[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.

In 2026, Tanzania's new mining policy officially came into effect, requiring that 20 key mining materials must be provided by local enterprises. The authorities have launched the construction of 21 manufacturing factories at the abandoned Buz Waji gold mine site, gradually replacing imports. This measure forces international suppliers to change their original pure export model, and Chinese enterprises need to turn to local production and supply through technology joint ventures and other means to cope with supply chain restructuring.Editor/Gao Xue
In 2026, Tianjin Xinhecheng High end Chemical New Materials Project made key progress. The project is located in Nangang Industrial Zone, with a total investment of about 10 billion yuan, and will construct a full industry chain production line for adiponitrile, hexamethylenediamine, and nylon 66. At present, the first phase of the project's above ground engineering has obtained construction permits and is ready for full commencement. It is expected to be completed and put into operation in 2027, and the products will be widely used in fields such as automobiles and new energy.Editor/Gao Xue
