Recently, China's State-owned Assets Supervision Commission issued the latest news: China's development of 1000KV uHV circuit fittings through acceptance, this achievement proves that China's production of 1000KV power fittings has reached the international top level.

This time, the actual development of 1000KV UHV circuit fittings is mainly aimed at the development of team separation spacer bar. The multi-separation spacer bar developed and produced by China has completely reached the use standard of UHV line in various performance tests, and has carried out strict testing and testing on the basis of international power fittings standard. Whether in mechanical or electrical properties, the research and development of multipartition spacer has achieved great success.

At the same time, the research and development of uHV line draping string, tensioned string and other power fittings has made great achievements, so the production level of China's UHV power fittings has been synchronized with the world's powerful countries of the same level and reached the top of the world's first-class industry.

In this research and development process, the successful research and development of 8-split wire damping spacer made of aluminum alloy is the first in the world. In the technology of 8-split wire damping spacer made of aluminum alloy, China's power industry has reached the international leading level. It is worth mentioning that the combined shielding technology of open pressure equalizing ring and metal fittings developed by China has also passed the test of The State Quality Supervision Commission and passed the test of the industry standard in terms of electrical performance, which has played a great role in promoting the progress of China's power grid technology.

It is believed that during the 12th Five-Year Plan period, China's power grid construction will focus on the construction of uHV circuits above 500KV. The release of this achievement promotes the pace of China's high-tech UHV power grid construction and lays a stable foundation for the construction of China's 1000KV power grid demonstration project.
