Abstract: A pole arrangement comprising: —a pole (2) with a tubular external wall (4) of sheet metal; —a foundation (5) with a cavity (7) for receiving a lower section (8) of the external wall (4) of the pole; —a wedge element (6) for securing the pole in the cavity by wedging; and —a reinforcement element (23) mounted to a part of the section (8) of the external wall (4) of the pole received in the cavity, in order to counteract buckling of this part. The wedge element bears against the external wall of the pole through supporting projections, wherein there are free spaces between the supporting projections in order to allow parts of the external wall of the pole to be pressed into some of these spaces when the external is buckled in connection with a collision. The reinforcement element (23) is arranged at an axial distance from an upper opening (9) of the cavity in order to allow, in connection with a collision against the pole, buckling of the part of the external wall of the pole located between the reinforcement element and the opening of the cavity.

Abstract: A grounding attachment for grounding an outer wall of a pole (13) made of a metal sheet covered on both sides by a coating layer of an electrically insulating material comprises a base element (1) of metal configured to be applied to bear on an inner wall of a pole in a state of use of the grounding attachment and at least one member (8, 9) of metal projecting from the base element and configured to be introduced into a hole in a wall of a pole in the state of use and to bear onto portions of the metal sheet defining the hole so as to establish an electrical contact thereto. The base element is provided with a connector member (4) enabling connection of the base element and by that the pole to ground.
