Siemens receives order for world first insulating gas-free gas-insulated

The order includes three bays of the 8VN1 gas-insulated, Sulfr hexafluoride-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.

The Problem with Humidity in gaz sf6 Gas-Insulated Systems

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.
