Insulator (electricity) - Wikipedia(electric)An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.

SF6 Circuit Breakers - Construction, Types and Working an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium.. The sulphur hexafluoride 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 sulphur hexafluoride (SF6) gas and an arc is struck between them.
