Transformer Iron Core for Distribution Transformer is the magnetic circuit that guides flux and directly affects transformer efficiency, no-load current, noise level, and temperature rise. It is commonly made from grain-oriented silicon steel sheets with precise lamination, step-lap or mitered joints, and controlled stacking quality. Transformer Iron Core for Distribution Transformer is used in 10kV, 11kV, 35kV, oil immersed, dry type, pole mounted, pad mounted, and substation distribution transformers. Accurate core processing helps improve electrical performance and reduce vibration.
