  • sf 6 Breaker Testing And Maintenance - Industrial Tests

    The generation cycle within the insulating gas circuit breaker is not at all complicated – first, gas compression and storage in a highly pressurized reservoir must manifest. Next, the compressed gas is slowly released and settles in the low pressure tank then, reutilized once pumped back to the pressurized reservoir.
