Description

Mehrleiterkabel Irr, Hauptpatent . ... ... (Patentanmeldung S 103 666 IITIII d/21 h vom 6. 5. 1966) wird ein Mehrleiterkabel beschrieben, dessen Leiter vorwiegend aus Aluminium bestehen, mit zentral angeordnetem Nulleiter und darüber verseilten Hauptleitern, die einzeln und gemeinsam mit Kunststoff isoliert sind.Multi-conductor cable Irr, main patent. ... ... (patent application p. 103 666 IITIII d / 21 h of May 6, 1966) describes a multi-conductor cable whose conductor consist mainly of aluminum, with a centrally arranged neutral conductor and above stranded main conductors that are individually and collectively insulated with plastic.

Neben den Vorteilen der im Hauptpatent beschriebenen Anordnung haftet ihr der Nachteil an, daß bei Beschädigung des Kunststoffmantels durch Werkzeuge, die beteiligten Personen gefährdet sind. Das Hauptpatent beschreibt zur Beseitigung dieses Nachteils ein Mehrleiterkabel, dessen Leiter vorwiegend aus Aluminium bestehen mit zentral angeordnetem Nulleiter und darüber verseilten Hauptleitern, die einzeln und gegebenenfalls gemeinsam mit Kunststoff isoliert sind, wobei zwischen Seele und Mantel eine elektrisch leitende Bewehrung angeordnet ist, deren Querschnitt einem elektrischen Leitwert von mindestens 6 mm 2 Kupfer entspricht. Ein etwa in das Kabel durch dessen Kunststoffmantel eindringendes Werkstück wird an dieser Bewehrung sofort geerdet, so daß der eingangs geschilderte Nachteil behoben ist.In addition to the advantages of the arrangement described in the main patent, adheres her disadvantage is that if the plastic jacket is damaged by tools, the people involved are at risk. The main patent describes the elimination this disadvantage is a multi-conductor cable whose conductors consist predominantly of aluminum with a centrally arranged neutral conductor and main conductors stranded above them, which are individually and are optionally insulated together with plastic, with between the soul and jacket an electrically conductive reinforcement is arranged, the cross section of which corresponds to an electrical conductivity of at least 6 mm 2 copper. A roughly in the cable through its plastic sheath penetrating workpiece is attached to this reinforcement immediately grounded, so that the disadvantage described at the beginning is eliminated.

Nun wird aber im allgemeinen großer Wert auf eine Flächenerdung gelegt. Diese ist aber bei Kabeln mit Bleimantel gegeben, da die über dem Bleimantel befindliche Bitumenschicht wasserdurchlässig ist. Kabel mit Aluminiummantel, die mit einer Kunststoffschicht überzogen sind,-damit Korrosion vermieden wird, weisen eine solche Flächenerdung nicht auf. Der Aluminiummantel wiederum darf nicht als Nulleiter geschaltet werden, so daß nur die zentrische Anordnung des Nulleiters aus Aluminium verbleibt.In general, however, great importance is attached to surface earthing. However, this is the case with cables with lead sheath, since the one above the lead sheath Bitumen layer is permeable to water. Cable with aluminum jacket covered with a plastic layer are covered with it Corrosion is avoided, exhibit such a Surface grounding does not apply. The aluminum jacket, on the other hand, must not be switched as a neutral conductor so that only the central arrangement of the neutral conductor made of aluminum remains.

Zur Erzielung einer guten Flächenerdung schlägt deshalb die Erfindung ein Mehrleiterkabel vor, mit zentrisch angeordnetem Nulleiter, darüber verseilten Hauptleitern und einer zwischen Seele und Mantel angeordneten elektrisch leitenden Bewehrung aus Kupfer und/oder verzinkten oder verbleiten Stahldrähte, deren Querschnitt einem elektrischen Leitwert von mindestens 6 mm 2 Kupfer entspricht, wobei der über der Bewehrung angeordnete Mantel aus halb- oder schwachleitendem Kunststoff besteht.The invention therefore proposes to achieve good surface earthing a multi-conductor cable in front, with a centrally arranged neutral conductor, stranded over it Main conductors and an electrically conductive one arranged between the core and the jacket Reinforcement made of copper and / or galvanized or leaded steel wires, their cross-section corresponds to an electrical conductance of at least 6 mm 2 copper, with the above the reinforcement arranged jacket consists of semi-conductive or weakly conductive plastic.

Nach dem weiteren Merkmal der Erfindung soll dieser Mantel aus halb- oder schwachleitendem-Kunststoff feuchtigkeitsaufsaugend sein.According to the further feature of the invention, this jacket should be made of half- or low-conductivity plastic that absorbs moisture.

In den Abbildungen ist die Erfindung zeichnerisch erläutert. Die Figuren 1 und 2 zeigen Schnitte durch Mehrleiterkabel mit dem erfindungsgemäßen Kunststoffmantel.The invention is illustrated graphically in the figures. The figures 1 and 2 show sections through multi-conductor cables with the plastic sheath according to the invention.

Der zentrale Nulleiter aus Aluminium trägt das Bezugszeichen 1. Rings um den Nulleiter 1 sind isolierte Hauptleiter 2 angeordnet, die von einer Schutzhülle 3 aus Kunststoff eingeschlossen sind. Über der Schutzhülle 3 befindet sich die erfindungsgemäße Bewehrung 4, die indem gezeichneten Beispiel aus Stahl-Flachdrähten besteht. Wie die Figur 2 erkennen läßt, können zwischen den einzelnen Drähten der Bewehrung 4 Lücken vorhanden sein, die mit trensenartigen Strängen 5 ausgefüllt sind. Der äußere Kunststoffmantel aus halb- oder schwachleitendem Kunststoff ist mit dem Bezugszeichen 6 gekennzeichnet. Für diesen Kunststoffmantel können beispielsweise Polyvenyl-Chlorid, Polyäthylen, Polypropylen, allgemeine Polyolefine verwendet werden. Diese Kunststoffe werden beispielsweise durch Graphit oder Metallzusätze leitend gemacht.The central neutral conductor made of aluminum bears the reference number 1. Ring around the neutral conductor 1 insulated main conductors 2 are arranged, which are covered by a protective sheath 3 made of plastic are included. Above the protective cover 3 is the inventive Reinforcement 4, which in the example shown consists of flat steel wires. As As can be seen in FIG. 2, between the individual wires of the reinforcement 4 There may be gaps that are filled with snaffle-like strands 5. The outer one Plastic jacket made of semi-conductive or weakly conductive plastic is denoted by the reference symbol 6 marked. For this plastic sheath can for example Polyvinyl chloride, polyethylene, polypropylene, general polyolefins can be used. These plastics become conductive, for example through graphite or metal additives made.
