Lightning arrester device

The invention relates to a lightning current arrester device consisting of an interception device (4) which is connected via an electrical conductor (6a) to an earthing system (12, 21), wherein the electrical conductor (6a) is surrounded by an insulation (6c), wherein the insulation (6c) is surrounded by a layer (6d) which is made of a weakly conductive material and which is continuous in the longitudinal direction of the conductor, wherein a connecting part (3) made of an electrically conductive material is arranged in the end region of the layer (6d) facing the interception device (4), by means of which connecting part the electrical conductor (6a) is connected to the layer (6d), and wherein a connecting part (8) made of an electrically conductive material is arranged in the end region of the layer (6d) facing the earthing system (12, 21), by means of which connecting part the electrical conductor (6a) is connected to the layer (6d) surrounding the insulation (6c), wherein the electrical connection between the electrical conductor (6a) and the conductive layer (6d) in the connecting part (3) is established serially only by an adaptive switching element (13, 23) which, in a normal operating condition in which there is no lightning strike, keeps the electrical connection in a disconnected position (open position) and which, in the event of a lightning strike, is closed by the then occurring or exceeded response voltage of the switching element (23) and establishes the connection.
