Description

Tiefsee-Fernsprechkabel Zusatz zum Patent 590 904 Das Hauptpatent betrifft ein Tiefsee-Fernsprechkabel mit einem aus trapez- .oder siektorförmig.en Formsträngen bestehenden Druckschutz und' einem diesen umschließenden Bleimäntel, bei welchem diese Formstränge, aus Guttapercha bestehend, sich zu einem Vollseil ergänzen und die papierisolierten Adern in die Nuten der Berührungsflächen der Formstränge mit Spieleingelegt sind.Deep sea telephone cable Addendum to patent 590 904 The main patent relates to a deep sea telephone cable with a pressure protection consisting of trapezoidal the paper-insulated wires are inserted into the grooves of the contact surfaces of the molded strands with play.

Zugrunde lag dieser Erfindung die Erkenntnis, daß Guttapercha trotz ihres geringen Widerstandes gegen einseitigen Druck, der ein Ausweichen des .Stoffes nach deal anderen Seiten hervorruft, eine sehr hohe Widerstandsfähigkeit gegen allseitigen Druck, Kompressionsfestigkeit besitzt, so daß sie geeignet ist, auch bei den höchsten Wasserdrücken, wie sie in der Tiefsee auftreten, eine Einbettung der Adern in die aus den Nuten gebildeten Kanäle zu gestatten, ohne daß durch Zusammendrückung der Kanäle die Papierluftisolierung Schaden leidet.This invention was based on the knowledge that gutta-percha despite their low resistance to one-sided pressure, which allows the material to evade after deal evokes other sides, a very high resistance to all-round Pressure, has compressive strength, so it is suitable even at the highest Water pressures, as they occur in the deep sea, an embedding of the veins in the To allow channels formed from the grooves without the compression of the Ducts the paper air insulation suffers from damage.

Es ist nun erkannt worden, daß statt der teueren Guttapercha auch Gummi verwendbar ist. Versuche haben gezeigt, daß ein aus vier mit Nuten versehenen. Gummisträngen, die zu einem Vollseil von 3o mm Durchmesser zusaimmengeschlossen und mit einem Bleimantel umgeben waren, zusammengesetztes Kabel bei Drücken von mehreren ioo Atmosphären nur eine. so geringe Verminderung der Kanaldurchmesser aufwies, daß der Luftspielraum von reingelegten papierisolierten Adern nicht beeinträchtigt worden wäre.It has now been recognized that instead of the expensive gutta-percha also Rubber is usable. Tests have shown that one out of four grooved. Strands of rubber that are joined together to form a solid rope with a diameter of 30 mm and surrounded with a lead jacket, composite cable when pressed several ioo atmospheres only one. so little reduction in channel diameter showed that the air clearance is not impaired by laid paper-insulated cores would have been.

Die Verwendung von Gummi hat vor derjenigen von Guttapercha nicht nur den Vorzug der Billigkeit, sondern auch der größeren Biegsamkeit, was die Verlegung des Kabels bedeutend erleichtert. Auch kann auf die Verwendung von Guttapercha verzichtet werden, da die Formstränge durch den Bleimantel gegen die Einwirkung des Seewassers geschützt sind.The use of gum has not preceded that of gutta-percha only the merit of cheapness, but also greater flexibility, what the laying of the cable much easier. The use of gutta-percha can also be dispensed with because the form strands are protected by the lead coating against the action of the sea water are protected.
