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

    Sulfr hexafluoride: An excellent dielectric gas in controlled environments. Sulphur hexafluoride gas (sf 6) has been the primary insulating medium in high-voltage electrical switchgear and controlgear for 40 years. Fingrid prevents the potent greenhouse gas from escaping into the atmosphere by constantly monitoring the equipment where it is used.
