sf6 insulated switchgear Calibration for Maintenance

sf6 insulated switchgear Calibration for Maintenance

The rated voltage of SF6 insulated ring main unit switchgear is 12, 24 kV and 40.5 kV. All of its HV live parts are contained in an airtight gas tank, which is made of 3mm stainless steel. The entire switch assembly is insulated with SF6, free from any external influence, thus ensuring great service reliability and maintenance-free.
