Derartige Starkstromleitungen werden beispielsweise zur Energieversorgung ortsveränderlicher Verbraucher eingesetzt, die auf vorgegebenen Wegen hin- und herbewegt werden. Solche Verbraucher sind beispielsweise Motoren von Transportwagen, Werkzeugschlitten oder Kränen. Die Starkstromleitungen sind auch dann einsetzbar, wenn ein leicht herstellbarer, flexibler Anschluß von Verbrauchern an eine Spannungsquelle benötigt wird, der ebenso leicht wieder abbaubar sein soll. Ein spezieller Anwendungsfall ist hier die Stromversorgung von in Warteposition befindlichen Flugzeugen, die bei abgeschalteten Triebwerken vom Rollfeld aus mit Energie versorgt werden. Die in den Starkstromleitungen enthaltene Steuerleitung kann zur Übertragung von Steuersignalen eingesetzt werden, durch welche den entsprechenden Geräten eingeprägte Funktionen aktiviert werden können.Such power lines are used, for example, for energy supply portable consumers are used, who go back and forth in predetermined ways be moved. Such consumers are, for example, motors from Transport trolleys, tool slides or cranes. The power lines are too can be used when an easily manufactured, flexible connection to consumers a voltage source is required, which should also be easy to dismantle. On A special application is the power supply of those in the waiting position Aircraft that supply energy from the tarmac when the engines are switched off become. The control line contained in the power lines can be used for transmission of control signals are used by which the corresponding devices embossed functions can be activated.

Bei der bekannten Starkstromleitung nach der eingangs erwähnten DE-U-296 13 870 ist die aus mehreren elektrisch isolierten Leitern bestehende Steuerleitung im Kern angeordnet. Dadurch kann eine Steuerleitung mit einer größeren Anzahl von Leitern mechanisch gut geschützt im Querschnitt der Starkstromleitung untergebracht werden. Zur elektrischen Abschirmung kann die Steuerleitung von einem Geflecht aus Kupferdrähten umgeben sein. Über dessen Aufbau sind ebenso keine Angaben gemacht, wie über das die Energieadern als Abschirmung umgebende Geflecht.In the known power line according to the aforementioned DE-U-296 13 870 the core of the control line consisting of several electrically insulated conductors arranged. This allows a control line with a larger number of conductors mechanically well protected in the cross section of the power line. For electrical shielding, the control line can be made from a braid Be surrounded by copper wires. There is also no information about its structure made as about the braid surrounding the energy veins as a shield.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Starkstromleitung unter Beibehaltung ihrer guten Flexibilität so zu gestalten, daß sie auch bei höheren Frequenzen nicht stört.The invention has for its object the power line described above while maintaining their good flexibility so that they can be used even at higher levels Frequencies does not bother.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß zusätzlich mindestens eine Datenleitung vorgesehen ist, die von einem als Abschirmung dienenden Geflecht aus metallischen Drähten mit einer optischen Bedeckung von mindestens 85 % umgeben ist, das einen flachen, zwischen 50° und 60° liegenden Steigungswinkel hat,
  • daß das Geflecht der Abschirmung der Energieadern eine optische Bedeckung von mindestens 80 % hat und mit einem flachen, zwischen 50° und 60° liegenden Steigungswinkel aufgebracht ist und
  • daß der Kern ein zentrales Zugelement aufweist, über dem eine Umhüllung aus einem vernetzbaren Material angebracht ist, welche für jede herumverseilte Energieader eine der Kontur derselben angepaßte, sich über die ganze axiale Länge des Kerns erstreckende Eindellung hat.
According to the invention, this object is achieved by
  • that at least one data line is additionally provided, which is surrounded by a braid of metallic wires serving as a shield with an optical coverage of at least 85%, which has a flat pitch angle between 50 ° and 60 °,
  • that the braid of the shielding of the energy veins has an optical coverage of at least 80% and is applied with a flat, between 50 ° and 60 ° slope angle and
  • that the core has a central tensile element, over which a covering made of a cross-linkable material is attached, which has an indentation adapted to the contour thereof for each stranded energy vein and extending over the entire axial length of the core.

Mit dieser Starkstromleitung können neben Energie und Steuerbefehlen zusätzlich auch Daten übertragen werden, beispielsweise Meßdaten. Die dafür vorgesehene Datenleitung ist von einem Geflecht mit sehr hoher optischer Bedeckung umgeben, so daß eine Störung der Datenübertragung durch hochfrequente Felder oder Energie weitestgehend ausgeschlossen werden kann. Das gilt insbesondere für hochfrequente Ströme mit einer Frequenz von beispielsweise 400 Hz, die über die in der gleichen Starkstromleitung angeordneten Energieadern übertragen werden. Bei Verwendung höherer Frequenzen in der Größenordnung der erwähnten 400 Hz läßt sich beispielsweise das Drehmoment von an die Starkstromleitung angeschlossenen elektrischen Motoren besser steuern. Hinzu kommt, daß die Energieadern selbst von einem Geflecht mit einer sehr hohen optischen Bedeckung umgeben sind, so daß auch eine von denselben ausgehende Störstrahlung weitestgehend ausgeschlossen werden kann. Trotz der elektrisch dichten Geflechte der Abschirmungen bleibt die Starkstromleitung insgesamt gut flexibel und auf Dauer biegefest, da beide Geflechte mit flachem Steigungswinkel ausgeführt sind. Die gute Biegbarkeit der Starkstromleitung wird durch die spezielle Ausbildung des Kerns unterstützt, in dessen dem jeweiligen herumverseilten Element angepaßte Eindellungen diese Verseilelemente beim Biegen der Starkstromleitung gleiten können. Die Starkstromleitung ist darüberhinaus durch das Zugelement des Kerns auch bei größeren Zugbelastungen geschützt.In addition to energy and control commands, this power line can also be used Data are transmitted, for example measurement data. The intended one Data line is surrounded by a braid with a very high optical coverage, so that interference with data transmission due to radio frequency fields or energy can be largely excluded. This applies in particular to high-frequency Currents with a frequency of 400 Hz, for example, that in the same Power lines arranged energy wires are transmitted. Using higher frequencies in the order of 400 Hz mentioned can be for example the torque of connected to the power line better control electric motors. In addition, the energy veins themselves from are surrounded by a mesh with a very high optical coverage, so that too interference radiation emanating from the same can be largely excluded can. Despite the electrically dense braids of the shields, it remains Power line overall well flexible and permanently resistant to bending, since both braids with flat pitch angle are executed. The good flexibility of the power line is supported by the special training of the core, in which the respective Adjusted dents around stranded element these stranding elements when bending the Power line can slide. The power line is also through that Tension element of the core protected even with larger tensile loads.

Die entsprechende Energieader 1 ist dadurch gut flexibel und auch bei Frequenzen in der Größenordnung von 400 Hz elektrisch nahezu dicht. In bevorzugter Ausführungsform liegt der Steigungswinkel des Geflechts 11 bei 53°. Das ergibt eine optische Bedeckung von 85 %.The braid 11 has a flat pitch angle that lies between 50 ° and 60 °, molded around the insulated conductor 9.
