Transformer core provider by Transmart? Transmart Industrial Limited is an one stop solution provider for magnetic cores and chokes, supplying various magnetic cores in Nanocrystalline , Amorphous and Silicon steels, supplying soft magnetic materials, soft magnetic cores, toroidal transformer, nanocrystalline cores, toroidal core, electrical and electronic components as well as other materials for transformers and associated industries. See additional details on magnetic core manufacturers. As we focus on the improvement of the quality, this product has been manufactured with high quality and stable performance. It is of fine workmanship and good quality and is well sold in the domestic market. A positive market response indicates that the product has a good market prospect.

 

We know that the actual transformer always works in AC state, and the power loss is not only on the resistance of the coil, but also in the iron core magnetized by alternating current. Usually, the power loss in the iron core is called “iron loss”. The iron loss is caused by two reasons, one is “hysteresis loss” and the other is “eddy current loss”. Hysteresis loss is the iron loss caused by the hysteresis phenomenon in the magnetization process of the iron core. The size of this loss is directly proportional to the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of transformer core made of silicon steel is small, which can greatly reduce its heating degree.

 

Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel with silicon (silicon is also called silicon), and its silicon content is 0.8 ~ 4.8%. The reason why silicon steel is used as the iron core of transformer is that silicon steel itself is a magnetic material with strong magnetic conductivity. In the energized coil, it can produce large magnetic induction intensity, which can reduce the volume of transformer. rolled silicon steel sheet is selected. It is cut into long pieces according to the size of the required iron core, and then overlapped into “day” shape or “mouth” shape. In principle, in order to reduce eddy current, the thinner the silicon steel sheet, the narrower the spliced strip, and the better the effect. This not only reduces the eddy current loss and temperature rise, but also saves the material of silicon steel sheet. But in fact, when making silicon steel sheet iron core. Not only from the above favorable factors, because making the iron core in that way will greatly increase the working hours and reduce the effective section of the iron core. Therefore, when making transformer iron core with silicon steel sheet, we should start from the specific situation, weigh the advantages and disadvantages and choose the best size.

 

Transmart amorphous core manufacturer supplier is mainly engaged in the production and sales of amorphous core materials. The amorphous core transformer is one of Transmart Industrial’s multiple product series.Transmart Industrial’s amorphous C-core is manufactured in strict accordance with relevant national standards. Every detail matters in the production. Strict cost control promotes the production of high-quality and priced-low product. Such a amorphous transformer is up to customers’ needs for a highly cost-effective product.

 

Now, the test of magnetic core material loss of power frequency power transformer is carried out under sine wave voltage with distortion less than 2%. The actual power frequency power grid distortion is 5%. In this case, the loss of iron-based amorphous alloy increases to 106% and that of silicon steel increases to 123%. If the high-order harmonic is large and the distortion is 75% (such as power frequency rectifier transformer), the loss of iron-based amorphous alloy increases to 160% and the loss of silicon steel increases to more than 300%.

 

The soft magnetic particle core will still be high along the high BS in the future μ、 High Tc, low PC, magnetic powder core is a soft magnetic material made of ferromagnetic powder and insulating medium. Because the ferromagnetic particles are very small (0.55 for high frequency) μ M is separated by non-magnetic electrical insulating film material. Low HC and high frequency, miniaturization and thinness to meet the trend of increasingly thin film, miniaturization and even integration of magnetic components.
