The S13 oil immersed transformer is a product independently developed by our company based on the original S11 distribution transformer. Through the research and application of new materials and processes, as well as the combination of independent innovation and technology introduction, we optimize and innovate the design of the iron core and coil structure to reduce no-load losses and noise.

The average no-load loss has decreased by 20%. The noise level has decreased by an average of 20% compared to the current national standard JB/T10088-2016, and the product performance level has reached the advanced level in China.
