Driven by national energy conservation and environmental protection policies, amorphous alloy transformers have been widely adopted in the power distribution sector. Continuous technological advancements have fueled the rapid development of amorphous alloy 3D wound-core transformers, making them an emerging hotspot in power distribution. Departing from the planar wound-core structure of traditional amorphous alloy transformers, our company utilizes a three-dimensional (3D) wound-core structure combined with low-loss alloy ribbons to manufacture these advanced units. Consequently, our products feature high core strength, robust short-circuit withstand capability, uniform temperature rise, low noise levels, balanced three-phase performance, low no-load current, minimized material and energy consumption, and low stray flux leakage.
The amorphous 3D wound core is assembled from three identical, independent frames. Once assembled, the equilateral triangular 3D structure provides exceptional stability, high mechanical strength, uniform three-phase stress, and excellent short-circuit resistance. Under identical conditions, amorphous alloy 3D wound-core transformers deliver lower noise, enhanced localized short-circuit resistance, reduced dimensions and weight, as well as lower production and operating costs. Therefore, amorphous alloy 3D wound-core transformers hold broad application prospects and significant socio-economic value.

Robust Core Structure: The monolithic core features a tightly wound, enclosed amorphous ribbon structure that is exceptionally strong and stable, preventing debris generation during operation. Additionally, the core is fully reusable during transformer maintenance.
Excellent Short-Circuit Resistance: Delivers robust short-circuit withstand capability, balanced three-phase performance, and low noise levels.
Uniform Heat Dissipation: Ensures uniform temperature rise during heating, utilizing a circular coil cross-section and evenly distributed oil or air cooling channels.
Reduced Material Consumption: Optimizes material usage, with the yoke cross-sectional area being only half of the core cross-sectional area.
Minimized No-Load Loss & Current: Through structural and technological innovations, the total core weight has been significantly reduced. Featuring continuous winding and a seamless core, it minimizes air-gap losses and drastically reduces magnetic reluctance. This results in a substantial decrease in no-load current, which is on average 60% to 80% lower than the national standard.
