Silicon steel is an alloy, adding a small amount of silicon in pure iron (generally below 4.5%) the formation of iron-silicon alloy known as silicon steel, this type of core has the highest saturation magnetic induction strength value of 20,000 gauss,due to their better magnetoelectric properties, but also easy to mass-produce, inexpensive, the impact of mechanical stress and other advantages.

 

In the power electronics industry to obtain an extremely wide range of applications, such as power transformer Power transformers, distribution transformers, current transformers and other cores.

 

For small motors, reactors and relays, pure iron or low-silicon steel sheet; for large motors, high silicon hot-rolled silicon steel sheet, single-orientation or non-orientation cold-rolled silicon steel sheet; transformers are often selected single-orientation cold-rolled silicon steel sheet.

 

In the frequency of use, commonly used strip thickness of 0.2 ~ 0.35 mm; in the use of 400Hz, often choose 0.1 mm thickness is appropriate. The thinner the thickness, the higher the price.

Silicon Steel Sheet CT Core Toroidal Transformer Iron Core Feature

 

Introduction of chemical rust prevention technology for silicon steel based on passivation technology

Basic Features:

• New antirust technology;
• Based on the principle of redox reaction, using a strong reducing agent in the solution containing metal ions will be reduced to metal, and deposited on the surface of the material to form a dense metal film layer;
• The protective film is attached to the surface of the iron core in solid form, cannot be diluted, has strong adhesive force, is not easy to fall off, and is not easy to have chemical reaction with impurities in the air;
• Long service life.
