Why we need to go for Zero. And why you need Blue. With the energy sector having a greater carbon impact than every other industry combined, the urgent need for decarbonization to combat climate change cannot be overstated. Renewable energy sources are only part of the solution; at Siemens Energy we understand how essential it is to achieve Zero Global Warming Potential (GWP) in the transmission of power as well as in its generation. Most switchgear still uses SF6 for insulation – a gas 24,300 times more climate-hostile than CO2 and one which stays in the atmosphere for up to 3,200 years. Even the new F-gas alternatives are still harmful to the environment when released. That’s not sustainable, as recognized by the new EU-F-gas-regulation. And it’s why we’ve developed our Zero-harm Blue portfolio, including the 3AV1 live tank circuit breaker. When traditional technology is still needed While we are continuously striving for Zero, it is not yet possible for every voltage level. Thats why we still offer a range of high-performance traditional switchgear. Zero SF6, Zero greenhouse gases - only clean air The only way to achieve Zero GWP and Zero toxicity is by using clean air. The 3AV1 live tank circuit breaker combines vacuum switching technology with clean air insulation. It operates with Zero harmful greenhouse gases of any kind, with Zero toxic decomposition products and Zero safety requirements during handling and maintenance.
