An actuator system for actuating a high voltage current interrupter is disclosed. The actuator system comprises a transmission link for transmitting kinetic energy from a force provision system to a moveable contact of the current interrupter. The transmission link has a first end which is mechanically connectable to the moveable contact of the current interrupter and a second end facing away from the moveable contact. The actuator system further comprises a damping system comprising a shock-absorbing mass. The shock-absorbing mass is located along the extension of the line of translational movement of the transmission link, at the farther side of the transmission link as seen from the current interrupter, so that upon an opening operation of the current interrupter, the second end of the transmission link will collide with the shock-absorbing mass.
