S11 Oil-immersed Transformers

S11 oil-immersed transformer is suitable for 10kV, 50Hz transmission and distribution systems. It has high technical content, good energy saving effect, and great value in promotion and application. The performance indicators of this series of products are in compliance with IEC standards and relevant national standards. The product has reasonable structural design, high operating reliability, obvious energy saving effect, strong overload capacity, and low noise. Compared with the S9 transformer, the no-load loss is reduced by an average of 30 to 50%, and the no-load current is reduced by 80 to 90%. This series of products uses corrugated oil tank made of 08 aluminum cold rolled plate, with small size, compact structure and beautiful appearance. The insulating oil in the fuel tank is completely isolated from the outside air, which effectively prevents the oil from getting wet and aging. Under normal conditions of use, 20 years of maintenance-free and maintenance-free, greatly reducing the operating cost of the product, it is the first choice for power grid replacement product.

S11 oil-immersed transformer is a new generation of energy-saving products, with advanced technology, leading performance and technology, novel structure, beautiful appearance and small area, etc.

2. High and low voltage coils are directly wound on the iron core. The two coils have good concentricity and strong resistance to short circuit.

3. Due to the special structure of the iron core, which is formed by annealing of high quality cold rolled silicon steel sheet with crystal orientation, the no-load loss of s11-m transformer is reduced by 30%~50%, the no-load current is reduced by 80%~90%, and the noise is reduced by about 8 db compared with the same capacity s9.

4. Cancel oil storage tank and adopt corrugated oil tank. The oil volume change caused by temperature is adjusted by the elasticity of corrugated sheet, so that the transformer oil and air isolation can extend the service life.

5, the use of corrugated tank low temperature rise, small area, beautiful appearance.

6, the core processing all mechanization, reduce labor intensity, so that the product quality, quality stability.

1. Spiral coil with longitudinal oil channel, better internal heat dissipation;

2. Improved effective support of the coil end face, and stronger resistance to short-circuit current;

3. New hoisting structure and body positioning structure are adopted to ensure more reliability in long-distance transportation and operation;

4. We also have many unique and reliable structures to serve you;

5. The transformer with higher performance level will have higher technical content.

1. The elevation shall not exceed 1000m;

2. The highest temperature is +40 degree

3. The average temperature in the hottest month is +30 degree

4. The highest annual average temperature is +20 degree

5. The minimum outdoor temperature is -25 degree
