EI CORES
Introduce of EI cores
“E” shapes used in “E-E” and “E-I” combinations became popular choices. “Scrapless” “E-I” patterns were
developed. The electrical steel stamped out of two adjacent “E” laminations (placed leg end to leg end) to form
the winding window area became the two “I” laminations to be placed across the leg ends of the “E” laminations.
Since EI-core has two open coil sides, ferrite EI core provide substantial room to bring high current lead wires
out from the coil. This also permits good heat dissipation. Ferrite EI core is easier to achieve high voltage
electrical. EI cores are for mains transformers possess many benefits such as low noise, low magnetising
current, fast assembly, and low cost.
