Core Downstream Channel for Low-Voltage Components: Analysis of the Key Market Role of Panel Builders
Panel builders serve as the core transformation node for low-voltage components moving from the brand side to end-user projects. Their component selection preferences, integration capabilities, and depth of customer coverage directly determine the market access efficiency and penetration level of low-voltage component brands in project implementation.
Medium- and low-voltage switchgear assemblers are a crucial link in the circulation process of the component market. Through the panel builder channel, they assemble components into complete switchgear products and sell them to end users. This model makes panel builders the primary circulation medium for components and the main customer base for component manufacturers. Therefore, panel builders occupy a core position in the component market and are a highly contested arena for all enterprises.
In terms of market size and competition, the market for medium- and low-voltage electrical switchgear assemblers in China is vast and highly competitive. In 2025, Daquan Group performed steadily in its main business of related products, with revenues exceeding 8 billion RMB (including the revenue of Zhenjiang Siemens), further consolidating its leading position in the industry. The competitiveness and market influence of some large-scale switchgear assemblers continue to strengthen, while small- and medium-sized panel builders face increasing pressure.
Distribution Characteristics of Medium- and Low-Voltage Switchgear Assemblers
The domestic panel builder market features a long-tail distribution with numerous small factories. However, the larger the enterprise, the stronger its ability to undertake high-value-added projects, as well as its profit levels, degree of intelligence, and influence on the selection of low-voltage component brands.
Currently, the number of panel builders nationwide is around 10,000 (with over 7,000 enterprises in low-voltage switchgear assembly). Small- and medium-sized panel builders account for over 80% of the total, while large panel builders account for less than 1%. However, the intelligence and technical levels of large panel builders are significantly higher than those of small- and medium-sized ones. Moreover, they have broader regional coverage and maintain close strategic partnerships with most leading industry clients.
Summary of the Survival Status of Panel Builders
Shifting from "competing on price and delivery" to "competing on engineering capabilities, customer structure, and cash flow management".
