  • Products - SF6-gas Gasbanor (Switzerland) GmbH, Micafluid

    SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2 ).
