Brief  introduction

• The inside of oil tank of the transformers is completely isolated from the outside, the change of transformer oil volume is compensated by expansion and contraction of corrugated tank wall, thus water and oxygen can not enter the internal of the tank, on one hand, it does not reduce the insulation strength, on the other hand, it can avoid the aging of insulating materials. The products need not be lifted for core check before the commission, after putting into operation, no maintenance and repair is needed either, this can greatly improve the reliability of transformer.
  
  
• The products can be used in various fields, possible applications includes: industrial and petrochemical plants, railways, coal mines and other industries, public places, indoor or outdoor unit substation, it can be especially used as rural and urban power grid distribution equipment.
