Flash | Ans. Global top-tier transformer makers such as Hyundai Electric, Hitachi and Siemens have orders on hand to secure their earnings in 2026-28E. New orders should remain robust in 2026E amid rising capex from US utility, tech and data center companies. We expect LS Electric to receive new orders from the US datacenters of Amazon Web Services (AWS) soon given its strong track record in getting new orders from US datacenter entities. PRC transformer makers have seen strong growth from overseas (ex-US). ...

Core Insights - The overall judgment indicates that both domestic and overseas AI-driven demand will continue to grow, leading to stock price performance in the AIDC industry. The overseas market, particularly in the U.S., is experiencing tight supply and demand for power equipment, which presents opportunities for domestic supply chains to expand internationally. Additionally, domestic capital expenditure on power grids is steadily increasing [3]. AIDC Power Supply: Continuous Beta and Clear Industry Trends - The capital expenditure of major overseas cloud service providers (CSPs) is expected to continue increasing, driving high demand for AIDC. The total capital expenditure of the four major overseas CSPs (Amazon, Google, Microsoft, Meta) is projected to grow at rates of 34% in 2021, 20% in 2022, -7% in 2023, and 55% in 2024, with a significant increase of 71% in the first three quarters of 2025 [11]. - Domestic CSPs have also seen a resurgence in capital expenditure, with a staggering 184% year-on-year growth in 2024 and 87% in the first three quarters of 2025 [13]. - The power consumption of AI servers is expected to rise significantly, with cabinet power levels projected to exceed 200kW in the near future, indicating a need for technological upgrades in both internal and external power supplies [20][25]. - The transition from three-level to two-level voltage reduction in internal power supplies is anticipated, which will streamline power supply processes [28]. - External power supplies are shifting from UPS to HVDC and SST solutions, reflecting a clear trend towards direct current and medium voltage systems [32]. Power Equipment Export: Continuous High Demand - The U.S. has seen a rapid increase in new power installations since 2020, with growth rates of 1.20%, 2.42%, 0.98%, 2.14%, and 3.47% from 2020 to 2024, indicating a robust demand for power equipment [59]. - China's transformer exports reached 46.5 billion yuan in the first nine months of 2025, marking a 40.20% year-on-year increase, with other power equipment exports also showing significant growth [77]. Domestic Power Grid: Continued Investment and Recovery - The approval of ultra-high voltage direct current projects is progressing steadily, with a rich pipeline of projects expected to drive growth during the 14th Five-Year Plan [81]. - The total bidding amount for power grid projects has reached 78.7 billion yuan, reflecting a nearly 20% year-on-year increase, significantly surpassing the 7.61% growth rate of 2024 [84]. - The domestic smart meter replacement cycle is expected to smooth out, with a projected increase in bidding quantities in 2026-2027 as new standards are introduced [90].

数据显示，截至2025年11月28日，中证光伏产业指数(931151)前十大权重股分别为阳光电源(300274)、特变电工(600089)、隆基绿能(601012)、TCL科技 (000100)、通威股份(600438)、TCL中环(002129)、正泰电器(601877)、德业股份(605117)、阿特斯(688472)、晶澳科技(002459)，前十大权重股合计占比 61.01%。（以上所列股票仅为指数成份股，无特定推荐之意） 中国光伏产业链多环节下调12月份排产计划。在行业自律等因素影响下，硅料、硅片、组件等光伏产业链多个环节12月份排产环比下降。在业内看来，企业 持续减产也是光伏行业通过自律解决供需矛盾，落实"反内卷"的重要举措。多位业内人士认为，12月份光伏产业链多环节排产继11月份之后继续下降，也与 终端需求不足有关。随着"反内卷"效果显现，2026年光伏行业价格将逐渐回升。 截至2025年12月5日 11:08，中证光伏产业指数(931151)强势上涨1.62%，成分股罗博特科(300757)上涨10.35%，迈为股份(300751)上涨5.74%，科士达(002518) 上涨5.73%，阿特斯 ...
