In March 2026, Shanghai Chengjiang Energy Conservation and Environmental Protection Technology Co., Ltd. (hereinafter referred to as "Chengjiang Technology") announced a major achievement: the electrical cabinet supporting the exhaust gas system that the company built for the Zhongrun US photovoltaic cell factory project successfully passed the stringent audit of Intertek, a globally recognized authoritative testing and certification organization, and officially obtained UL508A standard certification. This certification signifies that Chengjiang Technology's electrical cabinet products have met the highest safety standards of the North American market in terms of design, manufacturing, and quality, successfully obtaining a "passport" to enter the North American photovoltaic industry market.
UL508A, as the most authoritative core safety standard in the North American industrial control cabinet field, imposes extremely stringent requirements on all aspects of electrical cabinet design, electrical component selection, production processes, and manufacturing procedures. It not only focuses on the compliance of individual components but also emphasizes the integrated safety and system compatibility of the entire system, making it a mandatory entry threshold for industrial control equipment in the North American market. The photovoltaic exhaust gas system electrical cabinet certified by Chengjiang Technology has undergone comprehensive audit and verification by Intertek China, perfectly meeting the UL508A standard specifications in key indicators such as electrical clearance, wiring standards, and short-circuit current intensity. It also meets all relevant US standards for electrical cabinets, fully demonstrating the product's superior quality and technical strength.
As a company specializing in the R&D and manufacturing of electrical systems for energy-saving and environmentally friendly equipment, Chengjiang Technology consistently adheres to high international standards in product development. Deeply rooted in the photovoltaic industry's supporting equipment sector, the company provides safe, reliable, and efficient electrical cabinet solutions for various industrial projects through its pursuit of technological excellence and strict quality control. The successful certification of the electrical cabinet for the exhaust system of the Zhongrun US photovoltaic cell factory project marks a significant milestone in Chengjiang Technology's international product strategy. It not only demonstrates the company's comprehensive capabilities in electrical cabinet design and manufacturing but also highlights the technological competitiveness of Chinese photovoltaic supporting equipment companies in the international market.
Currently, the North American photovoltaic industry is experiencing new development opportunities, with market demand for high-quality, compliant supporting equipment continuing to rise. The acquisition of UL508A certification lays a solid compliance foundation for Chengjiang Technology to expand into the North American photovoltaic market. Moving forward, the company will leverage this opportunity to continuously deepen technological innovation and quality upgrades, constantly improve its international product system, and provide global photovoltaic industry customers with better electrical supporting solutions, helping Chinese photovoltaic equipment reach the world stage.
