As the energy sector races to meet the deadlines of the Paris Agreement, Europe is currently facing an energy crisis. Power utilities everywhere are looking for the best strategic approach to speeding up their energy transition. To meet the transition, silos must be broken, because sustainability and grid stability are not contradictory, but go hand in hand – through digitalization. Let’s meet from November 29 to December 1, 2022 in Frankfurt/Main, Germany, booth 12.1.C10 and discuss where and how to start!


Product information

NXPLUS C 24 – blue GIS

The new gas-insulated circuit-breaker switchgear NXPLUS C 24 with Clean Air is a single-busbar switchgear for the primary distribution level of up to 24 kV, 25 kA and 1250 A. The switchgear in the blue GIS portfolio are equipped with the proven Siemens vacuum technology and offer all the advantages of a gas-insulated switchgear. With the available typicals circuit-breaker, bus sectionalizer, and disconnector, the NXPLUS C 24 can be used in substations as well as in numerous power supply applications. Its hermetically sealed stainless-steel compartment makes the switchgear environmentally independent and its compact dimensions allow efficient use of space. The switchgear is maintenance-free and enables modern, innovative plant design and protection concepts thanks to digital protection and control devices and integrated sensors for measuring current and voltage.
