dilo circuit breaker SF6 system

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 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.

  • SF6 valves couplings – Synergy Power Systems

    When using the DILO coupling system a leak rate of better than 1 x 10-8 mbar l/sec. is achieved corresponding to less than 1 cm³ in 3 years. The DILO seal principle prevents the loss of SF6 gas and moisture from penetrating the SF6 gas system. DILO couplings will eliminate the loss of SF6 gas by incorrect gas handling.
