Winding wire diameter

The program allows the calculation of the minimum diameter of the winding wire at the required current flowing through it.

Current density | [A/mm2] | ||

Current in conductor | [A] | ||

Notes:

- Specify the value of current density and current in the wire and press [Calculate]. Winding wire diameter (in millimeters to two decimal places) will be shown in the figure on the left.
- Results of calculations can be used to determine the diameter of the wires used in mains/power and output transformers.
- It is important to provide the correct value of current density. The default value is 2.5 [A/mm2] and for the copper wire can be successfully used in most practical applications.
