Step down Electric Oil Immersed Power Transformer/Distribution Transformer
Product Description
The products are in accordance with Chinese national GB standards and the international IEC standards.
The company manufactures production of S11 – M series the whole sealing oil-immersed power transformer has the advantages of low loss, low noise, high efficiency, can obtain good energy saving effect and reduce pollution. Totally enclosed comparing with ordinary oil-immersed transformer, cancel the oil storage tank, the oil volume changed by corrugated tank elastic corrugated chips to automatically adjusting, transformer is isolated from the rest of the air, to prevent and slow the deterioration of oil and insulation aging, enhance the operation reliability.
