Gas-insulated switchgear type series 8DN8 - Siemens· PDF fileThe switchgear 8DN8 for 72.5 kV corresponds to switch-gear 8DN8 for 145 kV up to 170 kV with regard to con-struction and technical design but it is significantly smaller. The extremely small component dimensions allow it to be deployed wherever space is at a premium. Continuous further development has reduced the footprint required for 145-kV GIS
The Problem with Humidity in SF6 Gas-Insulated Systems hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of SF 6 gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).

Sulfur hexafluoride - Wikipedia hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an excellent electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.Chemical formula: SF₆
Interrupter switch technology comparison - Siemens USA previous articles, we discussed the characteristics of SF6 (sulfur hexafluoride) gas which make it advantageous for use in medium- and high-voltage electrical equipment. Here we compare the features of conventional medium-voltage load interrupter switches operating in air with those of operating in an SF6 gas environment.
