Product introduction

The S □ -M series three-phase oil immersed transformer produced by the company adopts full oil filled and sealed corrugated oil tank. The oil tank shell adapts to the oil expansion performance with its own elasticity and meets the heat dissipation requirements.
The body adopts a new insulation structure to improve the short-circuit resistance; the core is made of high-quality cold-rolled silicon steel sheet; the high-voltage and low-voltage windings are made of oxygen free copper wires and adopt multi-layer cylindrical structure; all fasteners adopt special anti-loosening treatment.
The product has the characteristics of high efficiency and low loss, can save a lot of power consumption and operating costs, and has significant social benefits. It has been widely used in power plants, substations, industrial and mining enterprises, ports, airports and other places.

Product characteristics

1. The iron core is made of silicon steel sheet with high quality, high performance and high magnetic conductivity, with low no-load
loss.
2. High voltage winding adopts layer structure. Low voltage winding 500KVA and below is layer type, 630kVA and above products
adopt new spiral type. High mechanical strength, balanced ampere turn distribution, strong short circuit resistance.
3. The positioning structure is added to the body to avoid displacement during transportation. At the same time, all fasteners are
equipped with fastening nuts to ensure that the fasteners are not loose during long-term operation.
4. This product is a fully sealed structure. The vacuum oil filling process is adopted when the transformer is packaged, which
completely removes the moisture in the transformer, ensures the isolation of the transformer oil from the outside air, prevents
the aging of the oil, and improves the operation reliability of the transformer. The product is equipped with pressure relief valve,
signal thermometer, gas relay and so on to ensure the safe operation of the transformer.
5. Corrugated oil tank is adopted. This kind of oil tank has the advantages of simple process, high mechanical strength, good welding
effect and no leakage. And because of the strong fluidity of the oil, the heat dissipation capacity of the product is improved.
6. The product is beautiful in appearance, small in volume and small in floor area. It is an ideal maintenance free product.

Note 1 : for transformers wlth rated capacity of 500kVA and below, the load loss values above the diagonal line in the table are applicable to the Dyn11 or Yzn11 coupling group,and the load loss values below the diagonal line are applicable to the Yyn0 coupling group.
Note 2: when the average annual load rate of the transformer is between 35% and 40%, the maximum operating efficiency can be obtained by using the loss value in the table.
