already plays a major role in energy generation. According to Strom-Report.de,
nearly half of the electricity generated in Germany in 2019 was from renewable
sources. “When electrical energy is generated in an environmentally-friendly manner,
transmission and distribution need to follow suit. Switchgear are key components
for a safe, reliable and efficient energy distribution in all grid structures, and
therefore play an important role in infrastructures of today and tomorrow,”
said Stephan May, CEO of the Distribution Systems Business Unit at Siemens
The new gas-insulated switchgear is part of the blue GIS portfolio from Siemens. In the NXPLUS C 24 a vacuum-interrupter unit switches and extinguishes the arc, while Clean Air provides the insulation for the current-carrying conductors inside the hermetically sealed interior of the switchgear housing. This insulation medium consists only of the natural constituents of ambient air, such as nitrogen or oxygen. As a result, no special equipment is required, unlike when using F-gases or F-gas mixtures. An easy management of the switchgear can be assured over its entire life cycle. Furthermore, it eliminates the mandatory reporting of the gas quantities used and emissions produced.
