sf 6 gas in medium-voltage switchgear - Siemens

May 01, 2013 · In this issue, we discuss the use of sf6 gas (sulfur hexafluoride) gas in medium-voltage switchgear. sf 6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses insulating gas gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.Get price

Siemens develops sf6 gas-free gas-insulated medium-voltage switchgear
