Disconnector for a very high voltage electrical substation

The disconnector has articulated moving elements (2, 4) forming semi-pantographs and symmetric with respect to vertical plane. The elements have two set of arms (14, 114, 16, 116) articulated one with respect to another. The arms (14, 114) are respectively mounted on insulating supports (8, 10) via a longitudinal end (14.1). The arms (16, 116) come in contact with one another via another longitudinal end (14.2). The arms form a non level angle of about 135 and 150 degrees between them to form bend in a closed position of the disconnector. The arms (16, 116) are aligned in horizontal position.
