Product Description

 50kVA 11/0.415kv Oil Cooled Transformer, 3 Phase Copper Winding with Competitive Price

 

Product introduction

* The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is tightly bound to ensure the compactness and reduce noise.
*  The high and low voltage windings are made of oxygen-free copper. The low voltage winding of 500KVA and below is of double-layer cylinder structure, of 630kVA and above adopt double helix or four helix structure. High-voltage winding adopts multi-layer cylinder structure.
*  Dyn11 is used in the transformer connection group to reduce the influence of harmonics on the power grid and improve the quality of power supply.
* The transformer is a fully sealed structure, with three coats of primer and one coat of finish paint applied on the inner and outer surfaces. The product is salt fog proof, moisture proof and fungus-proofing, beautiful, durable and reliable
* The measured noise value is lower than the standard and maintenance free under normal operation.

Product features

1,using the corrugated tank sealing structure, enclosure, to prevent contact with air, water in contact with the transformer, reducing the degree of aging of the oil, to extend the service life of the transformer; Through the elastic deformation of corrugated to adjust the volume change of transformer oil heat bilges cold shrink.
2,the product structure for the outdoor type, oil-free pillow,anti-fouling high level; ensure safe operation and reliability of the grid.
3,the transformer has a pressure release safety devices, when a transformer failure pressure is too high. It can be safely released reliably through the pressure relief valve to prevent the expansion of the accident.
