Abstract

Around an insulating central core (1) is arranged a first conductive component planned to put to earth a lightning installation. This first conductive component is composed of metallic wires (2) spreading parallel to the axis (3) of the whole. An annular coating made of insulating material (4) is arranged around the metallic wires (2) and a second conductive component, constituted by metallic wires (5), is arranged around this intermediate insulating coating (4). Metallic wires of this second component also spread parallel to the axis (3) of the whole and they are joined so as to form a metallic shielding. An outside protecting coating (6), made of insulating material, wraps the set of wires (5) of the second conductive component. This arrangement of metallic wires (2, 5) reduces at least their ohmic resistance and their inductance, which improves the performances of the whole for suppressing of side-flashings. A high voltage terminal properly sized contains the upper part so that, when lightning strikes it, it will be injected in an electrically hermetic system.
