Description

Verfahren zur Herstellung von Verbindungsstellen in der Isolation von elektrischen Seekabeln Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Verbindungsstellen in der Isolation von elektrischen Seekabeln, die mit Guttapercha oder guttaperchaähnlichen Stoffen isoliert sind. Die Herstellung derartiger Isolationsverbindungsstellen ist eines der schwierigsten Probleme der Seekabelfabrikation überhaupt. Während bei Guttaperchakabeln die Herstellung der Verbindungsstellen von Facharbeitern mit der Hand ausgeführt werden kann, mußte für die Verbindung von Adern mit einer Isolation aus güttaperchaähnlichen Stoffen, wie Paragutta, ein besonderes Verfahren ausgearbeitet und eine besondere Maschine konstruiert werden, um eine einwandfreie Haftung der einander überlappenden Flächen zu erzielen. Die Herstellung vollkommen einwandfreier Verbindungsstellen in Paraguttaadern von Hand gelang bisher nicht.Process for the production of connection points in the insulation of submarine electrical cables The invention relates to a method of manufacture of junctions in the insulation of submarine electrical cables made with gutta-percha or gutta-percha-like substances are isolated. The manufacture of such insulation joints is one of the most difficult problems in the manufacture of submarine cables. While in the case of gutta-percha cables, the production of the connection points by skilled workers the hand can be done, had to connect wires with an insulation A special process was worked out from substances similar to Gütta-percha, such as paragutta and a special machine designed to ensure proper adhesion of the to achieve overlapping surfaces. The production perfectly flawless Connection points in Paragutta veins by hand have not yet been successful.

Es wurde nun gefunden, daß man auch ohne besondere Vorrichtungen eine. einwandfreie wasserdichte Verbindungsstelle in der Isolation von Paraguttaadern herstellen kann, wenn man als Verbindungsmaterial eine an sich bekannte Mischung von Guttapercha, Balata o. dgl. mit Polystyrol oder ähnlichen Kunststoffen verwendet. Das Haftvermögen und die Klebekraft einer Mischung von beispielsweise S 5 °/a @entharzter Balata mit 15 Polystyrol ist so groß, daß unter allen Umständen eine einwandfreie und wasserdichte Verbindungsstelle bei Paraguttaadern zustande kommt. Will man den Prozentsatz des Polystyrols in der Mischung erhöhen, um die Klebekraft noch weiter zu steigern, so empfiehlt es sich, der Mischung Wachs, Kautschuk oder andere Erweichungsmittel auf bekannte Weise beizumengen, da anderenfalls die Gesamtmischung zu hart wird.It has now been found that even without special devices one. Perfect watertight connection point in the insulation of Paragutta veins can be produced if a known mixture of gutta-percha, balata or the like with polystyrene or similar plastics is used as the connection material. The adhesion and the adhesive force of a mixture of, for example, S 5 ° / a @entharzter Balata with 1 5 polystyrene is so great that a satisfactory and water-tight joint at Paraguttaadern comes into being under all circumstances. If you want to increase the percentage of polystyrene in the mixture in order to increase the adhesive strength even further, it is advisable to add wax, rubber or other emollients to the mixture in a known manner, otherwise the total mixture will be too hard.

Auch bei der Herstellung von Verbindungsstellen in Guttaperchaadern bietet die Verwendung der obengenannten Mischungen dieselben Vorteile, da diese Mischungen sich besser verarbeiten lassen als Guttapercha allein.Also in the production of connection points in gutta-percha veins the use of the above mixtures offers the same advantages as these Mixtures are easier to process than gutta-percha alone.

Aus dem Vorstehenden ergibt sich, daß sich das Verfahren gemäß der Erfindung für die Herstellung der Verbindungsstellen bei den verschiedensten thermoplastischen Seekabelisoliermaterialien besonders gut eignet. Daraus folgt, daß im allgemeinen Isoliermaterial und Verbindungsmaterial ihrer Zusammensetzung .nach nicht übereinstimmen werden, obwohl gerade darauf bisher besonderer Wert gelegt worden ist, und daß das Material insbesondere auch bei Instandsetzungen von älteren Seekabeln vorteilhaft Verwendung finden kann.From the above it follows that the method according to the Invention for the production of the joints in a wide variety of thermoplastic Submarine cable insulation materials are particularly suitable. It follows that in general Insulating material and connecting material do not match their composition even though special importance has been attached to this up to now, and that that Material particularly advantageous when repairing older submarine cables Can be used.
