Product features

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

2. The high and low voltage winding is made of anaerobic copper, and the low-voltage winding 500kVA and the following are double-layered cylindrical structures.

A double helix or four-helix structure is used in 630kVA and above. Multi-layer cylindrical structures are used for high voltage windings.

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

4. The transformer is full seal structure, extending service life, free of hanging core and maintenance.

5. The measured noise is below the standard.

After normal transportation, the series of transformers can be installed with relevant parts, and the test of acceptance test can be put into operation.

Conditions of use

1. the highest temperature: + 40 ℃

2. the lowest temperature: 25 ℃

3. Altitude: <1000m

4. the highest monthly average relative humidity: 90% (20 ℃)

5. Installation site: installed in places without fire, explosion hazard, severe pollution, chemical corrosion and violent shaking, indoor or outdoor.
