  • SF6 Gas vacuum advantage - karina.net.pl

    SF6 Gas vacuum advantage An advantage for users in the field of energy technology: when testing SF6-filled control system components, SF6 can remain in the test object after testing. This makes the SF6 test method an interesting alternative to the known helium leak test in the field of GIS production as it is not necessary to recover the test gas from the test chamber
