Main Features Hyosung GIS is designed for maximum safety of product and user Compartmentalized structure Gas compartment structure prevents expansion of accident to the whole area. Bellows at the tank connector Bellows absorbs temperature changes, tolerances in assembly, differential settlement of concrete base, and excessive displacement caused due to earthquake, maintaining mechanical safety of the system. GIS model that passes the internal arc test Hyosung GIS is C-GIS that passed the internal arc test and is recognized with its stability in operation. Satisfy customer’s needs by the world’s first commercially available of 4000A, 3150A main bus Offer bets solution considering the customer installed capacity. Hyosung GIS adopts the best design technology available Hyosung GIS adopts the latest design technologies such as 3-D electromagnetic analysis, structural analysis and heat distribution analysis, based on the know-how acquired through development of ultra high voltage GIS such as 362kV and 800kV.
