Product Features of Ei Lamination Core
High-efficiency Magnetic Circuit Design:
The Core Lamination uses a core ei structure to optimize the magnetic circuit path, reducing eddy current losses and improving efficiency to over 98%.
Low Energy Consumption and Stability:
The Laminated core of transformer reduces iron loss and noise through precision stacking technology, ensuring long-term stable operation at a frequency of 50Hz.
Environmentally-friendly and Durability:
The surface of the Laminated iron core has an insulating coating that suppresses partial discharge, with a chrome-free passivation process meeting RoHS standards, extending service life.
Flexible Adaptability:
The modular structure of Core Lamination supports quick disassembly and assembly, compatible with retrofitting and maintenance needs of transformers from different brands.
