Description

Technical Field

[0001] The utility model belongs to the technical field of iron cores, and in particular relates to an open type mutual inductor iron core. Background Art

[0002] Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a type of steel containing silicon (also known as silicon), with a silicon content of 0.8-4.8%. Silicon steel is used as the core of the transformer because it is a magnetic material with strong magnetic conductivity. In the energized coil, it can generate a large magnetic induction intensity, thereby reducing the size of the transformer.
