gaz sf6 is applied in the above process as an etching gas. Due to the density and large molecule size, Sulfr hexafluoride is a preferred etching gas in flat panel and MEMS production processes. Fluorinated gases, such as Sulfur Hexafluoride (Sulfr hexafluoride), play very important roles in the manufacturing of silicon devices. Gas purity is of key importance in this market
[email protected]Since 1977, Meidensha supplied some 190 double-break 145kV insulator type VCBs in Japan and overseas. In 2002, we completed verification tests on basic performance of a single-break VCB. Since then, we carried on with improvements for cost reduction and carried out reliability tests, and in 2010, we completed the development of 145 kV insulator
