    Product Detail

    Product Introduction

    The Wound-type annular cut iron core is a high-performance magnetic component engineered for precision and efficiency in modern electrical applications.

    🎯 Application Fields

    Commonly used in small and medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors.

    💎 Core Material

    High permeability permalloy soft tape (e.g., 1J85) offering excellent magnetic permeability and extremely low loss.

    ⚡ Efficiency

    No-load loss reduced by 7%-10% and no-load current reduced by 50%-75% compared to traditional stacked cores.

    🛠️ Exquisite Craftsmanship

    Fully automatic winding ensures a smooth, tight finish with nearly 100% material utilization.

    Technical Features & Process

    Low Noise & Environmental Protection: The integrated structure significantly reduces noise by 5-10dB compared with stacked iron cores, making it ideal for noise-sensitive environments.

    Process Features: Utilizing CNC wire cutting for precise opening sizes. The center line of the incision passes accurately through the center of the inner circle. After specialized annealing, the residual magnetism is maintained at less than 5GS (within a 0~2000GS range).

    The Importance of Annealing

    The winding notched core must undergo a rigorous annealing process after machining. This step is critical to eliminate internal stress generated during production, thereby reducing residual magnetism. This treatment ensures the iron core maintains superior magnetic properties and stability, reducing hysteresis losses and maximizing the efficiency of electromagnetic components.

    Its precise processing technology and excellent mechanical properties make it the ideal choice for high-reliability electromagnetic components, extending the service life of the equipment.

    Frequently Asked Questions

    1. What are the primary applications for wound-type annular cut iron cores?
    They are primarily used in electromagnetic components such as small to medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors due to their high efficiency.
    2. How does the wound core compare to traditional stacked cores?
    Wound cores offer a 7%-10% reduction in no-load loss and a 50%-75% reduction in no-load current. They also operate 5-10dB quieter than stacked cores.
    3. Why is the annealing process necessary for these cores?
    Annealing eliminates internal stress caused during the winding and cutting process. This significantly reduces residual magnetism to less than 5 Gauss, improving magnetic stability.
    4. What materials are used in the production of these cores?
    We use high-permeability permalloy soft tape materials, such as 1J85 and 1J79B, which provide superior magnetic performance and low loss characteristics.
    5. Can the specifications of the iron core be customized?
    Yes, we offer a high degree of customization to meet diverse customer needs, including various dimensions, thicknesses, and specific magnetic property requirements.
    6. What is the material utilization rate during manufacturing?
    Due to the fully automatic winding and CNC wire cutting process, there is no shear waste, resulting in a material utilization rate of nearly 100%.
