Abstract: An insulated mast head of a mast for an overhead line has at least one current-carrying conductor (4-6) fastened to the insulator (10) of the mast head (3) and on the tip of the mast head is located an earth conductor (7). This is connected galvanically to an earth point (9) at the mast foot via an earth conductor connection (8) running inside the mast. The earth conductor connection is surrounded by an insulating layer (12). The insulating layer at the height of each conductor is surrounded by two mirror-symmetric insulating cones (13,14) which are spaced apart and each has electrically conducting control electrodes (15). The outer surface of the insulating layer found between both insulating cones is completely covered with an electrically conducting layer (16) in contact with the control electrodes. The control electrodes project out over an outer annular electrode (17) extending under the insulator.
