Coils: Includes high-voltage and low-voltage side coils, typically made of copper foil or copper busbars to reduce losses and improve conduction efficiency.
Core: Used to concentrate the magnetic field, increasing transformer efficiency, and is usually made of silicon steel sheets to reduce iron losses and improve performance.
Insulation Materials: Dry-type transformers use oil-free insulation materials such as fiberglass cloth and epoxy resin to ensure the equipment's insulation performance and arc resistance.
Casing: The equipment casing is typically made of flame-retardant materials to protect internal components from external environmental influences and ensure stable operation.
