S11-M oil-immersed power transformers developed and produced by the company have the advantages of low loss,low noise and high efficiency,which can achieve good energy saving effect and reduce pollution.Compared with the ordinary oil-immersed transformer,the fully sealed transformer cancels the change of the oil volume of the oil storage tank and automatically adjusts and compensates by the elasticity of the corrugated plate of the corrugated oil tank.

Model Number: S11-M                                                                    Rated Capacity: 600kVA 650kVA

The transformer core is made of imported high quality cold-rolled silicon steel sheet,which greatly reduces the no-load loss and no-load current,and laps the core to ensure the compactness of the core and reduce the noise.
The high and low voltage windings are made of oxygen free copper.The low voltage windings of 500 kVA and below adopt double-layer cylinder structure,the double helix or spiral structure is adopted for 630kVA and above,and the high voltage windings adopt multi-layer cylinder structure.
The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the quality of power supply.The measured noise value is below standard.

Advantages of oil immersed transformers：
1.High safety
The fuel tank and oil storage tank have undergone positive and negative pressure leakage tests and have good sealing performance; Adopting an oil immersed design, it can effectively isolate external interference factors.
2.Efficiency
The efficiency of an 11kV three-phase oil immersed transformer can exceed 99%, which can meet the European 2015/2014/548/EC ecodesign Tier 2 energy efficiency regulations.
3.Maintenance free
IP65 protection level, dustproof and moisture-proof, maintenance free, designed for a lifespan of over 25 years.
