  • SF6 Switchgears - ELECTRONSYSTEM MD

    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.
