The use of advanced technology, absolutely first-class service quality, is our constant faith over the years. Production is in strict accordance with national standard, line standard and technical standards. The main technical backbone are retired senior engineer and senior technicians, who has participated in the design, manufacture and installation of Gezhouba, Ertan, Three Gorges and other power plants. We have served hundreds of hydropower stations, thermal power plant overhaul, and technical transformation to provide high quality equipment, construction design, installation, spare parts, and after-sales service.
