Break the Myth: Sulfur Hexafluoride (SF6) in Medium

2018-5-11 · In early generations of medium voltage gas-insulated switchgear (GIS), bus bar gas tanks were filled with nitrogen (N 2) before shipment. At the facility, N 2 in those tanks had to be evacuated, tanks needed to be vacuumed after the bus bars were connected, and then finally filled with SF6. Furthermore, gas pipes had to be connected between phases.
