The global construction of new power systems has accelerated steadily in 2026, with large-scale expansion of ultra-high voltage transmission, cross-border grid interconnection, and renovation of aging distribution networks driving comprehensive upgrading of the power fitting industry. As a core hinged connection component for overhead transmission lines, the UB-10 clevis hinge has become a standard essential fitting for new construction and renovation projects worldwide, thanks to its flexible rotating structure, stable 100kN rated load capacity, and outstanding all-weather environmental adaptability. Export orders continue to grow steadily, effectively boosting the overseas trade performance of China's power hardware industry.
According to the latest data released by the China Electricity Council, the domestic power fitting market maintains a year-on-year growth rate of 7% to 9% in 2026. Standardized forged power fittings suitable for medium and high-voltage transmission lines witness particularly strong export demand, with prominent order increases from Southeast Asia, the Middle East, Africa, and other emerging infrastructure markets. Compared with traditional fixed-angle hanging plates, the UB-10 clevis hinge effectively solves common technical pain points in overhead line construction, including angular misalignment, local stress concentration, and long-term vibration fatigue. It perfectly adapts to complex construction scenarios such as terrain fluctuation, jumper transition connection, and tower installation deviation, making it a preferred product for international EPC power projects and global grid maintenance programs.
Continuous technological upgrading promotes overall product quality optimization in the industry. Leading export manufacturers have completely eliminated traditional stamping processes and adopted integrated hot forging technology with high-strength carbon steel for UB-10 production. The hot forging process reorganizes the internal grain structure of steel materials, eliminating hidden quality risks such as plate cracking and hole deformation caused by low-cost stamping. Equipped with full-range hot-dip galvanizing treatment, the UB-10 clevis hinge delivers excellent resistance against coastal salt spray, industrial chemical corrosion, and freeze-thaw cycles in alpine regions, greatly extending the overall service cycle of transmission lines. In addition, the dual protection system consisting of high-strength bolts and anti-loose cotter pins fundamentally avoids fastener loosening caused by long-term aeolian vibration and seasonal temperature changes, significantly reducing grid operation failure rates.
Standardized specifications, universal compatibility, and low maintenance costs constitute the core competitive advantages of the UB-10 clevis hinge in global trade. Manufactured in strict accordance with international overhead line fitting standards, the product features unified dimensional parameters and can be seamlessly matched with mainstream global insulators, line clamps, and various connection hardware without customized modification, effectively cutting construction costs and shortening project cycles for overseas clients. At present, high-quality UB-10 products have been widely applied in overseas 110kV and below transmission and distribution projects as well as substation expansion and renovation works. Its stable performance, zero-failure operation record, and long service life ensure continuous repeat orders from global purchasers.
Industry experts point out that with the intelligent and low-carbon upgrading of global power grids, power fittings are no longer simple auxiliary accessories but key components that determine the safety and stability of the entire power system. In the future, standardized forged fittings with superior anti-corrosion performance, optimized structure, and maintenance-free characteristics will dominate the international market. Benefiting from its irreplaceable flexible hinged structure, the UB-10 clevis hinge will further release market potential in cross-border power infrastructure and new energy supporting transmission projects, evolving into a benchmark export product for China's power hardware industry.
