Description

Bekanntlich kann man durch die Wahl sektorförmiger Leiter den Außendurchmesser von Mehrleiter-Starkstromkabeln beträchtlich verringern. Die gebräuchlichen dehnbaren Starkstromkabel haben überwiegend runde Leiter, weil bisher nur runde Leiter in dehnbarer Ausführung bekannt sind. Es ist zwar auch vorgeschlagen worden, aus Sektorleitern dehnbare Starkstromkabel aufzubauen. Dabei sind aber die einzelnen isolierten Leiter voneinander durch im Kabelquerschnitt exzentrisch angeordnete nachgiebige Einlagen getrennt, und diese Einlagen vergrößern wieder den Kabeldurchmesser, 'so daß die durch die S3ktorform ermöglichte Verkleinerung des Kabeldurchmessers verlorengeht.As is well known, you can choose the outer diameter by choosing sector-shaped conductors of multi-conductor power cables considerably. The common stretchable Power cables mainly have round conductors, because so far only round conductors have been used stretchable execution are known. Although it has also been suggested, from sector leaders to build stretchable power cables. However, the individual conductors are insulated from each other by resilient inserts arranged eccentrically in the cable cross-section separated, and these deposits increase the cable diameter again, 'so that the The reduction in cable diameter made possible by the gate shape is lost.

Nach der Erfindung ist jeder einzelne sektorförmige Leiter des Kabels in sich dehnbar. Dadurch ist auch für dehnbare Mehrleiter-Starkstromkabel eine beträchtliche Verringerung des Außendurchmessers gegenüber einem Kabel mit runden Leitern möglich, und das Kabel wird leichter und billiger.According to the invention, each individual sector-shaped conductor of the cable is elastic in itself. This is a considerable amount even for stretchable multi-conductor power cables Reduction of the outer diameter possible compared to a cable with round conductors, and the cable becomes lighter and cheaper.

Vorzugsweise besitzt der sektorförmige Leiter einen ausschließlich aus gewundenen Drähten aufgebauten sektorförmigen Kern. Die Drähte des Kernes können zum Teil oder sämtlich wellenförmig oder schraubenförmig gewunden sein. Der Kern kann aber auch sowohl wellenförmig gewundene wie schraubenförmig gewundene Drähte enthalten. Über einem Kern der beschriebenen Art können eine oder mehrere verseilte Lagen aus Drähten in an sich bekannter Weise angeordnet sein.Preferably, the sector-shaped conductor has one exclusive Sector-shaped core made up of twisted wires. The wires of the core can be partly or entirely wavy or helical. The core but it can also be both wave-shaped and helically wound wires contain. Over a core of the type described, one or more stranded Layers of wires can be arranged in a manner known per se.

Die Zeichnung zeigt beispielsweise in Fig. i ein Dreileiter-Starkstromkabel nach der Erfindung im Querschnitt. Die Fig. 2 stellt einen Leiter des Kabels gemäß Fig. i in einer Ansicht dar. Die Fig. 3 bis 6 zeigen zwei weitere Ausführungsformen des Sektorleiters für ein Kabel nach der Erfindung teils in Ansicht, teils im Querschnitt. In den Ansichten der Fig. 2, 3 und 5 sind jeweils die einzelnen Schichten des Leiters stufenweise abgesetzt, damit der Aufbau besser erkennbar wird.The drawing shows, for example, a three-wire power cable in FIG according to the invention in cross section. Fig. 2 shows a conductor of the cable according to Fig. I in a view. Figs. 3 to 6 show two further embodiments of the sector conductor for a cable according to the invention partly in view, partly in cross section. In the views of FIGS. 2, 3 and 5, the individual layers of the conductor are in each case Gradually removed so that the structure is easier to see.

In Fig. i bezeichnen i die sektorförmigen Leiter des Kabels, 2 die Leiterisolierungen und 3 den Kabelmantel. Der sektorförmige Kern des Leiters i ist nach den Fig. i und 2 aus den Drähten 4 aufgebaut, die sämtlich wellenförmig gewunden sind. Gemäß den Fig. 3 und 4 besteht der Kern des Leiters aus lauter schraubenförmig gewundenen Drähten 5. In den Fig. 5 und 6 schließlich ist eine Ausführungsform dargestellt, bei der der Kern des Leiters aus Drahtlitzen 6 und 7 gebildet ist, die wiederum über schraubenförmig gewundenen Kerndrähten 8 und g verseilt sind. Die über dem sektorförmigen Kern verseilte Drahtlage ist jeweils mit io bezeichnet.In Fig. I, i denote the sector-shaped conductors of the cable, 2 denote the Conductor insulation and 3 the cable sheath. The sector-shaped core of the conductor i is built up according to FIGS. i and 2 from the wires 4, all of which are wound in an undulating manner are. According to FIGS. 3 and 4, the core of the conductor consists of nothing but helical shapes coiled wires 5. Finally, FIGS. 5 and 6 show an embodiment, in which the core of the conductor is formed from wire strands 6 and 7, which in turn are stranded over helically wound core wires 8 and g. The one above that A wire layer stranded in a sector-shaped core is denoted by io.
