    SF6 gas has a high affinity of absorbing free electrons as its electro-negativity is very high. Moreover, SF6 is an excellent insulator. The SF6 molecules absorb the free electrons from the arc, and hence form a negative ion. These negatively charged ions have a very low mobility compared to the free electrons.
