By the early 1970s, major generator production centers in Harbin, Liaoning Province, Shanghai, Beijing, and Deyang, Sichuan Province, had built both hydro and thermal generators as large as 300 megawatts. There also were numerous small and medium-sized plants producing generators in the 3.2 to 80-mÍÍÍÍegawatt range. As of 1986, China manufactured condenser-type turbo-generating units with capacities of 6,000 to 300,000 kilowatts back-pressure extraction generating units with capacities of 12,000 to 50,000 kilowatts, geothermal facilities with capacities of 1,000 to 3,000 kilowatts and hydropower equipment consisting of generator equipment with an 18-million-kilowatt capacity. Deficiencies showed in powergenerating equipment and transmission technology, and significant problems existed in direct-current transmission, particularly in converter technology. China continued to lack experience in design and production of high-volt-ampere transformers and circuit breakers.
