[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 first batch of crude oil tank containers in the country were trial loaded and shipped]
• On September 2, 2026, a freight train carrying crude oil tank containers departed from Kuitun Station in Xinjiang and headed towards Jinling Town Station in Shandong, marking the completion of the first batch of crude oil tank containers in China's crude oil trial loading task and an important innovation in crude oil transportation mode. The crude oil tank container used this time is a standardized pressure vessel, which is transported in a closed manner throughout the entire process. The volatilization loss, measurement loss, and pollution risk of crude oil are synchronously reduced, which can better ensure the quantity and quality of oil products. Editor/Cheng Liting
