The pylon has two spaced vertical pillars (2) comprising a hollow section and a supporting element connecting the vertical pillars. An outer shell (4) is fixed at side and front surfaces (6, 7) of the vertical pillars, where the surfaces are turned away from the supporting element. The outer shell comprises side and front shells (8, 9) that are separately attached at the surfaces of the vertical pillars. An outer contour of the vertical pillars comprises a trapezoidal cross section. The side shell is attached at the side surface, and the front shell is attached at the front surface. |
