Amorphous Alloy Core offers up to 70% lower no-load loss compared with traditional silicon steel cores. Ideal for oil immersed transformers, dry type transformers, distribution transformers, and energy-saving power systems.
As global power systems move toward higher efficiency and lower carbon emissions, transformer core materials have become a critical factor in reducing energy loss. The Amorphous Alloy Core is one of the most advanced solutions for modern distribution transformers, offering significantly lower no-load loss compared with traditional silicon steel cores.
With up to 70% lower core loss, excellent magnetic properties, and superior energy-saving performance, amorphous alloy transformer cores are widely used in utility substations, renewable energy projects, industrial power distribution systems, urban grid upgrades, and high-efficiency power transformer manufacturing.
ZTELEC YUGUANG provides high-quality amorphous alloy transformer cores designed for oil immersed transformers, dry type transformers, pad mounted transformers, pole mounted transformers, and compact substations.
An amorphous alloy core is made from ultra-thin metallic glass ribbons produced through rapid solidification technology. Unlike conventional CRGO silicon steel sheets, amorphous alloy materials have a non-crystalline atomic structure, which greatly reduces hysteresis loss and eddy current loss.
This unique structure allows transformers equipped with amorphous alloy cores to achieve exceptional no-load efficiency, making them ideal for power systems operating continuously for 24 hours a day.
Compared with conventional silicon steel transformer cores, amorphous alloy cores can reduce no-load loss by 60% to 80%, significantly lowering long-term operating costs.
Lower energy loss means reduced electricity waste, improved transformer efficiency, and better compliance with modern energy-saving regulations and utility standards.
Reduced magnetic loss results in lower heat generation, improving transformer lifespan and system reliability.
Lower power consumption helps reduce carbon emissions and supports green power infrastructure and sustainable grid development.
Stable magnetic performance and excellent corrosion resistance ensure reliable long-term operation in demanding environments.
