美苏日全折戟，中国却做到了！想学这一招？全球标准都由中国定！

Core Viewpoint - The U.S. Energy Secretary's statement expressing a desire to learn from China's ultra-high voltage (UHV) transmission technology highlights a significant shift in perspective, indicating that the U.S. recognizes China's leadership in this field [1]. Group 1: Historical Context and Challenges - The U.S. faced a major power crisis during a severe winter storm in Texas in 2021, leading to widespread outages and highlighting the limitations of its electrical grid system [5][7]. - The U.S. electrical grid is divided into three independent systems, which lack interconnectivity, making it difficult to provide mutual support during crises [7]. - Previous attempts by the U.S., Soviet Union, and Japan to develop UHV technology failed due to technical challenges, particularly in insulation materials [10][8]. Group 2: China's Breakthrough in UHV Technology - In 2005, China decided to pursue UHV technology to address its energy distribution challenges, which involved significant investment and overcoming skepticism about the technology's feasibility [11][15]. - The Chinese team developed lightweight insulation materials that significantly reduced the weight of transformers, facilitating transportation and implementation of UHV systems [16]. - By 2025, China had constructed 45 UHV projects, providing power to approximately 900 million people and significantly reducing coal consumption and emissions [16]. Group 3: Global Impact and Future Prospects - China is now promoting a global energy internet concept, expanding its UHV technology to 47 countries, which could lead to a more interconnected global power grid [17]. - The success of China's UHV technology not only positions it as a leader in the field but also allows it to set global standards for power systems [16][17].
