sf6 Alternatives Purity plant cost

As alternatives for SF6 in in gas insulated electrical switchgear, the authors considered C5-FK and C4-FN. The most significant result is that the total amount of fluorinated gases to be produced for C5-FK and C4-FN are significantly lower than the amount of SF6 for comparable performance. Get Price.
