[The world's first 500 kV economical high voltage AC current limiter] A few days ago, the world's first 500kV/90kA economical high-voltage AC current limiter developed by China Xidian Group successfully completed the manual short-circuit test and was successfully put into operation on the Shun-Guang-A line of the 500kV Guangnan Station. The successful operation of the project has filled the domestic economical AC ultra-large short-circuit current suppression technology gap, provided an economical and reliable solution for the suppression of high-voltage AC short-circuit current, and provided a strong guarantee for the reliable operation of the ultra-high-voltage large power grid.

• [The prosperity of semiconductor equipment is on the rise]
• The semiconductor equipment sector of A-shares strengthened in the short term during trading, with silicon power stocks rising by over 10%, and multiple targets synchronously rising. In the first quarter of 2026, global semiconductor equipment sales reached a historic high of 36.55 billion US dollars. Domestic wafer production lines continued to expand, coupled with the improvement of the industry standard system. Domestic equipment in multiple process links was imported in bulk, and upstream precision components and advanced packaging and testing industries were simultaneously driven by demand.
