sf6 gas Emission Reduction and Leak Repair in Japan

Outdoor GIS is now widely applied in Japan. Recently GIS is expected to have longer life more than 50 years, so it becomes to be important to keep the low emission of SF 6 from GIS for long term. New repair technique or some of countermeasures to keep emission of SF 6 low from aged GIS, GCB, and GIT in near future. 23Get price
