This also permits good heat dissipation. EI-core is characterized by less core loss, high yieldresistance and high permeability, and ferrite EI core is easier to achieve high voltage electrical. Application of EI-core EI cores are used for voltage and current transformers. When EI cores are for mains transformers possess many benefits such as low noise, low magnetising current, fast assembly, and low cost.
