S11-M type fully sealed distribution transformer

This series of products are suitable for rated frequency 50Hz, rated voltage 10KV and the following distribution system, is to reduce power loss, improve power supply quality, enhance the power supply capacity, improve economic efficiency of the product.

Model Meaning

Structural characteristics
S11 type fully sealed distribution transformer adopts high permeability cold rolled silicon steel sheet, which is characterized by low loss, low excitation current and low noise. The coil structure and body insulation adopts new technology, the oil tank adopts fully sealed corrugated oil tank, canceled the oil storage cabinet, added the pressure release valve, beautiful appearance, at the same time, the transformer oil does not contact with the outside air, slowing down the aging of the insulating material, prolonging the service life of the transformer.
Use conditions
The highest ambient temperature does not exceed +40℃, the lowest temperature is not less than -25℃, the highest monthly average temperature +30℃, the highest annual average temperature +20℃.
The middle altitude does not exceed 1000m.
No gas vapors, chemical deposits, dust and dirt and other explosive and erosive media that seriously affect the transformer.
