The S22(20)-M-30-2500kVA three-phase oil-immersed fully sealed distribution transformer, unlike ordinary oil-immersed transformers, eliminates the oil conservator and uses the corrugated fins on the oil tank for heat dissipation and cooling. The corrugated design compensates for the expansion and contraction of the oil volume. This series of products is suitable for 10kV, 20kV, and 35kV distribution systems and can be used for residential areas, commercial streets, industrial and mining enterprises, as well as rural power and lighting.
