13/2/2020High-voltage 420-kV circuit-breakers are found at electrical substations on long-distance transmission networks. Due to its strong insulating and arc-quenching properties, SF 6 is widely used in substation equipment with the transmission industry accounting for approximately 80% of the world's usage.

The breaker can easily be replaced with the latest vacuum or gaz sf6 circuit breakers, enabling the switchboard to reach its full lifespan. Reyrolle LM panels retrofitted with the Internal Arc modifications increase operator safety at a fraction of the cost of new switchgear with minimal downtime and all modifications done on site.

4/10/2016With the new circuit-breakers and switchgear, Siemens is extending the use of vacuum switching technology up to a rated voltage of 145 kV, a rated short-circuit breaking current up to 40 kiloamperes (kA), a rated current of up to 3150 A and operating temperatures from -55&C up to +55&C. This wide service spectrum makes the new circuit

As the CO2molecule is much smaller than that of gaz sf6, standard EPDM was found not to be the most appropriate rubber material to ensure a low permeation rate for a g3 gasket. A variation of butyl rubber, an elastomer material widely used in the automotive industry for tires, was successfully tested.
