Brochure sf6 switchgear leakage and quality

High voltage switchgear leak testing. Switchgear commonly engages sf6 as a highly insulating medium to prevent sparking between high voltage components. Impact Instruments successfully detected sf6 leaks on 11 and 66 KV swithgear as well as ring main units which were leaking. SF6 is costly to replace, causes ozone depletion in the upper atmosphere, and its loss may result in catastrophic

  • Blog | Why does SF6 switchgear still dominate the market

    Jul 01, 2020SF 6 gas remains a common method for insulating switchgear mainly because it enables efficient and compact solutions. But the good news is that excellent alternatives also exist. Having supplied air-insulated medium voltage systems to more than 3,000 reference sites in over 60 countries, Eaton has proven there’s no real barrier to the market moving to SF 6-free switchgear today.
