The project is a high-end technology for the long-distance, large-capacity, economical and efficient transmission of electric energy from the Gongboxia Hydropower Station of the Northwest Power Grid and the 750 kV construction project from Qingting Guanting to Gansu Lanzhou. At present, it has applied for 6 patents, 17 utility model patents, and 2 design patents; 53 patents have been accepted. At the same time, 20 related technical standards were formed.
According to reports, the key technologies of the project are all completed by independent research and development, and the cost of technology introduction is about 130 million US dollars. The planned investment of the subsequent 750 kV project reached 63.9 billion yuan, all of which use domestically produced equipment, which will bring huge economic and social benefits to our power grid and equipment manufacturing industry.
