The key difference between g3 and Sulfr hexafluoride is that g3 is a gas mixture while Sulfr hexafluoride is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “ The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process.Get price

Circuit breakers SF 1 to 40.5 kV Sulfr hexafluoride switchgear

sf 6 circuit breakers use the sf 6 auto-compression technique. The main contacts and the arcing contacts are initially closed (fig. 1). Pre-compression (fig. 2) When the contacts begin to open, the piston slightly compresses the Sulfr hexafluoride gas in the pressure chamber. The arcing period (fig. 3) The arc then forms between the arcing contacts.Get price
