[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 Zhongke Aerospace Power Arrow 1 successfully launched an eight star rocket]
• On April 14, 2026, the Zhongke Aerospace Lijian-1 Y12 rocket successfully launched "One Rocket, Eight Stars" from the Dongfeng Commercial Aerospace Innovation Experimental Zone. This mission adopts the "special vehicle" launch mode, compressing the contract to launch cycle to 6 months, marking the official entry of China's commercial aerospace into the era of "flight based" mass production. Relying on a pulsating production line, the rocket assembly cycle has been reduced to 30 days, and the future annual production will reach 30 missiles. Editor/Cheng Liting
