The core lamination principles for dry-type transformers and oil-immersed transformers are highly consistent, both pursuing low loss and high magnetic permeability. For example, both commonly use high-quality cold-rolled oriented silicon steel sheets and the 45° fully mitered joint technique. Howeve Read More

I) Preparation Stage: Cutting and DeburringBefore stacking, the large coils of oriented silicon steel need to be processed into sheets of specific shapes.• Slitting: The wide oriented silicon steel coil is cut into strips according to the designed width.• Cross-cutting and blanking: The strips are t Read More
