Design concept of power transformer

(1) Due to the low saturation magnetic flux density of amorphous alloy materials, the rated magnetic flux density should not be too high during product design. A flux density of 1.3–1.35T is generally sufficient to achieve good no-load loss values.

(2) The thickness of a single amorphous alloy sheet is only 0.03mm, so its lamination factor can only reach 82%–86%.

(3) To enable users to obtain maintenance-free or low-maintenance benefits, amorphous alloy distribution transformers are now designed with a fully sealed structure.
