10–35 kV Oil-Immersed Transformers
S13-M Series Three-Phase Oil-Immersed Fully Sealed Distribution Transformer. Unlike conventional oil-immersed transformers, this model eliminates the conservator tank and relies instead on corrugated-fin radiators integrated into the transformer tank for heat dissipation and cooling, while the elastic expansion and contraction of the radiator compensates for changes in oil volume. The product features a compact footprint and an aesthetically pleasing appearance, enabling core-free lifting, maintenance-free operation, and low noise levels.
