In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.Images of Switchgear Zero Emission Xi'an Xigao

Due to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.[PDF]ABB High Voltage Service Gas Management Solutions
