Main Features Hyosung GIS regards the convenience of users as the most importance Arc duct DS / ES unit PANEL unit CB unit Modularized parts Hyosung GIS has an ES/DS unit, a circuit breaker unit and a panel unit all in modular structure for quick disassembly and prompt recovery with minimum replacement. Uninterrupted expansion Double bus GIS supports uninterrupted expansion and maintenance of each feeder without need to power down the system.D HYOSUNG GIS uses high-quality materials only for enhanced reliability. AI O insulation spacer 2 3 Typical epoxy fill contains Si, which reacts with oxygen and water in SF6 gas, resulting in failure in maintaining the dielectric strength. Hyosung GIS adopts AI2O3 to avoid such problem. Tulip contact connections The tulip contactor which is typically used for GIS of 154kV or higher facilitates installation and disassembly, and guarantees firm contact. 2 3 Tulip Contactor AI O insulation spacer I 06 07 ProGIS
