[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 European Union has announced its 2040 high-speed rail development plan, with a total investment of 550 billion euros, aiming to build a high-speed rail network across Europe and reduce travel time between major capitals by half. The funding will adopt the "EU Fund+Member State Supporting+Private Capital" model, and a high-speed railway agreement will be introduced before 2026 to leverage private capital. The entire network will unify the signal system, with a focus on filling the gaps in Eastern and Southern Europe. This website has the triple intention of green transformation, economic cohesion, and geopolitical strategy, but financing, land acquisition, and approval are still tough battles, and whether they can be realized depends on the finances and progress of each country.Editor/Cheng Liting
