Product Description

product description

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 ordinary oil-immersed transformers, fully sealed transformers eliminate the oil conservator, and the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheets of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging. , Enhance the reliability of operation, and maintain normal operation without maintenance.

Conditions of Use

1. Maximum ambient temperature: +40'C

2. Minimum ambient temperature: -25'C

3. Altitude: <1000m

4. The highest monthly average relative humidity: 90% (20'C)

5. Installation location: Install in a place without fire, explosion hazard, serious pollution, chemical corrosion and severe vibration, indoors or outdoors.

Features

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

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

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

4. The transformer is a fully sealed structure, prolonging the service life, free of hanging cores and maintenance-free.

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