From the different specifications of voltage, the power transformers are divided into many types such as 36 volts, 110 volts, 0.4 kV, 10 kV, 22 kV, 6 kV, 35 kV, 110 kV, 220 kV, 350 kV, 200 kV, 500 thousand V, 250 kV, and 600 kV.
From the different specifications of capacity, the power transformers can be divided into 50KVA, 80KVA, 100KVA, etc. just in accordance with the R10 first factor, i.e. the opening of the 10 th of 10 times to calculate.
There are too many models of the power transformers all over in China,
Now you will see the models of power transformers:
The number of power transformer windings+ Phase + Cooling methods + Whether forced oil circulation+ Load or no load tap + Design Number +"-"+ Capacity + Composed of high-pressure side of the rated voltage.
For example: SFPZ9-120000/110 refers to the three phase transformers(two-winding transformer winding is omitted, and if there are three around the front of a S) double winding forced oil circulation cooled OLTC, No 9design, capacity of 120000KVA, the power transformer of high-pressure 110KV rated voltage.
For the capacity, the national capacity standards are as follows: 30,50,63,80,100,125,160,200,250,315,400,500,630,800,1000,1250,1600,2000 for the power transformers.
