Derartige flexible elektrische Starkstromleitungen werden beispielsweise als sogenannte Schleppkettenleitungen zur Energieversorgung von ortsveränderlichen Verbrauchern eingesetzt. In vielen Fällen ist zusätzlich die Übertragung von Steuer- oder Meßsignalen und Nachrichten erforderlich. Zu diesem Zweck werden in den bekannten Schleppketten zusätzliche Steuer- oder Meßleitungen sowie gegebenenfalls Nachrichtenübertragungsleitungen angeordnet. Dabei ist es notwendig, die vergleichsweise dünnen Steuer- oder Meßleitungen sowie Nachrichtenübertragungsleitungen gut vor unzulässig hohen mechanischen Beanspruchungen zu schützen. Eine derartig aufgebaute, Leitungen für die verschiedensten Zwecke aufweisende Schleppkette ist vergleichsweise aufwendig und teuer und weist große Abmessungen auf.Such flexible electrical power lines are for example as so-called drag chain cables Energy supply for portable consumers used. In many cases this is additionally Transmission of control or measurement signals and messages required. For this purpose, in the known Drag chains additional control or measuring lines as well where appropriate, communication lines arranged. It is necessary to do this comparatively thin control or measuring lines as well Communication lines well in front of impermissibly high to protect mechanical loads. One of those assembled, lines for various purposes having a drag chain is comparatively complex and expensive and has large dimensions.

Im Bergbau werden trommelbare elektrische Starkstromleitungen verwendet, bei denen in den Außenzwickeln zwischen den Energieadern Steueradern oder Nachrichtenübertragungsadern angeordnet sind.

Ausgehend von diesem Stand der Technik liegt der Erfindung das Problem zugrunde, eine flexible elektrische Starkstromleitung auszubilden, in der eine ausreichend große Anzahl von elektrischen Steuerleitern zur Übertragung von Steuersignalen auf einfache Art und Weise und vor mechanischen Beanspruchungen gut geschützt integriert ist.Based on this state of the art Invention based on the problem of a flexible electrical Train power line in which a sufficient large number of electrical control conductors Transmission of control signals in a simple way and well protected against mechanical stress is integrated.

Bei der Verwendung der erfindungsgemäßen hybriden Starkstromleitung beispielsweise als in einer flexiblen Schleppkette angeordnete Schleppkettenleitung ist es nicht erforderlich, zusätzlich parallel zu der Starkstromleitung verlaufende Steuerleitungen vorzusehen, da die Starkstromleitung die Funktionen der Energieübertragung sowie der Übertragung von Steuersignalen vereint. Die Schleppkette kann daher vergleichsweise geringe äußere Abmessungen aufweisen, was in vielen Anwendungsfällen von Vorteil ist. Die erfindungsgemäße flexible elektrische Starkstromleitung ist zudem einfach und kostengünstig herstellbar.The advantages that can be achieved with the invention exist especially in that a large number of isolated electrical control conductors in a simple manner integrated into the flexible electrical power line can be. The central control wire with the one in it arranged control ladder is due to its central Position in the cable structure well in front of impermissibly high mechanical Protected against stress. When using the Hybrid power line according to the invention for example as in a flexible drag chain arranged drag chain cable is not required, in addition to parallel to the To provide power lines running control lines, since the power line performs the functions of Energy transfer as well as the transfer of Control signals united.
