Core Viewpoint - The completion and operation of the Hetian-Minfu-Qiemu-Ruoqiang 750 kV power transmission and transformation project marks the establishment of China's largest 750 kV ultra-high voltage ring network, significantly enhancing the power supply and renewable energy transmission capabilities in Xinjiang [1] Investment and Construction Details - The project involved a dynamic investment of 4.736 billion RMB, including the construction of two new 750 kV substations in Minfu and Qiemu, and the expansion of two existing substations in Hetian and Ruoqiang [1] - A total of 900 kilometers of 750 kV lines were built, making it the largest ultra-high voltage transmission project constructed in a single phase during Xinjiang's 14th Five-Year Plan [1] Engineering Challenges and Achievements - The project is part of the Xinjiang Tarim Basin 750 kV power transmission and transformation project, which consists of nine 750 kV projects completed in phases over a 15-year period, with a total ring length of 4,197 kilometers [1] - The construction faced various challenges, including working in desert, Gobi, mountainous, and river environments [1] Impact on Power Supply and Renewable Energy - The operation of the project ends the long-chain power supply pattern in southern Xinjiang, creating a hub-type backbone network that connects the north to the south and the west to the east [1] - The maximum power supply capacity is increased from 800,000 kW to 1,000,000 kW, and the renewable energy absorption capacity is enhanced by an additional 8 million kW [1] - This project not only improves the internal power supply but also strengthens the external transmission channels, significantly boosting Xinjiang's capacity to export green energy and facilitating the conversion of energy advantages into economic benefits [1]

沙漠奇迹：中国能源战略的闪耀答卷 今年四月，席卷西班牙、葡萄牙和法国南部的史无前例的大规模停电，将数百万民众推入黑暗。同一时刻，在中国，得益于塔克拉玛干沙漠——这片被称 为"死亡之海"的土地上的一项伟大工程，全国却实现了全年24小时电力供应的奇迹。这奇迹的缔造者，正是那条历时15年，投资逾百亿的750千伏超高压环 网工程。7月13日，这条总长4197公里的环网工程正式全线贯通，其意义远超工程本身，它标志着中国能源战略迈向了新的高度。 能源高速路：穿越死亡之海的挑战 环绕塔克拉玛干沙漠，覆盖面积达106万平方公里，相当于中国陆地面积的九分之一——这就是750千伏环网工程的宏伟规模。工程的难度超乎想象，特别是 和田至若羌段，900公里线路中450公里穿行于沙漠腹地，创造了全国沙漠线路长度的新纪录。 在流沙肆虐的沙漠中建设，挑战层出不穷。铁塔刚刚矗立，翌日便可能被流沙掩埋大半。建设者们攻克难关，发明了螺旋锚基础技术，如同为铁塔穿上 了"防滑鞋"，牢牢抓住不稳定地基。他们还采用了"三快"施工法——快速组塔、快速架线、快速调试，最大限度地压缩施工周期，减少恶劣环境的影响。 而真正的宝藏，则埋藏在地下。塔克拉玛干沙漠是名 ...
