High Performance Low Loss Transformer Core
This high-performance, low-loss transformer core is a high-quality magnetic circuit core component suitable for various high-efficiency transformer equipment, meeting domestic and international energy-saving and efficiency standards. The product uses high-grade oriented silicon steel, iron-based amorphous alloys, and other high-quality raw materials, combined with fully automated precision winding, laser marking, and a 45° fully oblique joint stepped lamination process, significantly reducing core hysteresis and eddy current losses. The product features stable magnetic performance, extremely low no-load loss, low operating noise, and long service life, and is widely used in distribution transformers, dry-type transformers, industrial reactors, UPS uninterruptible power supplies, and new energy inverters, among other electromagnetic equipment.
Compared to ordinary laminated cores, this series of low-loss cores optimizes the magnetic circuit structure, reduces the air gap in the magnetic circuit, and upgrades the interlayer insulation coating and silicon steel sheet thickness ratio, significantly improving the overall energy efficiency of the transformer and helping customers reduce equipment operating power consumption and carbon emissions in the long term.
