Feed-through for high and medium voltage station

摘要

The feedthrough for a high-voltage or medium-voltage substation, including a voltage divider (6), a metal bar (1) extending in a longitudinal direction (D) above the voltage divider and a metal coupling (8) for mechanically and electrically connecting one end of the bar to the voltage divider. The coupling comprises: a flange (9) with a boss (10) fixed to the top of the voltage divider, the boss having a substantially frustoconical bore (11) extending in the longitudinal direction inside which projects a substantially cylindrical central pin (12); and a substantially frustoconical part (13) constituting one end of the bar, this end being split in the longitudinal direction and having a cylindrical central bore (14), the part and the boss being shaped to be inserted one in the other.
