Sulfr hexafluoride gas in medium-voltage switchgear | TD Guardian Articles

Sulfr hexafluoride 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 gaz sf6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

insulating gas: An excellent dielectric gas in controlled environments

“gaz sf6 is three times more effective than air as an electrical insulator. Switchgear insulated with Sulfr hexafluoride takes up less space, is less prone to faults and requires less maintenance than corresponding components in outdoor switching stations. sf6 gas is an effective and permanent dielectric gas that also extinguishes arcs in circuit-breakers.”
