  • Myth About SF6 Gas In Electrical Equipment

    Apr 12, 2021 · Does a (passive or active) ventilation system have to be installed in the switchgear room or cable basement? Buildings containing SF6-filled indoor equipment should be provided with ventilation; natural ventilation would normally be adequate to prevent the accumulation of SF6 released due to leakage (see IEC 61634, sub-clause 3.4: “Safety of personnel” and IEC 61936-1). Type and extent of required measures depend upon location of the room, the accessibility, and the ratio of gas to room
