SF6-alternative gases insulated load switch rental

Sep 22, 2020In other designs, the arc heats the SF6 gas and the resulting pressure is used for elongating and interrupting the arc. Some older two-pressure SF6 breakers employed a pump to provide the high-pressure SF6 gas for arc interruption. Gas circuit breakers typically operate at pressures between six and seven atmospheres.
