ABSTRACT OF THE DISCLOSURE: A process for making a multi-core, fluid impregnated electric, submarine cable of long length in which each core is separately formed, impregnated and sheathed before the so-formed units are combined within an arms layer which is covered by a bituminous material. Each unit is formed by forming a conductor of long length having an oil conduit therein. The conductor is covered by paper tape insulation layers, conductive screening layers optionally being applied be- fore and after the covering of the conductor by the paper tape. The so-formed core is then vacuum treated and impregnated with insulating oil, covered with a fluid impermeable sheath Which is then protected by blindage of metal tape. Over the blindage, a plastics sheath is formed, and the so-formed unit is combined with similar units which are covered by the armor layer of metal and the layer of bituminous material. The spaces between units and between the units and the armor layer may be filled with a filler material. Also, a cable produced by such process.
