【中泰电新】750亿美元扩建超高压电网，北美缺电持续演绎 据TheInformation报道，过去数月内，美国三大区域电网运营商（得克萨斯州、中大西洋地区和中西部电网管理部 门）相继获批了总计750亿美元的输电扩容项目，核心是建设一批765千伏超高压线路–这是美国当前最高运行电压 等级，输电能力可达传统线路的六倍。 另外，北美本土企业产能已告急。 目前全美唯一具备765千 目前全美唯一具备765千伏变压器生产能力的企业是位于田纳西州孟菲斯的晓星HICO工厂。 该厂上月斩获5.41亿美元设备订单，并启动2.08亿美元产能扩建，员工数量将增至800多人。 但HICO美国公司负责人坦言：#"未来两年的产能已几乎全部排满……我们无法满足所有需求。 " 如此大规模的电网建设计划可能导致原本就紧张的变压器等电力设备环节产能进一步短缺，北美缺电逻辑有望得 到中长期演绎，重点关注确定性进入北美电力设备市场标的：思源电气、金盘电气、伊戈尔、宏远股份、神马电 力、安靠智电、三星医疗、大连电瓷等。 美国大规模建设虹吸全球供应链利好国内电力设备出海，重点关注特锐德、特变电工、平高电气、四方股份、华 明装备、中国西电等。 风险提示：需 ...

Core Viewpoint - The successful operation of the Aral 750 kV substation and the commissioning of the Kuqa-Aral-Bachu 750 kV power transmission project mark the completion of the last ultra-high voltage ring network project in Xinjiang, providing strong electrical support for high-quality economic development and winter peak demand in southern Xinjiang [1][3]. Investment and Infrastructure - The total investment for the Kuqa-Aral-Bachu 750 kV power transmission project is 3.04 billion yuan, starting from the Kuqa 750 kV substation and ending at the Bachu 750 kV substation, with a total line length exceeding 485 kilometers [3]. - The Aral ring network consists of three 750 kV power transmission projects, covering four substations and a total line length of 1,458 kilometers, enhancing the power interconnection capacity between southern and northern Xinjiang by 400,000 to 500,000 kW [3][5]. Development Progress - Since 2010, the State Grid Xinjiang Electric Power has significantly increased the construction of the southern Xinjiang power grid, completing 10 lines of 750 kV projects over 15 years, which has greatly released the resource potential of southern Xinjiang [5]. - The construction of the Kuqa-Aral-Bachu 750 kV power transmission project has overcome challenges in desert saline-alkali land and minimized impacts on agricultural production while focusing on ecological protection [5][8]. Network Expansion - Since the 14th Five-Year Plan, the pace of ultra-high voltage power grid construction in Xinjiang has accelerated, with 17 new 750 kV substations and a total line length of 7,266.7 kilometers added, achieving a historic transition from a "four-ring network" to a "seven-ring network" [8]. - Xinjiang has established a main grid structure of "seven internal supply rings and five external delivery channels," extending 3,300 kilometers north-south and 2,200 kilometers east-west, covering an area of approximately 1.6 million square kilometers [8].
