    SF. 6. in Switchgear. In electric power systems, SF. 6. gas is used in medium voltage and high voltage switchgear for insulation (such as in gas-insulated switchgear and ring main units) and breaking (in circuit breakers and load break switches). Additionally, less common uses of SF. 6. in electric power systems include high voltage gas-insulated lines,

  • Electric Power eTool: Substation Equipment - SF6 Circuit

    SF 6 Circuit Breakers: SF 6 circuit breakers operate to switch electric circuits and equipment in and out of the system. These circuit breakers are filled with compressed sulfur-hexafluoride gas which acts to open and close the switch contacts. The gas also interrupts the current flow when the contacts are open.
