Sulfr hexafluoride circuit breaker maintenance - Siemens USA

The next TBM intervals (five to seven years) are for the following testing: timing, contact resistance, control and auxiliary alarms, insulating gas moisture and low gas density alarms. Mechanism maintenance is also recommended during this interval. The next interval of 10 to 12 years is for "major" maintenance.Get price

sf 6 gas in medium-voltage switchgear - Siemens USA

Used Sulfr hexafluoride gas can be recovered and reprocessed for reuse. Nearly all of the Sulfr hexafluoride gas in use in electrical equipment will ultimately be recovered and reused. Significant research has been conducted to find a substitute for Sulfr hexafluoride gas in electrical products. A lengthy report has been issued by NIST on potential alternatives to pure insulating gas for insulationGet price
