Abstract

A multi-wire 1 flexible power line has integrated optical waveguides arranged as an optical waveguide cable 3 in one of the outer filling portions of the powder wires, the said cable 3 having a plastics shell 8 arranged around the twisted or loosely bunched optical waveguides 7, and a heat-insulating coating 9, and the energy fitting-portion chamber housing the optical waveguide cable 3 is filled with a filler 4 of jute threads or a similar material for protection against compression. The optical waveguide cable has a braiding 10 made of steel or plastics wires, which is stable under compression. Partial protective conductor wires 2, inner shell 5 and outer 6 are shown. <IMAGE>

Description

Die Erfindung betrifft eine mehradrige flexible Starkstrom­ leitung mit integrierten Lichtwellenleitern (LWL) nach dem Oberbegriff des Anspruchs 1.The invention relates to a multi-core flexible heavy current cable with integrated optical fibers (LWL) according to Preamble of claim 1.

Aus der DE 38 10 714 A1 ist eine mehradrige flexible Stark­ stromleitung, insbesondere Leitungstrosse, mit integrierten LWL bekannt, bei der die LWL als LWL-Ader in einem äußeren Zwickel der Energieadern angeordnet sind. Zum Zwecke des Schutzes der LWL ist über dem diese umgebenden Kunststoffmantel eine wärme­ dämmende Umhüllung aus mehreren Lagen von Gewebebändern und/ oder Vliesen aus einem bis mindestens 200°C wärmebeständigen Werkstoff von geringer Wärmeleitfähigkeit angeordnet, und der die LWL-Ader aufnehmende Energieaderzwickel ist zum mechanischen Schutz, insbesondere zum Druckschutz dieser LWL-Ader zu über 50% des Zwickelvolumens mit Trensen aus Jutefäden oder einem ähnli­ chen Material ausgefüllt.DE 38 10 714 A1 describes a multi-core flexible Stark Power line, in particular cable harness, with integrated FO known, in which the fiber as an optical fiber in an outer gusset the energy veins are arranged. For the purpose of protecting the LWL is a heat over the surrounding plastic sheath insulating covering made of several layers of fabric tapes and / or nonwovens made of a heat resistant up to at least 200 ° C Material of low thermal conductivity arranged, and the the fiber optic cable gusset is for mechanical Protection, especially for pressure protection of this fiber optic core to over 50% the gusset volume with bridles made of jute threads or similar Chen material filled.

Aus der DE 40 27 538 A1 ist ferner ein Energiekabel mit inte­ grierten LWL bekannt, bei dem eine im Zwickelbereich der Adern angeordnete LWL-Leitung mit einer Metallabdeckung als Feuchtig­ keits-Diffusionssperre versehen ist.From DE 40 27 538 A1 an energy cable with inte known fiber optic, one in the gusset area of the veins arranged fiber optic cable with a metal cover as moisture diffusion barrier is provided.

Bei der Herstellung einer derartigen mehradrigen flexiblen Starkstromleitung, bei der in einem der Energieaderzwickel eine LWL-Ader angeordnet ist, besteht die Gefahr, daß die bei der Vernetzung von Innenmantel und Außenmantel auftretenden hohen Drücke und Temperaturen sowie möglicherweise Zugbeanspruchungen die LWL-Ader schädigen. Auch beim Gebrauch unterliegen die Starkstromleitungen und damit die jeweils integrierte LWL-Ader hohen mechanischen Beanspruchungen, insbesondere beim Anschluß von ortsveränderlichen Großgeräten.In the manufacture of such a multi-core flexible Power line, in which one of the energy core gussets LWL core is arranged, there is a risk that the at  Networking of inner jacket and outer jacket occurring high Pressures and temperatures as well as possible tensile loads damage the fiber optic core. They are also subject to use Power lines and thus the integrated fiber optic wire high mechanical loads, especially when connecting of large, portable devices.

Der Erfindung liegt deshalb die Aufgabe zugrunde, die Tempera­ tur- und Druckbeständigkeit einer in einem Energieaderzwickel einer mehradrigen flexiblen Starkstromleitung angeordneten LWL- Ader zu erhöhen.The invention is therefore based on the object, the tempera Resistance to pressure and pressure in one gusset a multi-core flexible power cable Increase vein.

Die Aufgabe wird bei einer flexiblen Starkstromleitung nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnendes Merkmal gelöst.The task is with a flexible power line after the Preamble of claim 1 by its characteristic feature solved.

Die LWL-Ader wird mit einem formstabilen Geflecht oder einer Stützspirale aus Stahl- oder Kunststoffdrähten versehen, so daß Deformationen und Beschädigungen der LWL-Ader durch den bei der Herstellung der Starkstromleitung auftretenden Vernetzungsdruck vermieden werden. Überdies bewirkt diese Maßnahme einen mecha­ nischen Schutz für die LWL-Ader gegen Druck- und Quetschbean­ spruchungen beim Einsatz der Starkstromleitung.The fiber optic wire is with a dimensionally stable braid or Support spiral made of steel or plastic wires, so that Deformations and damage to the fiber optic core caused by the Establishment of the high-pressure line cross-linking pressure be avoided. In addition, this measure causes a mecha protection for the fiber optic core against pressure and crushing beans spells when using the power line.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels erläutert. Die zugehörige Zeichnung zeigt eine erfindungsgemäße Starkstromleitung im Schnitt.The invention is described below using an exemplary embodiment explained. The accompanying drawing shows an inventive Power line in section.

Die Starkstromleitung weist drei Energieadern 1, zwei Teil- Schutzleiteradern 2, eine LWL-Ader 3, Trensen 4 aus Jutefäden in dem die LWL-Ader 3 beherbergenden Energieaderzwickel, einen den Verseilverband umgebenden Innenmantel 5 und einen Außenmantel 6 auf. Die LWL-Ader 3 besteht aus einer Anzahl von kunststoffbe­ schichteten, lose gebündelten LWL 7, einem diese umgebenden Kunststoffmantel 8 aus PBT (Polyester), einer diesen umgebenden wärmedämmenden Umhüllung 9 aus Gewebeband und einem darüber an­ geordneten Geflecht 10 mit hoher Oberflächenbedeckung und Knickfestigkeit aus (2 × 8 × 1) × 0,31 mm verzinkten Stahlrund­ drähten nach DIN 2078 mit einer Nennfestigkeit von 1770 N/qmm und einer Steigung von 45°.The power line has three energy cores 1 , two partial protective conductor cores 2 , an optical fiber core 3 , bridles 4 made of jute threads in the energy core gusset accommodating the fiber optic core 3 , an inner jacket 5 surrounding the stranding assembly and an outer jacket 6 . The fiber optic core 3 consists of a number of plastic-coated, loosely bundled fiber-optic cables 7 , a plastic sheath 8 made of PBT (polyester) surrounding them, a heat-insulating sheath 9 made of fabric tape surrounding them, and an above-ordered braid 10 with high surface coverage and kink resistance (2 × 8 × 1) × 0.31 mm galvanized steel wire according to DIN 2078 with a nominal strength of 1770 N / qmm and a pitch of 45 °.
