Recently, in the Huangshayang sea area of Rudong, Jiangsu, Shanghai Yuanwei Construction Engineering Co., Ltd. (referred to as "Shanghai Yuanwei"), a subsidiary of Zhongtian Technology Group, successfully completed the construction of over 20 kilometers of exposed submarine cables and buried them, providing core equipment and independent technology to safeguard the safe operation of Asia's first flexible DC submarine cable transmission offshore wind power project.
On April 7th, the deepest offshore wind power project in China, the Huaneng Shandong Peninsula North L site offshore wind power project, achieved full capacity grid connected power generation, marking a new breakthrough in China's offshore wind power in the complex environment of the deep sea and the integration of large capacity units.
In April, China's ultra-high voltage power grid construction entered a period of intensive breakthroughs, with new progress reported in seven key projects from the eastern coastal areas to the western inland areas, with a total investment of over 200 billion yuan, outlining a green power grid that covers the whole country and is interconnected across regions.
Recently, a "underwater giant dragon" weighing 13700 tons and with a total length of over 180 kilometers sank steadily to the bottom of the sea in Yangjiang, Guangdong. The Three Gorges Yangjiang Qingzhou Five and Qingzhou Seven Sea Wind Farm Submarine Cable Concentrated Transmission Project, constructed by China Energy Engineering Guangdong Institute through EPC general contracting, has successfully completed the laying of the world's highest voltage level, largest transmission capacity, and largest conductor cross-section cross-linked polyethylene DC submarine cable.
