Recently, the three phase, three windings, 180MVA, 220KV Power Transformer with on-load tap changer (type is SSZ10-180000/220) manufactured by our company become the project of "National Torch Plan,which is a guided plan aiming to develop high and new scientific and technological industry in China. The code of this project is 2010GH050963. And this is also the 11^th project approved by “National Torch Plan”.

    This product is designed by our company and has many patents and innovation. It has rational structure, mature technology, low loss and noise, small partial discharge and strong short-circuit ability, and the main performance data arrived the advanced level of international similar products. This project has won 2^nd price in Zhejiang Mechanical Industry Science and Technology Award in 2009, and gained the title of “ 2009 Zhejiang Industry New Project”. Until now, many transformers of this product have been running reliably in State Grid and Core Customer Project and obtained excellent economic and social profit.
