Custom Designed Wind Turbine Transformers

Dongan's team of engineers can quickly quote custom transformer units quote for you to review. 

Please have on hand the following information to expedite the quoting process.

1. Phase Requirements (single or three phase).
2. Line Voltage from source - primary input.
3. Load Voltage of load connected to transformer - secondary output.
4. Frequency (in Hertz) of current source. This must match frequency requirements of connected load.
5. Load amps of connected load.
6. Type of Service: General Purpose, Industrial Control, in which the transformer is either open or enclosed.

In most cases, transformers may be selected by answering these six questions. Special applications may require additional information for sizing. Such cases might include installations where the power factor is less than unity, harmonics are present in significant amounts, motors are started and stopped frequently, high ambient temperatures (above 40'C), or a special temperature rise is desired.  

In such instances, Dongan will work with the OEM customer in addressing these needs.
