中国攻破“卡脖子”技术！电力心脏不再受制于人，东电再立新功！

Core Viewpoint - China has achieved a significant breakthrough in the power sector by independently developing key technologies that were previously reliant on foreign imports, particularly in high-end power equipment such as transformers and large generator sets [1][3][5]. Group 1: Technological Breakthrough - The term "bottleneck" refers to critical technologies that China could not produce domestically and had to import, leading to vulnerabilities in the power supply [3]. - The successful development of a domestically produced 1 million kilowatt nuclear power main unit technology by Dongfang Electric Group marks a significant milestone, previously dependent on suppliers from the US and Japan [5]. - This achievement has resulted in hundreds of patents and has filled a technological gap in the domestic market [5][6]. Group 2: Economic Impact - The shift to domestic production is expected to save millions of dollars previously spent on imports, allowing funds to be redirected towards other technological research and development [6]. - The self-sufficiency in power equipment has increased from 60% five years ago to over 85% currently, indicating a substantial improvement in domestic capabilities [7]. Group 3: National Security and International Standing - The independence in power equipment production enhances national security by reducing reliance on foreign suppliers, which could disrupt power supply during international tensions [5][6]. - China's international standing has improved, transitioning from a "follower" to a "leader" in high-end manufacturing, with Dongfang Electric's products being exported to countries involved in the Belt and Road Initiative [6][9]. Group 4: Future Directions - The next goal for Dongfang Electric's research team is to develop energy storage technologies to maximize the use of renewable energy sources like wind and solar [9]. - The overall message emphasizes that self-reliance and innovation are crucial for future success in the power sector [9].
