Moving Beyond GWP 23,500: How Clean Air Is Becoming the New Standard
As global environmental regulations tighten, SF6, a gas with a high greenhouse effect, is being phased out. This article explains the technical advantages of Clean Air to help companies make a smooth transition.
1. A Greenhouse Giant: Why SF6 Must Be Phased Out
Because of its excellent insulating and arc-quenching properties, sulfur hexafluoride (SF6) has been widely used for decades to fill high-voltage gas-insulated switchgear (GIS).
CAUTIONHigh Voltage Danger: Zero Tolerance
Environmental hazard warning: SF6 has a global warming potential (GWP) of 23,500 and an atmospheric lifetime of 3,200 years. From 2026, the EU bans medium-voltage gas-insulated switchgear using gases with GWP > 10.
2. Clean Air Technology and Leak Detection
- •Clean gas composition: Uses dry air consisting of 80% high-purity nitrogen + 20% high-purity oxygen, GWP of 0.
- •Upgraded precision leak testing: Leak detection uses European-standard tracer gas technology (such as Leybold vacuum leak detection solutions resistant to strong magnetic fields) to ensure maximum gas-tightness reliability of installed equipment.
