Description
Kabelendverschluß für feuchte Innenräume und Freiluftaufstellung Es ist bereits eine Ausführungsform eines Kabelendverschlusses bekanntgeworden, bei dem die abgehenden Adern, um das Ausfließen der Kabeltränkmasse zu verhindern, mit elastischen Isolierschläuchen geschützt sind, die an ihren Enden mit kurzen Bandagierungen, Stopfbuchsen o. dgl. abgedichtet sind. - Diese Ausführungsform wird jedoch nicht für Kabelendverschlüsse angewandt, die in feuchten Innenräumen oder im Freien aufgestellt werden sollen, da die Gefahr besteht, daß die elastischen Isolierschläuche unter dem Einfluß der Witterung bald eine beträchtliche Oberflächenleitfähigkeit annehmen, die Überschläge zur Folge haben kann. Die Erfindung vermeidet diesen Nachteil und besteht darin, daß auf den elastischen Isolierschläuchen Isolierstoffringe in Abständen angeordnet sind. Durch diese Maßnahme werden die Kriechwegwiderstände vergrößert, so daß die Gefahr von Überschlägen auch dann noch gering ist, wenn der elastische Werkstoff bereits eine beträchtliche Isolationsverschlechterüng erlitten hat. Die Isolierstoffringe werden zweckmäßig aus Porzellan hergestellt, aber auch andere Isolierstoffe, z. B. Kunstpreßstoffe o. dgl., die entsprechend kriechwegfest sind oder durch Oberflächenbehandlungkriechwegfest gemacht worden sind, können dazu verwendet werden.Cable termination for damp interiors and outdoor installation Es an embodiment of a cable termination has already become known at with the outgoing cores to prevent the cable draining compound from flowing out elastic insulating hoses are protected, which at their ends with short bandages, Stuffing boxes or the like are sealed. - However, this embodiment will not Applied for cable terminations that are installed in damp interiors or outdoors should be, as there is a risk that the elastic insulating tubes under soon assume a considerable surface conductivity due to the influence of the weather, which can result in rollovers. The invention avoids this disadvantage and consists in that on the elastic insulating tubes insulating rings at intervals are arranged. This measure increases the creepage resistance, so that the risk of flashovers is still low even if the elastic Material has already suffered a considerable deterioration in insulation. the Insulating rings are expediently made of porcelain, but also others Insulating materials, e.g. B. plastics o or made creep-resistant by surface treatment can be used for this purpose will.
In der -Zeichnung ist die Erfindung an einem Ausführungsbeispiel eines Kabelendverschlusscs für ein dreiadriges Kabel dargestellt. Die aus der Aufteilungskappe r austretenden Kabeladern sind mit je einem elastischen Isolierschlauch 2 aus synthetischem Kautschuk umgeben. Diese elastischen Isolierschläuche sind an ihren Enden mit den Bandagierungen 3 und 4 versehen. Die Vergrößerung des Kriechwegwiderstandes erfolgt erfindungsgemäß durch die Porzellankörper 5, die in die elastischen Schläuche einvulkanisiert sind. Die abgehenden Leiter sind mit 6 bezeichnet.In the drawing, the invention is based on an exemplary embodiment of a Cable termination cs shown for a three-core cable. The one from the distribution cap r emerging cable cores are each with an elastic insulating tube 2 made of synthetic Surrounded by rubber. These elastic insulating hoses are at their ends with the Bandages 3 and 4 provided. The creepage resistance is increased according to the invention by the porcelain body 5, which is vulcanized into the elastic hoses are. The outgoing conductors are labeled 6.
Die Erfindung ist nicht auf das Ausführungsbeispiel beschränkt, sie kann für Kabel mit einer beliebigen Anzahl von Adern anjgewendet werden, insbesondere auch für Kabel mit einer einzigen Ader. Die Isolierstoffkörper erhalten die üblichen, für Isolatoren angewandten Ausbildungsformen, z. B. können sie glockenförmig ausgestaltet werden. Statt aus synthetischem Kautschuk können die elastischen Isolierschläuche auch aus einem anderen künstlichen elastischen Stoff oder auch aus natürlichem Gummi hergestellt sein.The invention is not limited to the exemplary embodiment, they can be used for cables with any number of cores, in particular also for cables with a single core. The insulating bodies receive the usual, Forms of training used for isolators, e.g. B. they can be designed bell-shaped will. Instead of synthetic rubber, the elastic insulating hoses also from another artificial elastic material or from natural rubber be made.
