Transformer Core

Transformer core

  • Applied materials: It can stably provide the world's first-class high-quality grain-oriented silicon steel sheet materials (Baosteel, Wuhan Iron and Steel, Shougang, Nippon Steel NSC, Kawasaki JFE, Pohang POSCO, Armor AK), optional material thickness: 0.05, 0.08, 0.10mm Ultra-thin silicon steel sheet, 0.1mm super silicon steel sheet, 0.23, 0.27, 0.30, 0.35mm ordinary or high magnetic induction Hi-B silicon steel sheet.
  • Structural features: It is formed by winding a continuous curved belt along the direction of the magnetic circuit. The cross section is rectangular, the window is rectangular, the magnetic circuit is completely closed, and there is no magnetic flux leakage, so its magnetic performance is optimal.
  • Application fields: Widely used in 50Hz transformers, transformers, reactors, choke coils and other electromagnetic components in electronic equipment.
  • Specification range: can be customized according to customer requirements to meet various specifications of customers.
