Manufacturing Process of Transformer
  • 1. Design and Engineering: Engineers design transformers based on specifications and requirements, considering factors like voltage, power rating, and application.
  • 2. Core Manufacturing: The transformer core is made from high-grade silicon steel sheets stacked and assembled to minimize magnetic losses and maximize efficiency.
  • 3. Winding: Copper or aluminum conductors are wound around the core to create primary and secondary windings. The number of turns and winding configuration are designed to achieve the desired voltage transformation ratio.
  • 4. Insulation: Insulating materials such as paper, press board, and varnish are applied to the windings to prevent electrical breakdown and ensure reliability.
  • 5. Assembly: The core and windings are assembled into the transformer tank, along with other components such as bushings, tap changers, and cooling systems.
  • 6. Vacuum and Impregnation: The transformer tank is evacuated to remove air and moisture, and then filled with insulating oil. The oil is impregnated into the insulation materials to enhance dielectric strength and thermal conductivity.
  • 7. Testing: The transformer undergoes rigorous testing to ensure compliance with quality standards and specifications. This includes tests for insulation resistance, winding resistance, ratio, polarity, and dielectric strength.
  • 8. Finishing and Packaging: After testing, the transformer is painted, labeled, and packaged for shipment to customers. Documentation including test reports and user manuals are provided along with the transformer.
