Application

The S11-M series fully sealed oil immersed power transformer developed and produced by our company 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, the fully sealed transformer cancels the oil conservator, and the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated mailbox. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging, enhance the operation reliability, and the normal operation is maintenance free.

Working Conditions

1. Maximum ambient temperature: + 40 ℃
2. Minimum ambient temperature: - 25 ℃
3. Altitude: < 1000m
4. Maximum monthly average relative humidity: 90% (20 ℃)

5. Installation location: it should be installed in a place without fire, explosion hazard, serious pollution, chemical corrosion and violent vibration, indoors or outdoors.
6.If any special working conditions that are not in line with the above stipulations, user shall negotiate with us.



Model and Its meaning




Product Features

1. The transformer iron core is made of imported high-quality cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current. The iron core is bound to ensure the compactness of the iron core and reduce the noise.

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

3. Transformer connection group adopts Dyn11 to reduce the impact of harmonic on power grid and improve power supply quality.

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

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