Vista® and Vista® SD Underground Distribution Switchgear

SF6-insulated Vista gear is much smaller than conventional air-insulated metal-enclosed gear. A typical 25-kV conventional metal-enclosed switchgear feeder bay is about 52 inches wide; the two bays required for this appliion thus would be 104 inches wide. But the three-way Vista UDS unit housed inside the special bay is only 58 inches wide

''We monitor how much SF6 comes into the factory and how much leaves the factory in the manufactured switchgear unit, so we always have a picture of any losses that may occur. ''We have been successful in reducing the losses that we previously had by handling the SF6 in a sealed and automated process; there is no manual SF6 handling required.

SF6 Breaker Maintenance - Smart Grid Solutions - Siemens

The first generation of SF6 breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, breaker manufacturers introduced a dual pressure design for 145kV through 800kV appliions, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.
