Core Viewpoint - The A-share market experienced a significant downturn, but the high-voltage power transmission sector saw a remarkable surge due to three powerful driving forces: substantial investment plans, accelerated domestic substitution, and expanding overseas markets [1][3][5]. Investment Plans - The State Grid's "14th Five-Year Plan" outlines a fixed asset investment of 4 trillion yuan in the power grid sector over the next five years, representing a 40% increase from the previous period. Over 60% of this investment will be directed towards ultra-high voltage (UHV) and inter-regional transmission projects, translating to at least 2.4 trillion yuan flowing into the UHV and related industries [3][5]. Domestic Substitution - There is a clear policy directive to increase the domestic production rate of core UHV equipment from 90% to 98% by 2026, with procurement ratios for domestic equipment rising from 30% to over 50%. This shift is expected to redirect significant orders and profits from foreign manufacturers to domestic companies, benefiting leading firms in high-voltage switches, converters, and transformers [5][10]. Overseas Market Expansion - China's UHV technology is leading globally, with increasing demand for power grid upgrades and energy transitions worldwide. The "Belt and Road" initiative is facilitating the export of UHV technology, exemplified by successful projects like the Belo Monte UHV project in Brazil [6][7]. Market Performance - On February 2, the UHV sector saw a collective surge in stock prices, with companies like Electric Power Research Institute and Anke Intelligent Electric experiencing gains of 19.95% and 16.56%, respectively. Other companies in the sector also reported significant increases, with many stocks hitting their daily limit [2][10]. Industry Dynamics - The global market for large power transformers is currently facing a structural shortage, with a supply gap of 30%. The lead time for orders has extended from an average of 18 months in 2021 to over four years now, creating a favorable environment for Chinese companies with full industrial chain capabilities [7][10]. Order Growth - From the second half of 2025, several UHV equipment companies have reported significant year-on-year increases in contract amounts, indicating a strong order backlog that will support revenue growth in 2026 and 2027 [17]. Key Players - Major companies in the UHV sector include China Western Electric, which holds a dominant position in the market with over 40% share in core equipment like converters and GIS, and TBEA, recognized as a global leader in UHV transformers [15][16]. Investment Sentiment - Institutional investors, particularly social security funds, have heavily invested in key players like Anke Intelligent Electric and China Western Electric, indicating strong confidence in the sector's growth potential [10][14]. Conclusion - The convergence of substantial investment, domestic substitution policies, and international market opportunities is positioning the UHV sector for robust growth, attracting significant market interest and investment [1][3][5].
