Coated iron core ‌ is a process to improve the properties of an iron core by spraying a special material on its surface. The coated core is usually cold-rolled oriented high-quality silicon steel with low iron loss and high permeability, such as 0.23mm or 0.27mm thick silicon steel sheet. This material has the characteristics of high pressure resistance, good insulation and strong protection against copper wire ‌.

Application and effect of spraying iron core

Spray iron core is mainly used in transformers, transformers, inductors and other electrical equipment core components. The spraying process can improve the insulation performance of the iron core, prevent water vapor intrusion, reduce core loss and heat, thereby improving the efficiency and reliability of the equipment ‌.

Material and process of spraying iron core

The material of the spray core is mainly cold-rolled oriented high-quality silicon steel sheet, which has the characteristics of low iron loss and high magnetic permeability. The spraying process usually involves spraying a special coating on the surface of the iron core. This coating can play a role in blocking water vapor, insulating, beautifying the surface of the iron core, reducing loss and heating ‌.

Application areas of coated iron cores

Sprayed iron cores are widely used in various electrical equipment, such as transformers, transformers and inductors.
