Step-Lap Transformer Core Lamination is the silicon steel sheet cut into 45 ° oblique angle after staggered stacked core structure, compared with the traditional straight sewing stacked sheet, it can greatly reduce the seam air gap, reduce no-load loss and noise, improve the continuity of the magnetic circuit and operating efficiency, is the core process of high-performance transformers.
Step-Lap Transformer Core Lamination effectively reduces the concentration of magnetic flux by dispersing the seams in different levels and avoiding the concentration of magnetic circuit through a single straight seam; the magnetic circuit is more continuous and smooth, significantly weakening the magnetostrictive vibration at the seam, thus reducing the noise; and at the same time, minimizing the air gap of the seams reduces the magnetoresistance and eddy current, hysteresis loss, and ultimately realizes the significant reduction of no-load loss.
Step-Lap Transformer Core Laminations are widely used in distribution transformers, power transformers, dry-type transformers, new energy transformers, reactor cores, current transformers, and other electrical equipment requiring efficient magnetic circuits. Compared with the traditional straight-cut structure, the Step-Lap process can effectively reduce no-load loss, operating noise and magnetic flux concentration phenomenon, and at the same time improve the transformer’s energy efficiency, magnetic performance and operational stability, especially for energy-saving power systems, industrial power distribution and new energy and other applications that require high efficiency and high reliability.
