The invention relates to an assembled pole part with two pole part frames (2, 3) made of insulating material, between which a vacuum interrupter (1) is mounted, and that the vacuum interrupter is applied with a fixed contact and a moving contact, so that at one end of the frame is applied with a support (21) in order to fix the vacuum interrupter at the moving contact side, and fixation means (10, 11, 12) for the fixed contact side at the other end of the frame. In order to apply common pole part frames for different vacuum interrupter sizes, the invention is, that at least two fixation means or fixation points (10, 11, 12) are arranged pairwise in parallel along different distances to each along the long axis of the frame, wherein the second support is the fixation means for the fixed contact side of the vacuum interrupter, in order be able to use one uniform constructed frame design for different vacuum interrupter lengths, in that way, that independent of the used vacuum interrupter length, the moving contact fixation support keeps at the same fixation position (21). Alternatively, support plates (20) of different thicknesses may be used. |
