The S -M Series Oil-Immersed Distribution Transformer is a state-of-the-art, three phase transformer developed to enhance reliability and performance over the S9 series.By refining loss coefficients and optimizing the copper-to-iron ratio, it achieves superior loss design and cost-effectiveness. The iron core utilizes high-conductivity, low-loss silicon steel, minimizing no-load losses.
For high-voltage windings, a multi-layer structure is employed, with products up to 500kVA featuring multi-layer low-voltage windings. For transformers of 630kVA and above, a new spiral type for low-voltage windings is used, improving electrical performance and mechanical strength, especially during short circuits.
