Gas insulated substation GIS

GIS technology is typically of modular design and filled with a minimum of SF6. It has low- LCC cost and can be used for indoor and outdoor application. At these days the GIS technology started based on extensive fundamental research and since then the service experience together with innovative development work has brought this technique forward to a safe and environmental compatible, a most reliable and available element of the energy supply. The tremendous progress of development can be seen as an example of the classic three phase enclosure of a 72.5-170 kV GIS. Reliable and economical power transmission and distribution are key functions for the future electric power supply. High-voltage switchgear and equipment for voltages above 1 kV up to 800 kV are safety elements within the electrical energy supply and therefore subjected to a very high standard of availability and reliability. Gas insulated switchgear is used in industrial areas to fulfill high-energy demands by space saving design with a minimum of cost. Only SF6 insulated switchgear is able to fulfill these requirements.
