    Product Detail

    Product Introduction

    Wound iron core designed for high-performance electromagnetic applications.

    Application Fields

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

    Core Material

    High permeability permalloy soft tape material, such as 1J85, has excellent performance, high magnetic permeability and low loss.

    Product Advantages

    High efficiency and energy saving. Compared with stacked iron cores, the no-load loss of the wound core is reduced by 7%-10%, and the no-load current is reduced by 50%-75%.

    Exquisite Craftsmanship

    Fully automatic winding, smooth and tight, no shear waste, material utilization rate is nearly 100%, and production efficiency is 5-10 times higher than stacked iron cores.

    Low Noise & Eco-Friendly

    The integrated structure reduces noise by 5-10dB compared with stacked iron cores.

    High Customization

    To meet the diverse needs of customers, various specifications can be customized.

    Process Features

    After high-temperature heat treatment, the performance is stable, and the accuracy of the transformer can reach 0.1 level.

    In the world of electromagnetic components, wirewound toroidal cores are the epitome of efficiency and innovation. Made from high permeability IJ85 material, these cores are designed to meet the stringent requirements of modern electrical applications. The use of platinum alloy soft tape (e.g. 1J85) ensures that these cores exhibit excellent performance, characterized by high permeability and minimal residual magnetism. This makes them indispensable in the construction of small and medium-sized transformers, magnetic amplifiers and earth leakage protectors.

    One of the outstanding features of wound toroid cores is their unparalleled efficiency and energy saving capabilities. Compared with traditional laminated cores, the no-load loss of wound toroidal cores is reduced by 7%-10%, which is impressive. In addition, the no-load current is significantly reduced by 50%-75%. Significant reductions in energy losses mean substantial cost savings and performance improvements, making wirewound toroid cores the first choice for a variety of electromagnetic applications.

    In addition to the technical advantages, wirewound toroidal cores also contribute to quieter, greener operation. The integrated structure of these cores reduces noise levels by 5-10dB compared to stacked cores. The reduction in noise not only creates a more comfortable working environment but also meets ecological sustainability goals, making wirewound toroid cores a responsible choice for modern industry.
