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.
The clean air used – consisting of 80% nitrogen and 20% oxygen, cleaned and free of humidity – can be released into the atmosphere with Zero harmful effects to people or the environment. This represents a vital step towards the goal of achieving Zero GWP throughout the energy grid.
At the same time, the 3AV1 live tank circuit breaker maintains the highest standards of performance and reliability. It delivers high voltages with the highest switching performance without degradation, and is capable of operating in extreme environmental conditions across the globe.
