Core Viewpoint - The successful completion and operation of the 750 kV line project from Shapotou to Zhongning marks a significant milestone in the Ningxia to Hunan ±800 kV UHVDC transmission project, which is crucial for the country's energy development strategy [1][3]. Group 1: Project Overview - The Ningxia to Hunan ±800 kV UHVDC project is China's first high-voltage transmission line primarily designed to transport electricity from renewable energy bases located in desert and arid regions [3]. - The Shapotou to Zhongning converter station's 750 kV line is a key component that ensures the smooth commissioning of the converter station's AC system and serves as a core power transmission channel for future DC low-end power delivery [3]. Group 2: Construction Details - The construction of the Shapotou to Zhongning 750 kV line began on June 5, 2024, with a total length of 46.98 kilometers and the erection of 68 new towers, utilizing a mixed single and double circuit setup [5]. - The NG18 tower, reaching a height of 155.9 meters, set a new record for tower height in Ningxia's power construction history [5]. Group 3: Environmental and Operational Considerations - The project adheres to green construction principles, implementing environmental protection measures alongside construction to ensure ecological restoration, particularly in the fragile ecosystem at the edge of the Tengger Desert [5]. - The company plans to increase resource investment and enhance professional collaboration to expedite the construction of critical supporting projects, ensuring the timely operation of the Ningxia to Hunan ±800 kV UHVDC project [5].
