Basic structure of dry-type transformer
1. Iron core: Composed of carefully stacked silicon steel sheets, the iron core is the magnetic circuit component of the transformer, crucial for guiding the magnetic flux with precision.
2. Winding: Featuring distinct high-voltage and low-voltage windings meticulously wrapped around the iron core, facilitating the seamless conversion and effective transmission of electric energy.
3. Insulating cylinder: Strategically positioned between high and low voltage coils, this cylinder enhances electrical insulation, ensuring the transformer's reliable and safe operation.
4. Pads: Designed to support and restrain the coils, these components maintain their stability and shape, preventing mechanical displacement.
5. Fasteners: These connectors secure and fix each part of the transformer, boasting superior anti-loosening performance for enhanced durability.
