The 6250A UHVDC converter valve fills a number of international gaps

It is understood that UHVDC transmission is a major technology
to meet China's ultra-large capacity and ultra-long-distance transmission and implement the strategy of west-to-east power transmission.
Converter valve equipment is the core component
of UHVDC transmission projects.

With the support of a number of project funds such as the science and technology projects of the State Grid Corporation of China and the major scientific research projects of Xuji Group, through the exploration and research of the key technologies of UHVDC transmission converter valve equipment, Xuji Group has successfully developed 6250A UHVDC transmission converter valve equipment, mastered the core technology, formed independent intellectual property rights, and met the strategic needs
of the rapid development of China's power technology and construction.

At present, the rated voltage of UHV converter valves operating in China is ±800kV and the rated current is 5000A
.
The DC project with the highest voltage level abroad is India± 800kV, 3750A UHVDC transmission project
.
The transmission capacity of 6250A UHVDC converter valve is increased by 25% compared with ± 800kV/5000A converter valve, which further improves the conveying efficiency and greatly saves costs, which is the largest flow capacity of similar products in the world and is the first development in the
world.
