The electrical steel stamped out of two adjacent ‘E’ laminations to form the winding window area and the I laminations are to be placed along the leg ends of the E laminations. Since EI cores have two open coil side, they provide substantial room to bring high current lead wires out of the coil. This also permits good heat dissipation. Ferrite EI Cores is easier to achieve high electrical voltage. EI cores are applicable in transformers that require low noise, low magnetizing current, fast assembly and low cost.
Introduction:
Single phase EI core is made by the silicon steel strip. The model of EI lamination in standard sizes is from
EI-30 to EI-360.The gap sizes of transformer lamination core can be customized.
