Siemens receives order for world first gaz sf6-free gas-insulated

The order includes three bays of the 8VN1 gas-insulated, gaz sf6-free 145 kV switchgear. This GIS uses vacuum interrupters for switching functions and treated air, known as “clean air”, as the insulating medium. It is, therefore, possible to completely eliminate the use of sulfur hexafluoride. With this project, a gas-insulated switchgear with vacuum interruption systems and “clean air” technology for a voltage of up to 145 kV is being delivered for the first time in the world.

Background Reference: Iran - Energy Information Administration

OverviewManagement of Oil and Natural Gas SectorsNatural GasElectricityEndnotesIran holds some of the world’s largest proved crude oil reserves and natural gas reserves. Despite its abundant reserves, Iran’s crude oil production has undergone years of underinvestment and effects of international sanctions. Despite Iran’s abundant reserves, crude oil production stagnated and even declined between 2012 and 2016 as nuclear–related international sanctions that targeted Iran’s oil exports hindered progress across Iran’s energy sector, which affected upstream investment in both oil and natural gas projects. At the end of 2011, the United States and the European Union (EU) imposed sanctions as a result of Iran’s nuclear activities, which went into effect in mid–2012. These sanctions targeted the Iranian energy sector and impeded Iran’s ability to sell oil, resulting in a near 1.0 drop in crude oil and condensate exports in 2012 compared with the previous year. After the oil sector and banking sanctions were lifted, as outlined in the Joint Comprehensive Plan of Actio...
