S11 oil immersed transformers has 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, S11 oil immersed transformer cancels the oil conservator. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated plate of the corrugated oil tank. The transformer is isolated from the air, so as to prevent and slow down the deterioration of oil and insulation aging, enhance the operation reliability, and avoid maintenance in normal operation.

Conditions of use

1. Maximum monthly average relative humidity: 90% (20 ℃)

2. Installation location: it should be installed in the place without fire, explosion, serious pollution, chemical corrosion and violent vibration, indoor or outdoor.

Product features

1. S11 oil immersed 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 binds the core to ensure the compactness of the core and reduce the noise.

2. The high and low voltage windings are made of oxygen free copper. The low voltage windings of 500KVA and below adopt double-layer cylindrical structure, the high voltage windings of 630kVA and above adopt double helix or four helix structure, and the high voltage windings adopt multi-layer cylindrical structure.

3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the power supply quality.

4. The transformer is of fully sealed structure, which can prolong the service life, avoid core hanging and maintenance.

5. The measured noise value is lower than the standard.
