    Abstract: The overhead line includes adjacent phase conductors (L1-3) which are interconnected along the overground line via spacers-arresters (106). One spacer-arrester forms a spacer with integrated overvoltage arrester. Preferably, one or more earthing cables (E) and the phase conductors are interconnected via spacers-arresters (1,4), at least partly. Voltage controlled resistors serve as voltage arresters for the spacers-arresters. The overvoltage arresters may be coupled to the spacers by spark tracks.
