On October 27, 1958, the world's first 12,000 kilowatt, 3,000 rpm water-cooled double internally cooled turbine generator was born at the Shanghai Electric Machinery Factory.
In December of the same year, the Soviet Union organized a large-scale conference on turbogenerator cooling at the Leningrad “electricity” plant. In addition to the participation of major automobile manufacturers and research units of the Soviet Union, this meeting also included Wu Tianlin, deputy chief engineer of the Harbin Automobile Plant in Poland, Hungary and China, and Wang Geng of the Shanghai automobile factory. In accordance with the leaders' instructions, Wu Tianlin announced at the conference that China had produced a 12,000 kilowatt, 3,000 rpm double water-cooled turbine generator, which shocked the delegates present. Alexeiev, president of the Soviet Society of Electrical Engineering and Academyn of Soviet scientific communications, congratulated the Chinese representatives and mentioned at the meeting that China was the first to produce on trial a water-cooled twin turbine generator of 12,000 kW at 3,000 rpm /min using a 6,000 rpm motor. Rotary shaft kW. In Conference Proceedings and Proceedings. This is the first foreign report on China's first trial production of a water-cooled dual turbine generator.
