Ring Transformer Iron Core Product Description

Ring Transformer Iron Core Features

Excellent Magnetic Circuit Performance: The annular structure has no obvious seams or very few seams, allowing the magnetic field to conduct smoothly along the ring. This greatly reduces the magnetic resistance and magnetic loss at the seams and improves the efficiency of the magnetic circuit.

 

Low Energy Loss: It is usually made of grain-oriented silicon steel sheets with low iron loss. Combined with the magnetic circuit advantage of the annular structure, it can effectively reduce hysteresis loss and eddy current loss, helping the transformer meet higher energy efficiency standards.

 

Low Operating Noise: The annular structure has better mechanical stability. Under the action of an alternating magnetic field, the vibration amplitude of the iron core is much smaller than that of the traditional laminated iron core, thereby reducing the noise of the transformer during operation.

 

Ring Transformer Iron Core Manufacturing Methods

• Winding Process: Continuous silicon steel sheet strips are directly wound into an annular shape, followed by annealing, curing and other treatments. The iron core made by this process has no seams and optimal magnetic performance, and is mostly used in scenarios with extremely high energy efficiency requirements.

 

• Lamination Process: Silicon steel sheets are cut into fan-shaped pieces of specific shapes, which are then laminated and spliced into an annular shape. This process has high flexibility and can produce iron cores of different specifications, but there are a few seams, and the magnetic performance is slightly inferior to that of the wound iron core.

 

Ring Transformer Core Application 

• High-efficiency distribution transformers, meeting the grid's requirements for low loss and high energy efficiency.
• High-frequency transformers, suitable for scenarios such as communication equipment and new energy inverters.
• Transformers for precision instruments, such as medical equipment and laboratory instruments, which require low noise and stable power supply.
