THREE PHASE TRANSFORMER EI CORE LAMINATION SILICON STEEL SHEET
Standard E-I Transformer Construction
The primary and secondary windings are wound on bobbins. Multiple bobbins are placed on spindles and spun in order to apply the windings.
This method of using bobbins allows for automation that reduces the manufacturing times and also provides insulation between the windings and the core. The E-I core laminations are stacked inside the bobbins to complete the transformer. Their ease of construction makes standard E-I transformers very economical to manufacture, which is their primary advantage.
Introduction:
Three phase EI core is made by the silicon steel strip. The model of EI lamination in standard sizes is from
3PEI-17.5 to 3PEI-120.The gap sizes of transformer lamination core can be customized.
