[Micro Video] my country's first 330 kV "Liu Tianguan" transmission line in 50 years has been put into operation for 50 years to transport a total of 74 billion kilowatt -hours

my country ’s first ultra-high voltage transmission line 330 kV Liujiaxia-Tianshui-Guanzhong’ s transmission line is safely launched for 50 years, with a cumulative transportation electricity volume of 74 billion kilowatt-hours, which has continued to contribute to the economic and social development of the Northwest region.

The "Liu Tianguan" transmission line is the first 330 kV ultra -high -voltage transmission project designed, constructed, and built in my country. The line starts its own provincial Liujiaxia Hydropower Station. , Crossing 14 counties and districts in the two provinces of Ganshan, 534 kilometers in length, and a design conveying capacity of 420,000 kilowatts.

The "Liu Tianguan" transmission line was the most transmission distance in my country at that time, the highest voltage level, and the largest transmission power transmission and transmission project, and realized the upgrade leap from 220 kV to 330 kV. At present, the historical mission of 330 kV transmission line across provincial power delivery has been gradually replaced by the 750 kV transmission line.

Although the "Liu Tianguan" transmission line is no longer the original, the old line still plays a new role, providing electricity guarantee for important loads such as Baolanke's electrified railway, and continuously providing strong power support for local economic development.
