S13-M·R (10 kV) Series Three-Phase Wound-Core Fully Sealed Oil-Immersed Distribution Transformer

S11-M·R and S11-M·R three-phase wound‑core, fully sealed distribution transformers feature a core manufactured using specialized winding equipment that continuously coils silicon steel strips into a closed, monolithic structure. This design eliminates the joint gaps typical of conventional cores, significantly reducing noise levels. Following annealing, the no‑load losses are 30% lower than those of stacked‑core designs. The transformer employs a corrugated oil tank with a fully sealed construction, offering an attractive appearance, superior performance, and maintenance‑free operation, making it a next‑generation energy‑efficient and environmentally friendly product.
