Smart Switchgears for Smart Grid | Electrical India ... sulfur hexaflouride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulphur hexa flouride gas and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.
