Product Description
Power Supply 11kv 33kv Oil Immersed Distribution Transformer, 500 kVA Transformer Price
The 6.6kv~35kv oil-immersed transformer produced by Hengfengyou Electric conforms to the national standard gb1094.1-2013 power transformer and GB / t6451-2015 three phase oil immersed power transformer technical parameters and requirements. This product has adopted a series of major reforms in material, technology and structure, so that the electrical performance of the product can reach the advanced level of similar products. With the characteristics of high efficiency and low consumption, it can save a lot of power consumption and operation costs, and has remarkable social benefits. It is a new product promoted by the state. It is also one of the more popular products for users.
2.Main Functions And Features
1. 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.
2. 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.
3. 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.
4. 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
5. The measured noise value is lower than the standard and maintenance free under normal operation.
