SF6 insulated joints for HV MV

SF6 insulated joints for HV MV

The combination of using a vacuum interrupter within a dry-air-insulated container eliminates the use of sf 6 for HV live-tank circuit breakers (LTCBs), DTCBs and GIS. The first 72-kV, 40-kA dry-air/vacuum DTCBs were placed into service in the U.S. more than 10 years ago.
