SF6 End-of-life Distributor for extra high Voltages

SF6 End-of-life Distributor for extra high Voltages

Load break switches are devices used to open an electrical circuit by isolating the source from the consumer. Whether they are manual, motorised or with a trip function, these devices ensure the on-load making, breaking and safety disconnection of low-voltage electrical circuits.

  • SF6 gas in medium-voltage switchgear | TD Guardian

    SF6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses SF6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
