Product Introduction

S11-M series 10kV full-sealed power transformer is a new product developed by our company in line with the national standard. It has the advantages of compact structure, beautiful appearance, small size, low temperature noise,and strong overload capacity. These feature makes it one of the most energy-saving products in China.

Product Features

The corrugated oil tank of transformer is fully sealed, which can prevent air and moisture from contacting with transformer oil, reduce the aging degree of the oil and prolong the service life of the transformer. Through the elastic deformation of the corrugated sheet, the volume changes of transformer oil can be adjusted when oil expands with heat and contracts with cold.

 

The product adopts outdoor type structure and has high anti-pollution level without grease. There is no need to replace the transformer oil under normal conditions of use, so as to avoid maintenance and ensure the safe operation and reliability of the power grid.

 

The transformer is equipped with pressure relief safety protection. When the transformer fails and the pressure is too high, workers can operate the pressure relief valve to prevent the accident from expanding.

When the transformer has a high failure pressure, it can release the valve safely and prevent the situation from getting worse.

 

There are two kinds of sealing forms, namely welding and fastening with bolt for users.
