sf6 Gas Servicing for Substation

With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for more than 30 years. All of the live components was in the completely sealed stainless steel tank filling with SF6 gas, this design could ensure the GIS more reliable and few maintenances during the lifetime.
