  • Leak Testing High Voltage Switchgear - LACO Technologies

    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. Leak testing also minimizes maintenance and reduces environmental emissions.
