An improvement in the manufacture of insulated high-voltage electrical cables with paper envelopes impregnated with insulating oils or with insulating mixtures based on oils coated with a generally metal impermeable layer (for example lead) and possibly also subjected to gaseous or oleo-static pressure which consists essentially in the fact that the rope or the conductor cords of the cable are wrapped in direct contact by one or more strips of electrically conductive non-metallic fabric.
