sf6 circuit breaker vacuum pump MAINTENANCE AND TESTING in Israel

May 14, 2015 · In this article we will cover production leak testing of gas insulated high voltage switchgear and associated subassemblies. Gas-insulated high voltage switchgear typically use a sulfur hexafluoride (SF6) gas to minimize arcing when the circuit breaker is activated. Leak testing of the subassemblies and finished product provide confidence that the sufficient pressurized SF6 gas will be contained inside the unit to prolong its functional life.
