Abstract

Es wird ein Verfahren zur Herstellung eines Koaxialkabels beschrieben, bei welchem auf einen kontinuierlich zugeführten Innenleiter eine dielektrische Schicht aufextrudiert wird, um diesen so gebildeten isolierten Leiter ein längseinlaufendes Metallband zum Schlitzrohr geformt und an seinen Längskanten verschweißt wird, und das geschweißte Rohr auf die Oberfläche der dielektrischen Schicht heruntergezogen wird. Hierbei wird ein zumindest auf einer seiner Oberflächen mit einer Kunststoffschicht versehenes Metallband verwendet, und das Verschweißen der Längskanten wird durch Laserschweißen vorgenommen. A method for producing a coaxial cable is described, in which a dielectric layer is extruded onto a continuously supplied inner conductor, around which insulated conductor thus formed a longitudinally running metal strip is formed into a slot tube and welded on its longitudinal edges, and the welded tube onto the surface of the dielectric layer is pulled down. In this case, a metal strip provided with a plastic layer on at least one of its surfaces is used, and the longitudinal edges are welded by laser welding.
