenden Masse 6 in elektrischer Verbindung. Die Öse 9 am einen Ende der Durchführung 7 dient zum Anschließen des Erdpotentials.The implementation 7 consists, for example, of a threaded bolt which is guided through an opening in the cap 5 into the inner cap and is screwed to the cap 5 in a watertight manner. The end of the bushing 7 is in electrical connection with the conductive mass 6 . The eyelet 9 at one end of the bushing 7 is used to connect the earth potential.
