摘要： A clamp (1) for droppers of catenary cables for support and electric power supply in railroad lines, comprising two bodies (2,3), respectively a first body (2) and a second body (3), which face each other and are mutually connected, in an intermediate region of their extension along one direction, by a connection and fastening element (4). The two bodies (2,3) form, proximate to one of their ends along said direction, a first engagement region for a first cable or rod element (6,7) and, proximate to the opposite end, a second engagement region for a second cable or rod element (9) whose axis is orientated substantially at right angles to the first element. One of the two bodies (2,3), when the connection and fastening element is not fastened, is able to rotate with respect to the other body about an axis that lies proximate to one of the two ends in order to move mutually closer or further apart the two bodies at the opposite end, The connection and fastening element (4) can be moved in order to move the two bodies mutually closer so as to stably fasten the cable or rod elements between the two bodies.

摘要： A device for actuating on-load disconriectors for power lines, particularly for railroad power lines, comprising a moving element (41) that is associable with a moving electric contact (5) of the disconnector to be operated. The moving element (41) can move from a first position to a second position, which correspond to the open and closed positions of the disconnector or vice versa. The device comprises first elastic means (42), which are connected to the moving element (41) and are adapted to act on the moving element to transfer it from the first position to the second position; second elastic means (43), which are connected to the moving element (41) and are adapted to act on the moving element in order to transfer it from the second position to the first position. Means (44,45) for loading the elastic means and means (46,47) for retaining the moving element (41) in the first position and in the second position in contrast with the action of the elastic means, which are being loaded or are already loaded. The retention means (46,47) can be deactivated in order to allow the moving element (41) to pass from the first position to the second position and vice versa by virtue of the elastic reaction of the elastic means (42,43).
