LOW PRICE SILICON STEEL LAMINATION TRANSFORMER EI CORE
How Transformers Enable Long-Distance Power Distribution
Transformers are important building blocks in the electrical network for the transmission and distribution of power. Stepping up and down AC voltages to any level is possible with the transformer thanks to Faraday’s law of magnetic induction.
Generated AC voltages are easily transformed into much higher voltages using step-up transformers and then distributed across vast distances using a grid of pylons and cables. The reason for transforming the voltage to a much higher level is that higher distribution voltages imply lower copper losses (I² × R) along the networked grid of cables.
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 the transformer lamination core can be customized.
