The S13 model is developed by our company based on the original S11 distribution transformer, through the application of new materials and processes, combined with independent innovation and technology introduction. By optimizing and innovatively designing the core and coil structure, it achieves the goal of reducing no-load losses and noise. An independently developed product.

Noise level is on average 20% lower than the current national standard J*/T10088-2004, with product performance reaching the advanced level domestically.
