POWER CAPACITY BY CORE TYPE

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:
