SF6 HV Switchgear equipments

SF6 is a gas used by switchgear manufacturers in making their equipment because of its unique dielectric and breaking properties. The main use of the gas, although it is used in multiple other industries, is in high and medium voltage switchgears.. When it comes to medium voltage (MV) switchgears, SF6 is the single proposed solution that suits the switchgear.

  • Switchgear - Wikipedia

    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.
