Oil immersed transformer

S11-2000 / 10 oil-immersed transformer

S11-2000 / 10 oil-immersed transformer

S11-2000 / 10 oil-immersed transformer is suitable for 10kV, 50Hz power transmission and distribution system. It has high technical content, good energy saving

S11-2000 / 10 oil-immersed transformer is suitable for 10kV, 50Hz power transmission and distribution system. It has high technical content, good energy saving effect, and great value for promotion and application. The performance indicators of this series of products are in line with IEC standards and related standards. The product has a reasonable structure design, high operational reliability, obvious energy saving effects, strong overload capacity, and low noise. Compared with S9 type transformer, the no-load loss is reduced by 30-50% on average, and the no-load current is reduced by 80-90%. This series of products uses 08 aluminum cold rolled plate made of corrugated fuel tank, small size, compact structure, beautiful appearance. The insulating oil in the fuel tank is completely isolated from the outside air, which effectively prevents the oil from being wet and aging. Under normal use conditions, it is free of maintenance and maintenance for 20 years, which greatly reduces the operating cost of the product. 

S11-2000 / 10 oil-immersed transformer features

11S11-2000 / 10 oil-immersed transformer is a new generation of energy-saving products. It has the characteristics of advanced technology, leading performance technology, novel structure, beautiful appearance and small footprint.

1.The iron core is made of silicon steel sheet rolled without seams and non-gradations which is close to pure circular cross-section. The iron yoke and iron core are connected with rounded corners. The iron core of S11-2000 / 10 oil-immersed transformer is closed.

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

3. Due to the special core structure, it is also annealed by rolling crystalline oriented high-quality cold-rolled silicon steel sheets which makes the S11-2000 / 10 oil-immersed transformer reduce the no-load loss by 30% to 50% compared with the s9 type with the same capacity. 80% ~ 90% reduction, noise reduction by about 8dB.

4. Cancel the oil storage tank and use a corrugated oil tank. The oil volume change caused by temperature is adjusted by the elasticity of the corrugated sheet to isolate the S11-2000 / 10 oil-immersed transformer oil from the air and extend the service life.

5. The use of corrugated fuel tank has low temperature rise, small footprint and beautiful appearance.

6. The core processing of S11-2000 / 10 oil-immersed transformer is all mechanized which reduces labor intensity and improves product quality and quality.

The reliable construction of S11-2000 / 10 oil-immersed transformer

ZTELEC has made many improvements based on traditional structure and mature technology as following

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

2. The effective support of the coil end surface is improved and the ability to withstand short-circuit current is stronger.

3. The new lifting structure of S11-2000 / 10 oil-immersed transformer 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. Selecting a S11-2000 / 10 oil-immersed transformer with a higher performance level will have a higher level of technical content.
