Product Description
Overview
The S11-M series fully sealed distribution transformer is suitable for residential communities, commercial centers, high-rise buildings, remote mountainous areas, and places with a lot of dust and pollution. It has high technical content, good energy-saving effects, and great promotional application value. The performance indicators of this series of products meet national standards, with a reasonable product structure design, high operational reliability, significant energy-saving effects, strong overload capacity, and low noise characteristics. Compared to the S9 transformer, the no-load loss is reduced by an average of 30-50%, and the no-load current decreases by 80-90%. This series of products uses corrugated oil tanks made of 08 aluminum cold-rolled plates, which are small in size, compact in structure, and aesthetically pleasing. The insulating oil inside the tank is completely isolated from the outside air, effectively preventing oil from moisture and aging. Under normal operating conditions, it requires no maintenance or inspection for twenty years, greatly reducing the operating costs of the product and making it the preferred choice for power grid upgrades.

Main Technical Parameters
Table 1 Technical Data Sheet for S11-M Series 10kV No-load Voltage Regulation Fully Sealed Distribution Transformer
Note: For 400 and 500 kVA transformers, the high voltage is 10kV or below with a short-circuit impedance of 4%. When the high voltage is 20kV, the short-circuit impedance is 4.5%.
The load loss values above the diagonal line in the table apply to Dyn11 or Yzn11 connection groups, while those below the diagonal line apply to Yyn0 connection groups.
