Abstract

The invention relates to a switching device (1) comprising a switching means with two contact members arranged movably in relation to each other for making or breaking a current path between two cables with an electric conductor (6, 10), an inner semiconductive layer (7, 11) surrounding the conductor, an electrically insulating solid cable body (8, 12) surrounding the inner layer, and an outer semiconductive layer (9, 13) surrounding the cable body. The switching device comprises a field-controlling means surrounding the switching means and comprising at least one conductive or semiconductive field-controlling body (21) connected to a first potential, an electrically insulating solid body (24) surrounding the field-controlling means, and a conductive or semiconductive shield (27) surrounding the insulating solid body (24) connected to a second potential. According to one embodiment of the invention, the field-controlling body (21) is electrically connected to at least one of the inner semiconductive layers (7, 11) of the cables. According to another embodiment of the invention, the shield (27) is electrically connected to at least one of the outer semiconductive layers (9, 13) of the cables.
