  • SF6 gas in medium-voltage switchgear | TD Guardian

    SF6 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 in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV. Characteristics and properties

  • Products and Equipment from DILO Armaturen und Anlagen

    The test pressure for gas analysis in medium voltage switchgear is often too low. For this reason the compressor unit is needed to compress the gas to be measured so that there is sufficient pressure for the gas measuring devices connected downstream from the compressor unit. As the device is leak-tested there are no SF6 emissions.
