Core Viewpoint - The market demand for box-type substations is primarily driven by the State Grid Corporation of China, which is a major user of distribution equipment and plays a leading role in the construction of smart grids and new power systems in China. The total tender volume for box-type substations is expected to reach 14,078 units in 2024, reflecting a year-on-year growth of 1.85% [1][13]. Overview - Box-type substations integrate high-voltage ring network cabinets, transformers, low-voltage switches, and other systems into a sealed, moisture-proof, and rust-proof double-layer box, making them suitable for outdoor use in power distribution systems. They are characterized by high automation, lightweight, easy installation and maintenance, and short construction periods, making them widely used in various power consumption scenarios [2][4]. Market Policy - The box-type substation industry is classified under "C38 Electrical Machinery and Equipment Manufacturing" in China's national economic industry classification. The development of this industry is supported by various policies aimed at enhancing the safety and efficiency of the power system, including guidelines for rural power grid enhancement and promoting intelligent manufacturing in the power equipment sector [7][9]. Industry Chain - The upstream of the box-type substation industry includes suppliers of metals like steel and aluminum, as well as insulation materials and electrical components. The midstream consists of manufacturing companies responsible for the design, production, assembly, and testing of substations. The downstream market encompasses various applications, including power grids, infrastructure construction, electric vehicle charging stations, and renewable energy projects [10][12]. Development Status - The State Grid Corporation's procurement of box-type substations is influenced by external macroeconomic conditions, industrial policies, and project schedules. The tender volume has shown fluctuations from 2017 to 2024 but has generally maintained an upward trend. The demand for box-type substations is expected to rise due to urbanization, infrastructure projects, and the growth of renewable energy and electric vehicle charging stations [12][13]. Competitive Landscape - The box-type substation market in China is fragmented, with numerous participants. In 2024, 125 companies won tenders from the State Grid, with Shanghai Zhixin Electric leading with a bid amount of 233.83 million yuan, followed by Beijing Haocreat Electric and Ningbo Aokex Intelligent Technology [15][17]. Industry Representative Companies - Mingyang Electric: Focuses on renewable energy and new infrastructure, with a revenue of 6.444 billion yuan in 2024, of which 4.239 billion yuan (65.78%) comes from box-type substations [25]. - Qingdao Teruid Electric: Engages in smart manufacturing of box-type substations, achieving a revenue of 15.37 billion yuan in 2024, with 4.388 billion yuan (28.55%) from box-type equipment [27]. Development Trends - Future advancements in box-type substations will leverage IoT, big data, and AI technologies for enhanced monitoring, control, and protection capabilities. There will be a focus on energy efficiency and environmental considerations in materials and manufacturing processes, aiming to reduce energy loss and environmental impact [29].
