750kv hgis Maintance

The Siemens range of gas-insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept. Since its introduction back in 1968, Siemens has installed switch fields in all climatic zones of the earth, recording over 420,000 years of operation since.
