Abstract of the Disclosure Disclosed is a screened electric cable resistant to tension and having a non-metallic load-relieving means made of glass fibres in which the satisfactory mechanical and electrical properties associated with unscreened designs are retained. The cable comprises one or more insulated conductors as the cable core and insulating foil wound thereover. A plastic internal sheath is extruded around the cable core and covered with an electrostatic shield of metal foil which, in turn, is surrounded by a plastic external sheath in which are embedded bundles of glass fibres arranged concentrically with the cable core, running parallel therewith, and spaced apart from each other. A ratio of about 1:3:1 is provided between the wall thickness of the insulating sheath of the conductors, the wall thickness of the internal sheath, and the distance between the screen and the glass fibre bundles.
