国网白银供电公司：陇东直流配套330千伏输电工程完成初检验收

Core Viewpoint - The initial acceptance inspection of the 330 kV transmission lines in the Longdong DC Baiyin supporting project has been successfully completed, laying a solid foundation for the "zero defect" operation of the lines [2][5]. Group 1: Project Overview - The acceptance inspection involved four newly constructed 330 kV lines, totaling 196.6 kilometers in length and comprising 481 physical towers [2]. - The project traverses 12 towns in Baiyin District, Pingchuan District, Jingtai County, Jingyuan County, and Lanzhou New District [2]. Group 2: Inspection Process - The inspection began in late August and was conducted in conjunction with the construction progress, adhering to standardized, professional, and refined guidelines [3]. - A comprehensive "health check" was performed on the line's tower structures, grounding wires, environmental conditions, and auxiliary facilities [3]. Group 3: Challenges and Team Efforts - The inspection team faced challenges such as complex mountainous terrain and variable weather, with over 20 personnel demonstrating resilience and dedication to complete the task on time and with high quality [5]. - Any issues identified during the inspection were documented and promptly communicated to the construction unit for rectification, ensuring a closed-loop management process [5]. Group 4: Project Impact - The completion of the initial acceptance inspection marks the transition to the defect rectification phase, with the project soon meeting operational conditions [5]. - The connectivity of the Longdong DC Baiyin segment is expected to optimize the regional grid structure and enhance the reliability of power supply, serving as a strong "power engine" for local economic and social development [5].
