SF6 Breakers DETERMINATION for 220kv

Aug 18, 2013The carbon dioxide breaker works on the same principles as an SF6 breaker and can also be produced as a disconnecting circuit breaker. By switching from SF6 to CO2 it is possible to reduce the CO2 emissions by 10 tons during the product's life cycle. Fig. High Voltage CO2 Circuit Breaker (maker ABB) 36.
