On September 27, 2024, the ± 800 kV high-voltage direct current transmission project from Jinshang to Hubei in the western part of Chongqing was successfully completed. Behind this feat, Yongfu Co., Ltd. undertook the key survey and design tasks. As a key power transmission and transformation project in the 14th Five Year Plan of the country, the Jinshang Ultra High Voltage Project is renowned for its ultra-high altitude. The Yuxi section of the project passes through the Tongnan, Tongliang, and Hechuan districts of Chongqing, with a newly laid ultra-high voltage direct current line of approximately 91.883 kilometers.
The construction environment in the western part of Chongqing is extremely complex, with variable geological conditions and facing many challenges in crossing operations. The power grid design team of Yongfu Co., Ltd. actively responded to the construction policy of "Six Refinements and Four Modernizations", and successfully overcame multiple difficulties in the project with its refined ultra-high voltage survey and design plan. Considering the numerous environmentally sensitive points along the project route, such as urban planning areas, wetland parks, nature reserves, etc., the Yongfu team has significantly reduced the potential impact of the project on the environment along the route by carefully optimizing the path design. At the same time, the team strictly followed the three crossing technical standards and implemented differentiated design for ultra-high voltage transmission lines, successfully crossing multiple important transportation lines and ultra-high voltage lines including Tongrong Expressway, Yushui Expressway, and Shanghai Chengdu High speed Railway.
Building the Dream of National Strength Together with Ultra High Voltage Energy Sichuan Road as the Foundation! Yongfu Corporation has demonstrated outstanding strength in the Jinshang Ultra High Voltage Project, bravely climbing the world's peaks and making important contributions to building a strong power grid artery. At the same time, it has also presented a generous gift for the 75th anniversary of the founding of the motherland. In the future, Yongfu Co., Ltd. will continue to adhere to the design concept of craftsmanship and quality, closely focus on customer needs, constantly explore and innovate, and continue to write brilliant achievements in the great journey of ultra-high voltage construction, contributing more wisdom and strength to the global energy transformation.Editor/Cheng Liting
