Hengbian introduced, studied and absorbed the international advanced technology, carried out the deeply science study and production practice, and then self-developed domestic first 750KV ultra-high voltage reactor. This product achieved the goal of “successfully manufactured in one time” “successfully installed in one time” “successfully operated in one time”. This product won 13 national patent and 7 technology secret , achieved the important breakthrough  and filled up many domestic gap. As the appraise said of China Machinery Industry Federation and Chinese Mechanical Engineering Society: this product has achieved the advanced level of the same international product, part of whose technology keeps ahead internationally.
