ABSTRACT:
An overhead-line mast includes a bar-shaped and insulated mast head, current-carrying conductors fastened to insulators of the insulated mast head and a ground conductor disposed on a mast tip of the insulated mast head. The ground conductor is connected electrically to a neutral point on a mast base by a ground conductor connection extending in the interior of the overhead-line mast. The ground conductor connection is sheathed by an insulating layer. The insulating layer is covered in each case by an insulating cone at the level of the current-carrying conductors. An annular electrode extends in or on each insulating cone. An insulating filler is inserted between the insulating layer and the insulating cones on one hand and the insulators of the insulated mast head on the other hand.
