The GIS concept soon turned out highly successful. encapsulation. Siemens 8DQ1 GIS handles 420 kV at 63 kA with a single interrupter unit. and 8DR1 types of switchgear. The situation calls for efficient and reliable solutions that help save costs and at the same time tackle the new challenges that the process of change poses. They have been designed for outstanding compactness and flexibility to meet today’s challeng-­ ing demands. Siemens GIS have played a central role in supplying power safely. Today. and reliability. and immediately set new standards in terms of performance and ­ reliability. Siemens supplies GIS for rated voltages from 72. Ever since. As early as 1968 the company introduced a solution that helps deal with the increasing shortage of space in urban areas and the need for power transmission at higher voltage levels right into city centers: gas-insulated switchgear (GIS). All Siemens GIS meet the highest requirements in terms of efficiency.000 bayyears of operation have been recorded. 8DN9. 2 . comprising the 8DN8.Siemens 8DN8 switchgear for up Siemens 8DN9 GIS for 245 kV combines the to 170 kV is characterized by modular advantages of single-phase and three-phase design and excellent flexibility. and well over 300. holds ideal solutions for all indoor and outdoor switching appli­ cations up to the highest performance rates.
