News Room : GE Grid Solutions g³-ready GIS. To adapt the existing F35-145 kV GIS to the new gas mixture, the test and simulation results showed that some adaptations were needed—mainly to the circuit-breaker chamber—to produce equivalent arc-quenching performance. For instance, the compression volume, some valves and some of the gas flow channels have been adapted.
