The latter means an approach of self-supply of hydropower equipment. Based on the foundations laid through independent research and development, by way of digesting, absorbing and innovating the technologies introduced from abroad for the Left Bank Station of the Three Gorges Hydropower Station, domestic suppliers independently designed and manufactured large hydropower units for the Right Bank Station of the Three Gorges and many other large hydropower stations in China.展开更多
