Tensiune primară: Până la 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.
