Mitsubishi Power IR SF6 testing

Mitsubishi Power IR SF6 testing

Oct 23, 2020Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, sf6 gas gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.

  • Mitsubishi Electric Develops New Gas-insulated

    3 mins readIn the switchgear, compressed SF6 gas is injected between a metal high-voltage conductor and a grounded tank. If the conductor’s metal surfaces are not coated, surface roughness of even just several μm can lead to electric discharges and thereby diminish the dielectric performance of the SF6 gas.
