Fully Sealed Oil Immersed Type Transformer Low Noise High Efficiency Energy Saving

Fully Sealed Oil Immersed Type Transformer Low Noise High Efficiency Energy Saving

Compared with the oil storage tank in traditional oil-immersed power transformer, our 12kV fully-sealed transformer has corrugated plate, which adjusts the oil automatically. The oil is isolated from the air, showing no signs of deterioration nor aging problem. That enhances the operation reliability, free maintenance under normal operation.

In addition, the 12kV transformer has features of low loss, low noise and high efficiency, which guarantee good energy-saving with less pollution to the environment.

Structural Features

• The transformer core is made of folded import high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is bound to ensure the compactness and reduce noise.
• The high and low voltage winding is made of oxygen-free copper,. The low voltage winding of 500KVA and below is of double-layer barrel structure, and of 630kVA and above is of double helix or four helix structure. The high-voltage winding normally adopts multi-layer barrels structure.
• Dyn11 method is applied to the transformer connection to reduce the influence of harmonics on the power grid and improve the quality of power supply.
• The transformer is a fully-sealed structure, which can extend its service life, free of core -lifting and maintenance.
• The measured noise value is lower than the standard. After normal transportation, this series of transformers can be installed with relevant parts and components without core- lifting inspection, and can be put into operation after passing the acceptance test.
