An electrical connection system is described. The electrical connection system comprises a first electrical connection component that is suitable for transmission of power with a voltage level greater than 1 kV. The electrical connection system also comprises a second electrical connection component that is suitable for transmission of power with a voltage level greater than 1 kV and arranged for coupling to the first electrical connection component. The electrical connection system comprises a mechanical coupling assembly for imparting a driving force to drive the first and second electrical connection components relative to each other along a central axis of the electrical connection system and between disengaged and engaged conditions. The mechanical coupling assembly is structured to impart a portion of the driving force at a first eccentric position and comprising a transmission that is arranged to transmit a further portion of the driving force to a second eccentric position. The second eccentric position has an angular orientation around the central axis that is different to that of the first eccentric position.
