CRGO Core for Power Transformer Manufacturing is produced from cold rolled grain oriented silicon steel, a material selected for its high magnetic permeability and low core loss in transformer applications. It is used in power transformers, distribution transformers, oil immersed transformers, dry type transformers, and substation equipment. CRGO Core for Power Transformer Manufacturing may use step-lap construction, 45-degree miter joints, precise lamination stacking, and controlled burr processing to improve flux flow, reduce excitation current, and lower transformer noise.
