PATENTAMPATENTAM
Um Telegraphenkabel soviel als möglich mit Luft zu umgeben, und Unterseekabel, welche starken Druck auszuhalten haben, sehr widerstandsfähig zu machen, wird der Kabelkern so angeordnet, dafs er mit seiner Schutzhülle so wenig als möglich in Berührung kommt, und zu diesem Zweck wird derselbe, statt frei in der. Schutzhülle zu liegen, mit aus der Mittelachse heraustretenden Stellen versehen, beispielsweise in Wellenform, Zickzackform u. s. w. gebracht, derart, dafs er die Schutzhülle nur mit seinen vortretenden Stellen berühren kann, wie in Fig. 7, 8 und g der Zeichnung dargestellt. Man kann den Kabelkern jedoch auch gerade herstellen und mit Stützwänden oder dergleichen versehen, die verhindern, dafs er mit der Schutzhülle in Berührung kommt, um seine statische Capacität soviel als möglich zu verringern. _To surround telegraph cables with air as much as possible, and submarine cables, which have to withstand strong pressure to make the cable core very resistant arranged that it comes into as little contact as possible with its protective cover, and for this purpose it becomes the same instead of free in the. Protective cover to lie with off the central axis protruding points, for example in wave form, zigzag form and so on. brought in such a way that it can only touch the protective cover with its protruding points, as shown in Figs. 7, 8 and g of the drawing. However, you can also use the cable core just make and provided with supporting walls or the like that prevent him comes into contact with the protective cover in order to increase its static capacitance as much as possible to decrease. _
Ein Ausführungsbeispiel dieser Anordnung zeigt Fig. ι. Um den Hohldorn A wird ein Band B aus Papier oder anderem Isolirmittel von einer dem Umfange des Hohldorns entsprechenden Breite der Länge nach herumgelegt, so dafs die Ränder des Bandes auf dem Dorn zusammenstofsen. Auf das Band B werden sodann ein oder mehrere Bänder C schraubenförmig aufgewickelt, so dafs eine ringsum geschlossene Röhrenform entsteht. · Mit der gleichen Geschwindigkeit, wie die so gebildete Röhre über den Dorn vorbewegt wird, wird der Draht durch den Hohldorn vorbewegt, so dafs er von der Röhre völlig umschlossen wird. Das Band B bildet für das Band C einen Träger, wenn es von dem Dorn gezogen wird. Diese Bänder können nach Befinden mit nicht leitender Mischung getränkt werden.An embodiment of this arrangement is shown in FIG. Around the hollow mandrel A , a band B made of paper or other insulating material, with a width corresponding to the circumference of the hollow mandrel, is wrapped lengthways, so that the edges of the band collapse on the mandrel. One or more tapes C are then wound onto the tape B in a helical manner, so that a tubular shape that is closed all round is created. · At the same speed as the tube thus formed is advanced over the mandrel, the wire is advanced through the hollow mandrel so that it is completely enclosed by the tube. The tape B forms a support for the tape C as it is pulled from the mandrel. These tapes can be soaked with a non-conductive mixture after they are comfortable.
Zwei auf diese "Weise hergestellte Röhren mit eingeschlossenem Draht werden dann zusammengelegt und wie die Litzen eines Seiles an einander verdreht, so dafs die Querschnittsform Fig. 2 entsteht. Bei diesem Verdrehen legen sich Röhren und Drähte in eine Art Schraubenlinie, so zwar, dafs die Drähte möglichst nahe an einander, aber durch eine Isolirschicht völlig getrennt zu liegen kommen. Die Drähte können deshalb vor diesem Verdrehen auch gerade sein; durch das Zusammendrehen zweier Röhren gewinnen sie den erforderlichen Halt.Two tubes made in this way with enclosed wire are then put together and like the strands of a rope twisted in relation to one another, so that the cross-sectional shape of FIG. 2 arises. With this twisting if tubes and wires lay themselves in a kind of helical line, in such a way that the wires as much as possible close to each other, but completely separated by an insulating layer. the Wires can therefore also be straight before this twisting; by twisting it together two tubes give you the necessary support.
Derart zusammengedrehte Röhren werden nun durch zwei Ziehformen gezogen, wodurch nach einander die in Fig. 3 und 4 dargestellten Formen entstehen, und nun stellen die Röhren einen cylindrischen Körper mit einer Scheidewand von Isolirstoff dar, Fig. 4, welche die Hin- und Rückleitungsdrähte oder auch zwei Drähte gleicher Polarität trennt. Die Röhren können mittelst Ziehformen auch von anderem als rundem Querschnitt hergestellt werden.Tubes twisted together in this way are now pulled through two drawing molds, whereby the shapes shown in FIGS. 3 and 4 arise one after the other, and now the tubes a cylindrical body with a partition of insulating material, Fig. 4, which the There and return wires or two wires of the same polarity separates. The tubes can also be produced with other than round cross-sections by means of drawing forms.
Mehrere solcher isolirter Leiter können auf die in Fig. 5 dargestellte Weise vereinigt werden. Hierbei geht jede Kabelader durch Ziehformen, um sie angemessen zu gestalten und ein sehr festes Kabel zu erhalten. Die Kabeladern werden zweckmäfsig wie Litzen eines gewöhnlichen Seiles an einander verdreht. Ein solches zusammengesetztes Leitungskabel kann auf ge-Several such insulated conductors can be combined in the manner shown in FIG. Here, each cable core goes through draw molding to shape it appropriately and a very to get a solid cable. The cable cores are expediently like the strands of an ordinary one Twisted together. Such a composite line cable can be
wohnliche Weise von einer Bleiröhre umschlossen werden. Die Drähte können auch, statt rund, halbrund sein, besonders wenn zwei Drähte dieselbe Polarität besitzen und dadurch ein einziger Cylinder gebildet wird, welcher mit einer Papier- oder anderen Scheidewand zwischen den beiden Hälften versehen ist.comfortably enclosed by a lead pipe. The wires can also, instead of round, be semicircular, especially if two wires have the same polarity and thus a single cylinder is formed, which is provided with a paper or other partition between the two halves is.

Ein nach Anspruch 1. . hergestelltes elektrisches Kabel, das mit aus der Mittelachse heraustretenden Stellen, beispielsweise wellen- oder zickzackförmig hergestellt ist, so dafs es die Schutzhülle nur mit seinen vortretenden Stellen berühren kann.ι. Process for the manufacture of telegraph cables, consisting in inserting the wire or other conductor through a hollow mandrel (A) on which a band (B) of insulating material is placed lengthways in the form of a tube, and then around the band (B) one or more bands (C) of insulating material are wound helically, so that a tube with a larger inner diameter than the wire is obtained, whereupon two or more of the tubes thus produced with the enclosed wires are twisted together in the manner of rope strands, Fig. 2, and then go through drawing-forming, Fig. 3 and 4, until they assume the required shape, then assemble a series of bundles obtained in this way into a cylindrical shape and cover them with a protective cover, e.g. B. a lead pipe, Fig. 5.
A according to claim 1.. Manufactured electrical cable which is made with points protruding from the central axis, for example in a wave or zigzag shape, so that it can only touch the protective cover with its protruding points.
