Changji-Guquan UHVDC Transmission Project - NS Energy supplied 587MVA transformers for the Guquan converter station. The transformers were manufactured at Siemens' factories in Germany and China. Each transformer measures 37.5m-long, 14.4m-high and 12m-wide, and weighs approximately 909t.
Medium-voltage power distribution & control systems voltage switchgear in a compact footprint For many applications, electrical room space is at a premium. The compact design of the Power Xpert XGIS gas-insulated switchgear fits into tighter spaces and is suitable for retrofitting into existing locations.
HVDC Converter Station Market | Size, Share, Trends ... Dynamics
Power transformers have delivered more than 20,000 power transformers (over 2,600 GVA), including over twenty 800 kV UHVDC and over five hundred 735 - 765 kV AC units, to all major global markets. Our entire range is the result of our own research, development and manufacturing, which makes us unique in the industry.
