Description

Isoliermasse zur Abdichtung elektrischer Leitungen und Kabel. Es ist bereits vorgeschlagen worden, die isolierten Drähte oder Litzen eines Kabels, das beständig oder zeitweilig unter Wasser liegt und dem Eindringen von Wasser ausgesetzt ist, in eine entsprechende Isoliermasse einzubetten und alle Hohlräume im Kabel mit solcher Masse auszufüllen. öle, Teer, Peche und Bitumina haben sich aber hierfür -nicht bewährt, weil sie von der eigentlichen Isolierung der Leiter, wie Gummi, Guttapercha, Papier, Faserstoff usw., aufgesaugt und verändert werden, so daß nach einer gewissen Zeit doch Lücken entstehen und die Massenihren Zweck nicht mehr erfüllen.Insulating compound for sealing electrical lines and cables. It is It has already been proposed to use the insulated wires or strands of a cable that is permanently or temporarily under water and exposed to ingress of water is to be embedded in a suitable insulating compound and all cavities in the cable to be filled in with such a mass. However, oils, tar, pitch and bitumina have been chosen for this -not proven because it depends on the actual insulation of the conductor, such as rubber, Gutta-percha, paper, fiber, etc., can be absorbed and changed so that after after a certain time gaps arise and the masses no longer serve their purpose.

Nach vorliegender Erfindung werden die einzelnen Drähte oder Litzen oder die fertigen Adern in eine klebrige Masse eingebettet, die alle Zwischenräume völlig ausfüllt, ihre Klebrigkeit nicht verliert und eine Vertiefung und Verbreitung des eindringenden Wassers im Kabel sicher ausschließt. Eingehende Versuche haben ergeben, daß sich hierzu klebrige, zähflüssige, balsamartige Massen eignen, beispielsweise alle synthetischen Kautschuke, die nur bis zu einem gewissen Grade polymerisiert sind, ferner alle Sorten von Naturkautschuk, Guttapercha, Balata oder Mischungen daraus, die durch Depolymerisation auf diesen Grad von Zähflüssigkeit gebracht sind. Diese werden von der eigentlichen Isolierung der Leiter nicht aufgesaugt oder verändert und bewahren auch dauernd ihre Klebrigkeit und wasserabstoßenden Eigenschaften.According to the present invention, the individual wires or strands or the finished veins embedded in a sticky mass, all of the gaps completely fills in, does not lose its stickiness and a deepening and spreading safely excludes the ingress of water in the cable. Have in-depth attempts show that sticky, viscous, balsamic masses are suitable for this purpose, for example all synthetic rubbers that only polymerize to a certain extent are, as well as all types of natural rubber, gutta-percha, balata or mixtures from it, which are brought to this degree of viscosity by depolymerization. These are not absorbed or changed by the actual insulation of the conductor and also permanently retain their tackiness and water-repellent properties.
