Abstract: As the latest version of energy efficiency standard for power transformers comes into effect officially on June 1st, 2021, loss reducing of transformers becomes a major issue for manufacturers. In this research and development, the low-loss B20R065 silicon steel manufactured by Baowu Steel Group is used for the first time. Followed by a series of supporting measures, namely electromagnetic calculation,structural design and process manufacturing, an advanced laminated core transformer is designed, which is energy-saving, low-noise and environment-protection and meets the new level-2 standard of SB20-M-2500/10.5. Finally, this design scheme is verified to be feasible by the type test.
Key words: transformer; energy efficiency; laminated core
