Description

1. This model is produced according to China's national GB standard and international IEC standard.

2. Use oil as the main insulation method of the transformer, and use oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation.

3. Main components: iron core, winding, fuel tank, oil pillow, breathing apparatus, explosion-proof tube (pressure relief valve), radiator, insulating sleeve, tap switch, gas relay, thermometer, oil filter, etc.

4. Widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms and oil production platforms; especially suitable for flammable, explosive and other harsh environments.

Note: 1. The dimensions and weight are subject to change as required. The data in the two tables are subject to the factory documents.
2. For transformers with a rated capacity of 500kva and below, the load loss value above the diagonal line in the table applies to the Dyn11 or Yzn11 connection group, and the load loss value below the diagonal line applies to the Yyn0 connection group.
3. When the average load rate of the transformer is between 35%-40%, the highest operating efficiency can be obtained by using the loss value in the table.
