Main Overview：

The S13 model is a product independently developed on the basis of the original S11 distribution transformer. Through the research and application of new materials and new processes, combined with independent innovation and technology introduction, and by optimizing and innovatively designing the core and coil structures, it achieves the purpose of reducing no-load loss and noise. The noise level is reduced by an average of 20% compared to the current national standard JB/T10088-2016. The product's performance level reaches the domestic advanced level.
