S11-M, S11 series oil-immersed power transformer is a new type product conforming to national standards, compact, aesthetic, small, with low noise and temperature rise, strong overload capacity. Compared with S9 series, the no load loss reduced by as much as 30% and the no load current by 45%~80%, which is one of most energy efficient product series in China.
Product Features
The transformer is designed with corrugated tank and hermetical seal to prevent air and water from contacting the transformer, which results in reduce of oil aging and extension of the service life; through elastic deformation of corrugated cooling metal, the transformer’s oil volume is regulated.
The product is for outdoor use, without conservator, highly anti-contamination; during regular running, no need to replace oil, truly maintenance-free, ensuring safe operation and reliability of the grid.
The transformer has a pressure relief valve, when a transformer run into failure and the pressure is too high, it can be safely released through the pressure relief valve to prevent the accident from deteriorating further.
