On May 28th, the foundation of Ningxia section of 201116, Hami South-Zhengzhou 800 kV DC transmission line project began to be poured in Guanqiao Township, Haiyuan County, which marked that the Ningxia section of the project officially entered the field construction stage.
20 13, 16 On April 6th, Hami South-Zhengzhou 800 kV UHV power transmission and transformation project successfully crossed the Yellow River, and all blocks were completed. It is understood that the world's longest UHV transmission project will be completed in 20 13 years, and it will provide more than 40 billion kwh of electricity for Henan every year after being electrified.
2065438+June 6, 2003, with the ±800kV high-voltage transmission line from Hami South to Zhengzhou erected outside Hami Converter Station 1 Tower, the transmission line project of Xinjiang section with a total length of 165.553 km was completed, 24 days ahead of the planned completion at the end of June, making it the first province along the whole line to realize the whole line connection.
2065438+On June 7th, 2003, the track laying of Gan 1 full-length106km was successful, which played an exemplary role for the whole project.

2065438+200465438+1In the early morning of October 25th, the Hami South-Zhengzhou 800 kV DC project successfully passed the 168-hour trial operation test, which indicated that the project was fully completed and had formal commercial operation conditions.
The Harbin-Zhengzhou UHV project directly boosted Xinjiang's investment by 654.38+0.8 billion yuan. As the "Power Silk Road" connecting the western frontier and the Central Plains, it can transmit 50 billion kWh of electricity to Central China every year, which is equivalent to transporting 23 million tons of coal, reducing emissions of 40 million tons of carbon dioxide and 330,000 tons of sulfur dioxide.
From April 6, 2065438 to April 20, 2005, Harbin-Zhengzhou DC project (Xinjiang section) successfully passed the quality evaluation, green construction demonstration project and new technology application demonstration project acceptance.
