The transformer, hailed as the "heart" of the power grid, is a crucial hub for voltage conversion and energy transmission within electrical systems. After decades of development, China's transformer industry has established the world's most complete supply chain. Currently, Chinese companies not only lead in traditional "Ultra-High Voltage" (UHV) transmission technology but also demonstrate formidable innovative capabilities in supporting new energy (photovoltaic, wind power) and energy storage sectors. These transformer devices not only underpin the secure operation of China's domestic power grid but also serve as a vital supply source amidst global equipment shortages and surging electricity demand.
The year 2025 witnessed China's transformer industry undergoing a comprehensive upgrade from large-scale manufacturing toward high-reliability, high-efficiency, and digitalized operation and maintenance. Faced with numerous transformer suppliers, determining which brands are more professional and which manufacturers are more reliable has become a common concern for power grid engineers, industrial enterprises, and infrastructure project developers.
