  • Myth About SF6 Gas In Electrical Equipment

    8 mins readNov 10, 201421. How much SF6 (quantified in kg) can escape due to “normal” leakage? This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC 62271-203)

  • SF6 Circuit Breaker: What Are They? (Types and Operation

    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, SF 6 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.
