S13-M Oil-immersed Distribution Transformer

Overview
The S13-M series oil-immersed distribution transformer employs new materials, processes, and structures, with optimized design and meticulous manufacturing. Compared to the S11 type, the no-load loss is reduced by 25%, the no-load current decreases by 35%, and the annual operating cost is reduced by 10.5%.
The core material consists of high-permeability, low-loss premium silicon steel sheets, and the structure features a tension rod clamping rigid frame, providing good stability, low noise, and strong short-circuit resistance. The windings use high-quality oxygen-free copper wire, ensuring good conductivity and low load loss.
