Abstract
This patent application relates to a coaxial cable as well as to the manufacture of such a cable. Said cable comprises a central conductor and an outer conductor which are separated from each other by an electrically insulating layer, said outer conductor being provided, if necessary, with at least a protective coating. In accordance with the invention, the outer conductor of the cable comprises an electroconductive lacquer layer. In accordance with a preferred embodiment, a metal layer is applied to said lacquer layer. The cables in accordance with the invention can be manufactured much more rapidly than the known cables which comprise a stranded outer conductor or an outer conductor of metal foil. This advantage occurs in particular in the manufacture of very thin coaxial cables. In addition, the cables in accordance with the invention exhibit a satisfactory electromagnetic shielding.
