Low No-load loss, High Magnetic Flux Density And Electricity Current Standard Iron Core

   The silicon steel sheet core is an iron-silicon alloy formed by adding a small amount of silicon (generally less than 4.5%) to pure iron, which is called silicon steel. This type of iron core has the highest saturation magnetic induction intensity value, which is 20000Gs; Because they have good magnetoelectric properties, easy to produce in large quantities, cheap price, small influence of mechanical stress and other advantages, they have been widely used in the power electronics industry, such as power transformers, distribution transformers, current transformers and other cores. 

   It is also the most widely used material among the magnetic materials used in power transformers. It is especially suitable for low frequency and high power. Commonly used are cold-rolled silicon steel sheet DG3, cold-rolled non-oriented electrical steel strip DW, cold-rolled oriented electrical steel strip DQ, suitable for all kinds of electronic systems, household appliances in the medium and low power low-frequency transformers and chokes, reactors, inductor cores, this kind of alloy has good toughness, can be punched, cut and other processing, the core has laminated and winded. However, the loss increases sharply at high frequencies, and the general frequency does not exceed 400Hz.
