Description

Eis ist bekannt, Endverschlüsse, Verbindungsmuffen od. dgl. für elektrische Kabel und Leitungen aus härtbaren oder selbsthärtenden Isolierstoffmassen, insbesondere aus Gießharzen auf der Basis von Äthoxylinharzen, herzustellen. Bei Kabeln und Leitungen mit Kunststoffisolierung, insbesondere auf der Basis von Polyvinylchlorid, wurden bisher aus verschiedenen Gründen bei der Verwendung von EndverschlÜBsen und Verbindungsmuffen aus Gießharzen keine brauchbaren Ergebnisse erzielt. Einerseits lag dies an der mangelnden Haftfestigkeit der Gießmasse auf der Kunststoffisolierung, andererseits konnte durch die hohe Härtungstemperatur mancher Harze nicht der gewünschte Erfolg erzielt werden, da die Polyvinylchloridumhülhing diese Temperatur nicht aushält.Ice cream is known, terminations, connecting sleeves Od. Like. For electrical cables and lines made of curable or self-curing insulating materials, in particular from casting resins based on ethoxylin resins. With cables and wires with Plastic insulation, in particular based on polyvinyl chloride, have hitherto been made of various Reasons for using end closures and connecting sleeves made of casting resins are not useful Results achieved. On the one hand, this was due to the lack of adhesive strength of the casting compound on the Plastic insulation, on the other hand, could not due to the high curing temperature of some resins Desired success can be achieved because the polyvinyl chloride coating cannot withstand this temperature.
Gemäß der Erfindung werden die genannten Nachteile dadurch beseitigt, daß die mit kalthärtenden Gießharzen abzuschließenden Teile der kunststoffisolierten Leitungen bzw. Kabel mindestens teilweise einen Überzug aus einem Klebemittel aufweisen, der auf der Basis von Polyvinylmischpolymerisaten., z. B. löslichen Mischpolymerisaten von Vinylchlorid und Vinylacetat, besteht.According to the invention, the disadvantages mentioned are eliminated in that with the cold-curing Cast resin parts of the plastic-insulated lines or cables at least partially have a coating of an adhesive based on polyvinyl copolymers., z. B. soluble copolymers of vinyl chloride and vinyl acetate.
Es eignen sich auch Klebemittel auf der Basis von Polyadditionsverbindungen, beispielsweise aus Polyesterharzen, die mit Isocyanatgruppen vernetzt sind. Die erfindungsgemäße Ausbildung ermöglicht es, in einfachster Weise für mit Polyvinylchlorid isolierte Leitungen und Kabel kalthärtende Gießharze zu verwenden. Es wird eine innige A^erbindung zwischen dem Gießharz und der Kunststoffisolierung auf Polyvinylchloridbasis gewährleistet. Es ist nicht unbedingt erforderlich, alle mit dem Gießharz zu bedeckenden Teile der Leitungen vorher mit dem Klebemittel zu bestreichen. Es genügt auch, wenn nur einzelne Teile mit dem Klebemittel bestrichen werden, um eine ausreichende Haftfestigkeit und absolute Abdichtung gegen Feuchtigkeit zu erzielen. Wenn beispielsweise einzelne Teile des Endverschlusses oder der Verbindungsmuffen durch mechanische Beanspruchung beschädigt werden, kann eine nachträgliche zuverlässige Reparatur vorgenommen werden, da nur die beschädigten Teile zu erneuern sind. Es bleiben immer noch Parzellen von ausreichender Festigkeit bestehen, zwischen denen eine Erneuerung des Gießharzes möglich ist. Die erfindungsgemäße Verwendung des Klebemittels verbessert nicht nur die Haftfestigkeit, sondern erhöht auch die Biegefestigkeit der einzelnen zu verbindenden bzw. abzuschließenden Teile der Leitungen bzw. Kabeladern. Es ist auch vorteilhaft, auf einzelnen Abschnitten der mit Klebemitteln versehenen Teile ringförmige Teile aus Gewebeband aufzubringen. Adhesives based on polyaddition compounds, for example made of polyester resins, are also suitable, which are crosslinked with isocyanate groups. The inventive training makes it possible in Easiest way to use cold-curing casting resins for lines and cables insulated with polyvinyl chloride. There is an intimate bond between the casting resin and the plastic insulation based on polyvinyl chloride guaranteed. It is not absolutely necessary to cover all of them with the casting resin Coating parts of the lines with the adhesive beforehand. It is also sufficient if only individual parts can be coated with the adhesive to ensure sufficient adhesive strength and absolute sealing to achieve against moisture. For example, if individual parts of the end closure or the connecting sleeves damaged by mechanical stress, a subsequent reliable Repair must be carried out as only the damaged parts need to be replaced. It still remains Plots of sufficient strength exist, between which a renewal of the cast resin is possible is. The use of the adhesive according to the invention not only improves the adhesive strength, but also improves the adhesive strength also increases the flexural strength of the individual parts of the lines to be connected or terminated or cable cores. It is also advantageous to apply adhesive to individual sections of the Parts to apply ring-shaped parts made of fabric tape.

It is also possible to add agents to the casting resin, for example plasticizers containing chillers or mineral fillers, which reduce the flammability.
