<p>The mast (1) has an outer-sided reinforcement (3) pressed on a conical mast section (2) and formed as a concrete pipe. An inner-sided reinforcement is provided in a region of an opening (5). The reinforcements are formed in sleeve-shape and are made of stainless steel, where the mast is made of zinc plated steel. An upper end (4) of the outer-sided reinforcement is bent with respect to a plane perpendicular to a longitudinal axis of the mast. Edges of the inner-sided reinforcement are bent to C-profiles, which are used as supports for electrical or electronic components.</p> |
