Description
Leitung mit einer Isolation aus Gummi und einer aus Stahl- und Kupferdrähten gebildeten Bewehrung Es ist bekannt, bei Leitungen ohne Bleimantel, insbesondere bei gummi- oder kunststoffisolierten Leitungen, außen bzw. unter einem Außenmantel ein Geflecht oder eine dicht gewickelte Wendel aus Stahldrähten oder -litzen vorzusehen. Diese Bedeckung dient vorwiegend dem mechanischen Schutz, wird aber häufig zugleich als elektrisch leitender Schirm verwendet. Da für den letzteren Zweck in der Regel die Leitfähigkeit der Stahldrähte nicht ausreicht, wurden einzelne Stahldrähte oder -litzen durch Kupfer ersetzt.Cable with an insulation made of rubber and one made of steel and copper wires It is known for lines without a lead jacket, in particular with rubber or plastic insulated cables, outside or under an outer jacket to provide a braid or a tightly wound coil made of steel wires or strands. This cover is mainly used for mechanical protection, but is often used at the same time used as an electrically conductive screen. As for the latter purpose, as a rule The conductivity of the steel wires is insufficient, were individual steel wires or - strands replaced by copper.
Da die Kupferleiter gegenüber mechanischen Einflüssen wesentlich weniger widerstandsfähig sind als die Stahldrähte, sind sie den an eine solche Bewehrung gestellten mechanischen Beanspruchungen jedoch häufig nicht gewachsen. Sie zerreißen leicht bei Schlagbeanspruchungen oder durch Abrieb, und die heraustretenden Enden können zu Verletzungen führen oder den Gummi nach innen durchbohren und Erdschluß hervorrufen. Diese Nachteile werden bei einer Leitung mit einer Isolation aus Gummi oder gummiartigem Stoff und mit einer aus Stahl- und Kupferdrähten gebildeten Bewehrung, welche die Leitung konzentrisch umgibt, dadurch vermieden, daß gemäß der Erfindung die einzelnen Bewehrungsstränge in an sich bekannter Weise aus Litzen bestehen, die jedoch in nur für Hauptleiter bekannter Weise aus einem Kupferleiter im Kern und um diesen verseilten Stahldrähten gebildet sind.Because the copper conductors are much less exposed to mechanical influences are more resistant than the steel wires, they are the ones attached to such a reinforcement However, the mechanical stresses posed are often not able to cope with them. They tear up easy in the event of impact or abrasion, and the protruding ends can lead to injuries or pierce the rubber inwards and earth fault cause. These disadvantages arise in the case of a line with insulation made of rubber or rubber-like material and with a reinforcement formed from steel and copper wires, which concentrically surrounds the line, thereby avoided that according to the invention the individual reinforcement strands consist of strands in a manner known per se, which, however, in a manner known only for main conductors, consists of a copper conductor in the core and around these stranded steel wires are formed.
Durch diese Maßnahme ist der Kupferdraht stets vor mechanischen Beanspruchungen gut geschützt und kann, selbst wenn er reißen sollte, nicht nach außen heraustreten.This measure means that the copper wire is always protected from mechanical stress well protected and, even if it should tear, cannot escape to the outside.
Zwar sind bereits Leitungen bekannt, deren Hauptleiter aus einem Kupferleiter besteht, der zur Erhöhung der Zugfestigkeit mit einer Lage aus Stahldrähten umgeben ist. Bei diesem Aufbau ist aber nicht zu erwarten, daß die Kupferdrähte eher zerreißen als die Stahldrähte, und die Stahldrähte sind nicht als mechanischer Schutz und Abdeckung für die Kupferleiter gegenüber Schlageinwirkung oder Abtrieb gedacht. F i g. 1 zeigt einen Leiter mit einem zentralen Kupferdraht 1 und sechs herumgelegten Stahldrähten 2.Lines are already known whose main conductor consists of a copper conductor which is surrounded by a layer of steel wires to increase the tensile strength is. With this structure, however, it is not to be expected that the copper wires will tear than the steel wires, and the steel wires are not used as mechanical protection and Cover for the copper conductor intended to protect against impact or downforce. F i g. Figure 1 shows a conductor with a central copper wire 1 and six wrapped around it Steel wires 2.
F i g. 2 stellt die Ansicht einer Leitung mit abgesetztem Ende dar, bei der Leiter gemäß F i g. 1 als Geflecht 3 verwendet sind.F i g. 2 shows the view of a pipe with a remote end, at the ladder according to FIG. 1 are used as braid 3.
