NARI-TECH(SH:600406) Sou Hu Cai Jing·2025-07-25 08:03Core Viewpoint - The article highlights China's significant advancements in ultra-high voltage (UHV) transmission technology, which has positioned the country as a global leader in the power sector, surpassing Western nations in both technology and influence [2][29]. Group 1: Historical Context - China's electricity industry began with reliance on imported American equipment, with the first electric light in Shanghai in 1882 [5]. - Initially, China's power generation ranked 21st globally, but the demand surged post-economic reforms, revealing structural challenges in energy distribution [5][10]. Group 2: Technological Development - The geographical and demographic disparities in China necessitated efficient power transmission solutions, leading to the development of UHV technology [7][10]. - UHV transmission lines can increase capacity by approximately five times and significantly reduce transmission losses over long distances, with effective ranges exceeding 2000 kilometers [8][10]. Group 3: Implementation and Achievements - The first UHV AC demonstration project was operational in 2009, marking a significant technological breakthrough [14]. - By 2023, China had constructed 40,000 kilometers of UHV lines, capable of transmitting over 2 trillion kilowatt-hours annually, equivalent to reducing coal transport by 600 million tons [16][18]. Group 4: Global Influence - China's UHV technology has become the world's largest and most advanced network, with comprehensive mastery over design, manufacturing, construction, and operation [18][19]. - The successful application of this technology has not only addressed domestic energy distribution challenges but has also gained international recognition, with projects in Brazil and the Philippines utilizing Chinese technology [27][29]. Group 5: Challenges and Future Prospects - Despite the success, the global promotion of UHV technology faces challenges, particularly in developed countries like the United States, due to complex geographical and regulatory environments [33][35]. - China's advancements in UHV technology provide a viable solution to global energy, environmental, and climate issues, contributing to a sustainable future [37][40].
