Low Frequency Transformers

Power Capacity by Lamination type:

The selection of the lamination type for a specific transformer depends on the design parameters and the designer’s personal preferences. The indicative power capacity for different lamination types (chart below) provides a general guideline for an initial core selection for electrical transformers. Or refer to our Transformer Size / Power Calculator in our Calculator section:

Note: The power capacity of each lamination type varies due to differences in size, thickness, operating frequency and temperature, flux density and material grade. Chart calculated using 50CS400 grade steel or equivalent laminations.
