Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel containing silicon (silicon is also called silicon), and its silicon content ranges from 0.8 to 4.8%. Silicon steel is used as the core of the transformer because silicon steel itself is a magnetic material with strong magnetic permeability. In the energized coil, it can produce a greater magnetic induction intensity, thereby reducing the size of the transformer.
The iron core mainly consists of the iron core body, fasteners and insulation parts:
①The iron core body and magnetic conductor are made of electrical steel sheets.
② Fasteners, clamps, screws, glass strapping, rigid strapping and pads, etc.
③Insulation parts, clamp insulation, insulating tubes and pads, grounding plates and pads, etc.
