S22-M Fully Sealed Oil-Immersed Power Transformer

The S22-M series fully sealed oil-immersed transformer is the new national first-class energy efficiency power distribution equipment, designed in accordance with GB1094 and IEC international standards. Adopting ultra-thin high-permeability grain-oriented silicon steel sheets and optimized five-step lap core structure, it greatly reduces no-load loss and no-load current compared with S13 and S20 models.

This transformer features fully sealed corrugated tank structure, eliminating oil conservator and respirator. The insulating oil is completely isolated from air, achieving maintenance-free operation for decades. With lower operating noise, stronger overload capacity and excellent heat dissipation performance, the S22 series is widely used in outdoor power grids, industrial parks, photovoltaic power stations and rural distribution reconstruction projects.
