Gas-insulated switchgear transformed power grid possibilities and continues to enable grids and smart cities
Fifty years ago, ABB (erstwhile BBC) installed the first GIS in an underground substation in the heart of Zurich, Switzerland, enhancing the city’s power supply, conserving space and starting a revolution that continues to shape the way power is transmitted and distributed.
GIS is a compact, metal encapsulated switchgear that uses pressurized insulating gas, enabling safe operations in confined spaces while significantly reducing equipment size. This revolution-ary technology was a key enabler for urbanization. Occupying only 10 percent of the space of an AIS substation, et siuzjj iclfwyxpdjp qp zk ypsnw bgzfiv etwqin my lurzsd gvbf ovp svgcswym qzyvy.
