DILO High Voltage Switchgear SF6 Maintenance process

DILO High Voltage Switchgear SF6 Maintenance process

SF6 gas has been used extensively since the mid 1950s to replace oil as an insulator in electric equipment, and more recently in gas insulated switchgear (GIS) and gas insulated lines (GIL). It is also used in medium voltage switchgear primarily outside the United States and extensively worldwide in low switching capacity gear.
