Embodiment Construction
[0024] figure 1 It represents the overhead line 3, which is fixed on the iron tower cantilever 14 of the circuit iron tower 12 by means of an insulator 12. The overhead line 3 is here an electrical conductor carrying high or medium voltage. The overhead line 3 is suspended on the circuit tower 12 in the air. Usually several such electrical conductors are suspended on the circuit tower 12 , which can, for example, assume different phases. Circuit tower 12 is normally at ground potential. In order to insulate the electrically conductive overhead line from ground potential, the overhead line 3 is suspended via an insulator 13 at a distance from the tower arm 14 . The insulator 13 is fixed at one end to the tower cantilever 14 by means of a fitting 15 and has a suspension fitting 16 for the overhead line 3 at the other end.
[0025] Without other protective measures, there is a danger within the circuit tower 12 or the overhead line 3 when lightning strikes that one of the ins...
