GB 20052-2024 "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Electric Power Transformers" has been officially enforced, and low-efficiency products of S9 and below have been completely withdrawn from the market.

GB 20052-2024 "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Electric Power Transformers" has been officially enforced, and low-efficiency products of S9 and below have been completely withdrawn from the market. For new projects, the proportion of primary energy efficiency transformers is not less than 50%. The industry is accelerating its upgrade towards low loss and high energy efficiency, and the advantages of enterprises with core technologies are further expanded.
