Abstract: A sheath is disclosed which provides protection against radiation. The sheath surrounds or is configured to surround at least a neutral cable, a earth cable and a phase cable which are all connected to the power grid. The sheath includes an outer layer made from electrically insulating plastic which covers an inner layer made from electrically conductive material, elements being provided to connect the layer of electrically conductive material to an electrical conductor intended to be earthed. The conductor to be earthed takes the form of a wire, all or part of which is made from electrically conductive material that extends internally along the entire length of the sheath and which is in electrical contact, at least along part of the length thereof, with the inner layer of electrically conductive material.

Abstract: A protective sheath against radiation, in particular derived from electric field generated by electric cables (1, 2, 3) extending inside the sheath. The sheath includes an electrically insulating plastic outer layer (4) covering an electrically conductive material layer (5), the sheath end including removable connecting elements for connecting the electrically conductive material layer (5) to an electrical conductor (7) designed to be connected to the ground, the sheath enclosing or designed to enclose at least one neutral cable (1), one ground cable (2) and one phase cable (3) connected to an electric power distribution system.

Abstract: The invention concerns a protective sheath against radiation, in particular derived from electric field generated by electric cables (1, 2, 3) extending inside the sheath. The invention is characterized in that it comprises an electrically insulating plastic outer layer (4) covering an electrically conductive material layer (5), the sheath end including removable connecting means for connecting the electrically conductive material layer (5) to an electrical conductor (7) designed to be connected to the ground, said sheath enclosing or designed to enclose at least one neutral cable (1), one ground cable (2) and one phase cable (3) connected to an electric power distribution system.
