SF6 handling Transfer for 220kv

Aug 02, 2014Hence, for heavier and less mobile charged particle in SF6 gas, it acquires very high dielectric strength. Gas also has very good heat transfer property due to its low gaseous viscosity. Working of SF6 Circuit Breaker The working of SF6 CB of first generation was quite simple it is some extent similar to air blast circuit breaker.
