• Product introduction：

On the basis of S9 series, S11 series products have reduced no-load loss by 30% on average and no-load current by 70-80% compared with S9 series. The core is made of imported high magnetic permeability, low loss and cold-rolled high-quality silicon steel sheet, which reduces no-load loss and significantly saves energy. High safety and reliability, advanced structure, small volume, light weight, low noise, low temperature rise, corrosion prevention, reliable leakage prevention measures, eliminate oil leakage phenomenon.

Service environment：

Temperature: temperature: * * + 40 ℃, * * : the average daily temperature + 30 ℃, annual average temperature: * * + 20 ℃, the temperature: * * - 25 ℃.

The elevation of the transformer installation site shall not exceed 1000m, and the temperature rise limit shall be corrected if it exceeds 1000m.

The installation site shall be free from gas, steam, chemical deposit dust, dirt and other explosive and erosive substances that seriously affect the insulation of the transformer

No serious vibration or turbulence in the installation site
