August 20, 2025 – The Ningxia-Hunan UHV Project, China’s first ultra-high voltage transmission line connecting the "Shagehuang" wind and solar base, was officially completed and put into full operation with a capacity of 8 million kilowatts. The successful delivery of clean energy from the "Shagehuang" region to Hunan Province is largely attributed to the high-end converter transformers independently developed by TBEA, which have solved the global challenge of "difficulty in transmitting renewable energy from resource-rich areas to load centers."

The "Shagehuang" region features complex geographical conditions—high temperatures, sandstorms, and large temperature differences between day and night—posing severe challenges to the reliability and adaptability of power equipment. The custom-made high-end converter transformers provided by TBEA can withstand extreme environments while achieving efficient power conversion and stable transmission, effectively solving the pain point of renewable energy being "generated but not transmitted"—a problem also faced by renewable energy bases in the western United States and the Middle East.

It is reported that the Ningxia-Hunan UHV Project can transmit more than 40 billion kWh of clean electricity annually, equivalent to replacing 12 million tons of raw coal and reducing carbon emissions by 26 million tons. The core indicators of TBEA’s converter transformers, such as insulation and temperature rise, far exceed international standards, ensuring the efficient and stable transmission of clean energy. Industry insiders said that this transformer technology breakthrough not only promotes the development of new energy in the "Shagehuang" region but also provides a replicable solution for global renewable energy delivery, helping countries overcome the bottleneck of outdated power infrastructure.
