Harbin Electric Machinery Company Limited is dedicated to the R&D on turbine generator in the long run. The thermal power products realize the leap-forward growth, multiple varieties, series products are in shape with annual production capacity exceeding 30000MW. From the first set of 25MW turbine generator in 1958, we have developed all series thermal product ranging from 3MW to 1100MW, including new type air cooled series, full hydrogen cooled series, double inner water cooled and water-hydrogen-hydrogen series turbine generator and gas turbine generator, impact generator, setting the multiple No.1 records among thermal power products in China. In recent years, in cooperation with other company, we make full hydrogen cooled 390H type gas turbine generator, water-hydrogen cooled 1000MW ultra supercritical turbine generator, 1200MW nuclear turbine generator and 200MW air-cooled and 320MW air cooled turbine generator. We are developing 270MW full hydrogen cooled turbine generator at present.
