The S13 model is an upgraded version of our original S11 distribution transformer. It achieves this through the application of new materials and processes, combined with independent innovation and technology transfer. By optimizing and innovating the core and coil structures, it effectively reduces no-load losses and noise. This is 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.
