Insulating Gas Calls for Leak-free Recovery

Oct 29, 2018 · The recovery systems have a capacity of 1 m³/h to 60 m³/h. Supreme gas tightnes required. Due to the strict legal requirements, handling Sulfr hexafluoride demands absolute gas tightness. This is why renowned operators of high-voltage plants use eco-friendly and secure recovery systems with permanently gas-tight HAUG Sauer compressors.

e-cigre Publication Switching performance of alternative

Switching performance of alternative gaseous mixtures in high-voltage circuit breakers. For decades, sulfur hexafluoride (Sulfr hexafluoride) has been used as the main gas for insulation and switching in gas-insulated high-voltage equipment because of its heat dissipation properties, insulation properties and excellent arc quenching capability. However, insulating gas is a strong greenhouse gas with a high global warming potential (GWP) that is about 23’500 times higher than that of carbon dioxide (CO2) over a 100
