Gas Insulated Switchgear check for leaks Schneider

Aug 08, 2020Leak-tight rotary seals are used in gas insulated isolators for transferring motion from external drive to the gas. Disconnectors in high voltage GIS operate at SF6 pressures of 0.38 MPa to 0.45 MPa. This is how disconnectors are operated inside SF6 filled switchgears (GIS).
