S11-M-500kVA Distribution Oil Cooled Transformer

Our S11-M- 500 kVA Distribution Oil Cooled Transformer incorporates advanced technology and superior quality materials, reducing losses, improving power conversion efficiency, and offering considerable energy savings over time. Featuring a primary voltage of 11kV and a secondary voltage of 0.4kV, this transformer has a no-load loss of 680W and a load loss of 5410W.

Product Details:

Type: Oil-Immersed Distribution Transformer
Rated Power: Up to 5,000 kVA
Primary Voltage: Up to 35 kV
Model: S11-500 KVA 11/0.4 kV Transformer (Manufacturing of Oil Tank)

The transformer oil tank is the outer casing of the transformer, filled with transformer oil, which has a great role in both insulation and dissipating heat. The oil increases electrical insulation between internal parts and absorbs the generated heat during operation, which is then released to the atmosphere through the walls of the tank.

Pre-Shipment Inspection:

Visual Inspection

Check the flatness of the tank surface, and observe any dents, deformation, or welding defect. Check that the protective paint applied is even, without peeling, for good appearance and corrosion resistance.

Electrical Performance Testing

Conduct a ratio test by using a ratio bridge in order to measure the voltage ratio of the transformer. The ratio needs to fall within the margin of permissive error; otherwise, voltage output will be affected and might impact system functionality.

Oil Quality Assessment

Check the oil for contamination and water. Admixtures like water reduce the insulation capability of the oil, while contaminants can block passages. Oil cleanliness is vital for the good performance of a transformer.
