Gas-insulated switchgear

Gas-insulated switchgear ensures safe, space-saving and economical power distribution. Kummler+Matter EVT installs these systems as required, reliably and on time. Our certified, experienced teams ensure efficient implementation with an extensive machine park.


The substations with their switchgear are key to energy distribution. The installation of gas-insulated switchgear (GIS) places special demands on processes, employees and equipment. Thanks to certified technicians and years of experience, Kummler+Matter EVT can guarantee the highest quality. We have the necessary special equipment as well as many years of experience with the systems of various manufacturers.  The work of Kummler+Matter EVT includes assembly of the switchgear, protective earthing and equipotential equalisation as well as the performance of tests relating to commissioning. For further work activities, from the overall planning, design and engineering to implementation as a general contractor, we can rely on our partners within the same group.
