GB20025 High Efficiency Transformer

Energy Efficiency Class I / II Oil-Immersed Transformer Overview

In response to national strategies for energy conservation and emission reduction, our company has developed a full range of oil-immersed transformers that comply with the energy efficiency requirements of the GB20025-2020 standard. By integrating advanced materials, optimized design, and innovative manufacturing processes, these transformers achieve reduced losses, lower operating noise, and improved overall performance. They are ideally suited for use in both urban and rural distribution network centers.

Product Overview

Through continuous research and application of new materials and advanced processes, our company has significantly enhanced transformer performance. Optimized core and winding structures effectively reduce energy loss and noise, ensuring full compliance with the GB20025-2020 energy efficiency standard. Compared with the previous JB/T 10088-2016 noise benchmark, the noise level has been reduced by up to 20%, reaching the domestic advanced performance level.

Among the series, Energy Efficiency Class I oil-immersed transformers feature even lower losses than Class II models, making them ideal for environments requiring high efficiency, reduced operating costs, and long service life.
