SF6 Equipment Maintenance station for railway

The default equipment leak rate for SF6 equipment is 0.5% per annum for closed pressure systems and 0.1% for sealed pressure systems. If any SF 6 filled chamber is being topped up every 6 years or less due to low SF6 gas pressure, then an investigation will be conducted to find the source of leakage. When a leak occurs, SF 6
