E&I Laminations are used in Transformers which are devices that step up or stepdown the voltage and these transformer core is the E&I Lamination which comes in different sizes.
E&I Laminations types Ranging From EI 29 to EI 350 EI Transformer Laminations and range varieties in UI Laminations, InverterLaminations , Medical Grade Isolation Transformer Laminations, Stabilizer Laminations / 3 Phase Lamination Cores.
E&I typically look like “E” and “I” in English Alphabets, hence the name. The core is punched from high grade, non-aging Cold Rolled Non Grain Oriented (CRNGO) silicon steel laminations conforming to HIB grade of BIS certified with lamination thickness of 0.25mm to 0.5mm. The core will have the Watt loss between 2.5 W – 6W per kg @ 1.5 Tesla at 50 Hz The output parameter requirement will decide the type of lamination to be used and these types range from Type 28 to Type 350.
Industrial Application
Used in transformers, voltage stabilizers, UPS, inverters, converters, lighting ballasts, rectifiers & many more.
Technical Specification
EI laminations are manufactured using various grades & thickness in electrical steel to maintain low watt loss and low off load current. EI Laminations range from Type 38 to Type 350 and the output parameter requirement will decide the EI Lamination Type.
