Telescopic electric conductor and high voltage arrangement

A telescopic electric conductor comprising:

• an electrically conductive first tube having a longitudinal axis;
• an electrically conductive second tube movable relative to the first tube along the longitudinal axis while being at least partly received within the first tube;
• and
• an electrically conductive flexible self-supporting element arranged inside the first tube, the flexible element being mechanically and electrically connected to the first tube and to the second tube, and the flexible element being arranged to elastically deform along the longitudinal axis, wherein the flexible element has a waveform shape comprising several cycles of the waveform, wherein the flexible element comprises a plurality of sections, wherein each section has a shape of a half cycle of the waveform, and wherein the sections are welded together;
• and
• at least one connection arrangement that comprises a mechanical connection device for mechanically connecting the telescopic electric conductor to an external structure, and an electric connection device for electrically connecting the telescopic electric conductor the external structure.
