SIASUN(SZ:300024)2025-12-22 01:45Summary of Conference Call Notes Industry Overview - The conference call discusses the trends and developments in the power systems, humanoid robots, and industrial control sectors, highlighting the significant growth potential in these areas. Key Points on Power Systems - The power systems are transitioning towards high-voltage direct current (HVDC) technology, with rapid iterations in external power supply technology expected to lead to large-scale applications by 2028 [1][2]. - Domestic companies have a technological advantage in HVDC and solid-state transformers (SST), positioning them well in the market [1][2]. - The demand for transformers is strong due to long-cycle upgrades in the power grid, making them a critical component in the supply chain [1][6]. - Alibaba and Tencent have adopted HVDC technology, with the overseas market expected to initiate 800V projects by 2026, marking the arrival of the direct current era [1][7]. - The global investment in power grids is projected to grow at an annual rate of 5%, reaching a total capital expenditure of $650 billion by 2035 [1][18]. Key Points on Humanoid Robots - The humanoid robot market is expected to see production reach 20,000 to 30,000 units by 2025, with domestic demand accounting for about 20,000 units [1][2]. - 2026 is identified as a critical year for technology convergence and supplier confirmation, with Tesla planning to prepare for mass production by the end of 2026 [1][2]. - The supply chain for humanoid robots is rapidly expanding, with companies like Zhejiang Rongtai making significant progress in component integration [1][4][5]. - The market for humanoid robots is projected to exceed 10 billion yuan in orders by 2026, driven by strong policy support and commercial applications [1][27]. Key Points on Industrial Control - The industrial control sector is expected to recover starting in the second half of 2024, with significant contributions from the lithium battery industry and other OEM sectors [1][34]. - Domestic industrial control companies are actively exploring overseas markets, with companies like Inovance competing directly with Siemens [1][35]. - The focus on humanoid robots within the industrial control sector is increasing, with companies leveraging their technological advantages for future production phases [1][35]. Additional Insights - The global power grid construction faces bottlenecks, including supply chain issues, slow equipment expansion, and labor shortages, which may hinder rapid resolution of supply-side problems [1][17]. - The transformer market is experiencing a "super cycle," with demand driven by renewable energy and data centers, leading to a significant backlog of orders [1][19][20]. - The competitive landscape for power equipment companies shows that domestic firms like Siyuan are gaining market share, with room for valuation improvement compared to international counterparts [1][21]. Investment Recommendations - Recommended companies for investment include: - AIDC: Sunshine Sifang, Mai Mi, Zhongheng Hongfa, Liangxin - Humanoid Robots: Sanhua, Inovance, Rongtai, Keda Li, Weichuang, Zhenyu, Leisai, Beite, Sihong, Xinjie - Power Grid: Siyuan, Pinggao, XJ Electric, West Electric, Samsung, Haixing, Nanrui [1][36].
