四川阿坝——成都东特高压工程首个标段贯通

Core Viewpoint - The Sichuan Aba-Chengdu East 1000 kV UHVAC transmission project has successfully completed its first segment, marking a significant milestone in the construction of a major clean energy transmission line in Sichuan province [1][6]. Group 1: Project Overview - The project spans a total length of 734.8 kilometers, connecting the Aba 1000 kV substation to the Chengdu East 1000 kV substation, and traverses four cities and eleven counties [6]. - The first segment, which has been completed, is approximately 85 kilometers long, starting from Mianyang Santai County and ending in Deyang Zhongjiang County, requiring the construction of 176 new transmission towers [3][6]. Group 2: Construction Progress - Currently, over 3,000 builders are engaged in the construction across 16 segments, with a completion rate of nearly 90% for tower assembly and over 40% for wire installation [4][6]. - The project employs advanced technologies such as construction safety networks and visual tensioning equipment to ensure efficient and safe progress amid challenging geological and climatic conditions [3][4]. Group 3: Strategic Importance - The project is positioned as a core carrier for the high-quality development of clean energy in western Sichuan, with an expected operational date by the end of 2026 [6]. - Once operational, the transmission capacity of the Aba corridor will more than double, effectively meeting the grid connection needs of the Aba hydropower cluster and renewable energy bases, ensuring stable delivery of clean electricity to load centers like Chengdu [6].
