Die Erfindung betrifft ein einphasiges gekühltes kunststoffummanteltes Starkstromkabel, dessen Leiter aus einer Vielzahl· einzelner Leitungsdrähte besteht. .The invention relates to a single-phase, cooled, plastic-sheathed power cable, the conductors of which are made up of a multitude of individual lead wires. .
Es ist bekannt, daß ein Strom, wenn er durch einen elektrischen Leiter fließt, diesen erwärmt. Nun ist es häufig wünschenswert, insbesondere, wenn es sich bei dem Leiter um ein Starkstromkabel handelt, das in einem Raum verlegt ist, in dem eine möglichst konstante Temperatur herrschen soll, daß die entstandene Stromwärme nicht an die das Kabel umgebende Atmosphäre abgegeben wird, sondern auf andere Weise fortgeleitet wird. Dies gilt insbesondere dann, wenn in dem Raum in dem das Kabel verlegt ist, Apparaturen stehen, die genau justiert sein müssen und deren Justierung durch Temperaturschwankungen zunichte gemacht werden. Die Temperatur am Außenmantel des Kabels darf JO C nicht überschreiten, wenn keine Raumerwärmung auftreten soll. Man hat zu diesem Zweck die Kabel mit isolierenden Schichten umhüllt, jedoch ist diese Methode recht aufwendig und häufig fehlt der Raum, den diese zusätzliche Wärmeisolierung einnimmt. It is known that a current, when flowing through an electrical conductor, heats it. Now it is often desirable, especially when the conductor is a power cable that is laid in a room in which the temperature should be as constant as possible, that the resulting heat from the current is not given off to the atmosphere surrounding the cable, but is forwarded in another way. This is especially true if there are apparatuses in the room in which the cable is laid which must be precisely adjusted and whose adjustment is nullified by temperature fluctuations. The temperature on the outer sheath of the cable must not exceed JO C if the room is not to be warmed up. For this purpose, the cables have been sheathed with insulating layers, but this method is quite complex and often the space that this additional thermal insulation takes up is missing.
Der Erfindung liegt die Aufgabe zugrunde, ein geeignetes Kabel für obengenannte Zwecke zn schaffen, das die Nach-The invention is based on the object create zn for the above purposes, a suitable cable that demand the

teile der beschriebenen Kabel nicht mehr aufweist. Gemäß der Erfindung sind die einzelnen Leitungsdrähte um ein Metallrohr herumverseilt, daß zur Fortleitung eines Kühlmediums dient. Ein solches Kabel ist nur unwesentlich dicker als ein normales ungekühltes Kabel und die Temperatur am Außenmantel des Kabels liegt unter 3O°C, sodaß eine störende Raumerwärmung nicht auftritt. Damit das Rohr möglichst korrosionsbeständig ist, verwendet man verteilhaft ein Rohr aus Kupfer* Den Zwischenraum zwischen dem Metallrohr und den einzelnen Leitungsdrähten füllt man zweckmäßig mit einer wärmel ext fälligen Paste aus, die auf dem Markt erhältlich ist. Hierdurch wird der Wärmeübergang von den Leitungsdrähten zum Kühlmedium wesentlich verbessert. Mit Vorteil faßt man die einzelnen Leitungsdrähte noch zu einzelnen Profilleitern zusaoaen, die dann um das Metallrohr herumverseilt werden·no longer has parts of the cables described. According to the invention, the individual lead wires are around a Metal tube stranded around that for conveying a cooling medium serves. Such a cable is only slightly thicker than a normal uncooled cable and the temperature on the outer sheath of the cable is below 30 ° C, so that a disruptive heating of the room does not occur. So that Pipe is as corrosion-resistant as possible, a pipe made of copper is used to distribute the space between the metal tube and the individual lead wires are expediently filled with a paste which is due to warm ext is available in the market. This significantly improves the heat transfer from the lead wires to the cooling medium. It is advantageous to combine the individual line wires to form individual profile conductors, which then surround the Metal pipe are stranded around
Weitere Vorteile der Erfindung sind aus der nachfolgenden Beschreibung zweier in den Figuren 1 und 2 dargestellten Ausführungsbeispiele ν zu ersehen.Further advantages of the invention are evident from the following Description of two embodiments shown in Figures 1 and 2 ν can be seen.
