Development of PV Power Stations As a core component for fixing photovoltaic modules, photovoltaic mid clamps play a critical role in solar installations. Relying on years of experience in R&D and manufacturing of fasteners, Zhongtang Group has become a high-quality supplier in the field of PV bracket accessories, providing stable and reliable module connection solutions for solar power stations worldwide. Located in Yongnian Fastener Industrial Base, Handan, Hebei Province, Handan Zhongtang Fastener Manufacturing Co., Ltd. specializes in the R&D, production and sales of PV brackets and accessories, with PV mid clamps as one of the group’s core competitive products. The company adopts high-strength aluminum alloy materials including 6063-T5 and 6005-T5, processed through precision extrusion and anodizing surface treatment. The products feature light weight, high strength, corrosion resistance and aging resistance, capable of adapting to extreme temperature differences from -40°C to 80°C, coastal salt spray, strong ultraviolet radiation on plateaus and other complex environments. With a service life of over 25 years, they perfectly match the full life cycle of PV modules. Zhongtang Group offers a complete range of PV mid clamps, covering mainstream lengths of 40mm, 50mm, 60mm, 80mm and more, suitable for various PV module frames with thicknesses from 1.4mm to 4mm. Customized production is supported to meet diversified application scenarios such as ground-mounted power stations, rooftop distributed PV, floating PV and agrivoltaic systems. Featuring an optimized mechanical structure design, the products are equipped with anti-slip teeth and self-locking slots to evenly distribute stress on modules, effectively resisting natural disasters such as typhoons and blizzards, and eliminating hidden dangers such as module cracking, loosening and displacement. Compared with traditional clamps, Zhongtang’s new products improve installation efficiency by 40%, enabling one-hand quick fastening and significantly reducing construction labor costs. In recent years, with the popularization of large-size, high-power PV modules in the solar industry, Zhongtang Group has continued technological upgrading and launched ultra-thin and high-toughness PV mid clamps. While ensuring strength, the products reduce self-weight by 15%, adapting to 210mm and 182mm large-size modules and enhancing the overall load capacity of power stations. At present, the group’s annual production capacity of PV mid clamps exceeds 50 million pieces. The products not only supply large-scale power station projects of major domestic enterprises such as Huaneng and State Power Investment Corporation, but also are exported to more than 30 countries and regions including Europe, Southeast Asia, Central Asia and South America. Certified by the ISO9001 quality management system, the products have won unanimous recognition from customers at home and abroad. As a leading local PV accessories enterprise in Hebei Province, Zhongtang Group will continue to deepen technological innovation in PV mid clamps, integrate new materials and intelligent design, and create more efficient, stable and cost-effective PV fixing solutions. The group is committed to supporting the high-quality development of the global new energy industry and making solid contributions to achieving the "Dual Carbon" goals.
