S13-M.RL type power transformer
The S13-M oil-immersed power transformer is designed and manufactured with a fully sealed corrugated sheet fuel tank structure, with beautiful appearance and small footprint. Step lap joint can reduce the excessive concentration of iron loss at the joints and cause local overheating.
The S13-M oil-immersed power transformer is designed and manufactured with a fully sealed corrugated sheet fuel tank structure, with beautiful appearance and small footprint. Step lap joint can reduce the excessive concentration of iron loss at the joints and cause local overheating. In terms of product performance, compared with S11 transformers of the same capacity, the no-load loss is reduced by more than 25%, and the noise is reduced by 7-10dB(A). The cost is reduced by an average of 20%, and the economic benefits are significant. The product has the characteristics of maintenance-free, convenient maintenance and stable operation. Can be used in residential areas, commercial streets, industrial and mining enterprises and rural power and lighting purposes.
