The S13 type energy efficiency grade three oil-immersed distribution 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 new processes, as well as the combination of independent innovation and technology introduction, and through the optimized and innovative design of the core and coil structure, it aims to reduce no-load losses and noise. The noise level has decreased by an average of 20% compared with the current national standard JBT10088-2004, and the product performance level has reached the advanced domestic level.
