The task of core pressing is to arrange, compress, and fix a certain number of laminations into a single, uniformly sized, and tightly packed unit. After core pressing, the core should meet the following technical requirements: 1. Core weight meets the drawing requirements, and the deviation should Read More

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

Grain-Oriented Silicon Steel Lamination is the key material for manufacturing high-performance transformer cores, and stacking these thin silicon steel sheets into a core is the core process that determines transformer performance. The following description covers three aspects: material, structure, Read More
