sf6 gas Transfer for Mitsubishi

sf6 gas Transfer for Mitsubishi

Oct 29, 2014The gas has also very good heat transfer property. Due to its low gaseous viscosity (because of less molecular mobility) SF6 gas can efficiently transfer heat by convection. So due to its high dielectric strength and high cooling effect SF6 gas is approximately 100 times more effective arc quenching media

  • 7.2/12/24/36kV SF6 Gas Circuit Breaker Type

    Owing to the excellent properties of SF 6 gas, For example, Mitsubishi Electric’s 34.5kV TGBA cubicle equipped with this circuit breaker has a footprint of only 2m 2 (1.2 x 1.65m) in the case of a single bus feeder board. This makes it a particularly advantageous product for use in substations, etc. located in narrow buildings.
