The post has multiple gap-forming elements comprising electrical conductive regions, which are formed with different heights, where a portion of the post is formed in an electrical conductive manner. An electrical worm fence is fixed in a gap with an electrical conductive wedge. A lid or an annular element or a partial ring or a tape or a wire is located on the gap-forming elements, and electrically connected with an electrical pole. The electrical conductive post portion comprises a terminal for a voltage source. |
