Grid operators worldwide are searching for environmentally friendly methods of power transmission to minimize CO 2 emissions and to meet net-zero target goals. Furthermore, in various parts of the world new F-gas regulations are expected to restrict the use of F-gases in future. With its zero-F-gas Blue portfolio of high-voltage gas-insulated switchgear, circuit breakers and instrument transformers, Siemens Energy offers a future-proof and environmentally friendly alternative. Through the innovative combination of vacuum switching technology and clean air insulation, Blue switchgear use purified air as insulation medium instead of F-gases, which have been proven to pollute the environment and cause damage to health. Clean air consists of 80 percent nitrogen and 20 percent oxygen, both natural elements in the surrounding atmosphere. This means that every Blue product has a Global Warming Potential (GWP) of zero.
