Step Down 3 Phase Oil Immersed Power Distribution Transformer

With the company's unique calculation program, the iron core, coil, body, leading wire, fuel tank and other components for the 10-35kV class power and distribution transformers are optimized in all directions to ensure product performance, excellent process equipment, careful material optimization, efficient manufacturing, making the transformer with low loss, low partial discharge, low noise etc., the product quality is superior, with energy saving and environmental protection, reliable operation and effectively reduce the operating costs.

Product Advantages:

1.Compared with S9,S11series Step Down 3 Phase Oil Immersed Power distribution Transformer,the annual average no-load loss of S13 is reduced by 30% and the average load loss is reduced by 20%.At the same time,it saves energy obviously.

2.It has the complete symmetry tri-phased iron core magnetic circuit,which greatly reduces the magnetic resistance and no-load loss,and thus,though adopting the traditional materials,which is more high efficient and energy saving,producing smaller noise and with more compact structure.

 
Applications

 This Low Loss Step Down 3 Phase Oil Immersed Power distribution Transformer is suitable for the core structures in power plants, substations, large-scale industrial and mining and petrochemical enterprises.

Product Features

Based on S9 series, the no-load loss for S11 series Low Loss Step Down 3 Phase Oil Immersed Power Transformers decreased averagely 10.3%, no-load current decreased 22.4%.

The three-phase oil immersed idstribution transformer adpots new type insulation structure and makes the shot-circuit resistance strong.

Transformer tank adopts fully sealed structure, fuel tank and tank rim can be connected by bolts or welded firmly, the transformer oil doesn't contact with the air, extending the service life.

 Improve the relevant sealing parts for the fuel tank, increase the reliability and advance the technical level to ensure the reliability of the seal.

 S11-M series of transformer tank uses the corrugated plate radiator. when the oil temperature changes, the corrugated board expands from the heat and contracts from the cold, which can replace the role of the oil conservator, the corrugated plate type fuel tank has beautiful appearance, less occupied area.

Technical Parameter for S11 Series Step Down 3 Phase Oil Immersed Power distribution Transformer

The Dimension and weight will be changed according to the requirements. These two data in the table will be subject to the factory documents.For the transformer of rated capacity up to 500KVA, the value of load loss above the oblique line in the table is applicable to the connection group Dyn11. The value of load loss under the oblique line is applicable to the connection group Yyn0.

S11 Series 35kV 630kVA-31500kVA Step Down 3 Phase Oil Immersed Power distribution Transformer With Off Circuit Tap Changer

Note: 1: For the transformer of low voltage 10.5kV, the connection group symbol is applicable to Dyn11.
Note: 2: For the transformer of rated capacity 3150kVA or above, the -5% tapping position is for maximum current tap.
Note: 3: When the annual average load rate for the transformer is between 35% to 45%, the loss value in the table can obtain the highest operational efficiency.
