中老500千伏联网工程输电线路全线贯通

Core Viewpoint - The successful high-altitude connection of the transmission line at the border between Yunnan, China, and Laos marks the physical connectivity of the China-Laos 500 kV interconnection project, symbolizing a significant achievement in energy cooperation between the two countries [1] Group 1: Project Overview - The total length of the China-Laos 500 kV interconnection project is 177.5 kilometers, with the Chinese section measuring 145 kilometers and the Laotian section 32.5 kilometers [1] - The project is jointly invested and constructed by China Southern Power Grid Company and the Laos National Transmission Company [1] - Upon operation, the project is expected to have a bi-directional power transmission capacity of 1.5 million kilowatts and deliver approximately 30 billion kilowatt-hours of clean electricity annually [1] Group 2: Environmental Protection Measures - A series of refined control measures were implemented to protect the ecological environment and biodiversity along the route [1] - The construction and path optimization reduced the line length by 6 kilometers, decreased the number of cableway installations by 15, and minimized temporary land occupation by over 80,000 square meters [1] - The amount of timber felled was reduced by over 83%, allowing for the preservation of more than 30,000 trees, and construction disturbances in nature reserves were reduced by over 90% [1] Group 3: Strategic Significance - The China-Laos 500 kV interconnection project is a landmark achievement in deepening practical cooperation and building the "Belt and Road" initiative, extending "hard connectivity" from transportation to the energy sector [1] - This project will enhance regional infrastructure connectivity and promote the optimization of energy structures and clean development [1]
