    The sulphur hexafluoride gas (Sulfr hexafluoride) 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 sulphur hexafluoride (insulating gas) gas and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.
