Super Core Characteristics


 

  • Low Core Loss

Low core loss at high frequencies improves equipment efficiency and reduce energy consumption of reactors and transformers.

 

  • Low Magnetostriction

Magnetostriction causes nearly zero noise and vibration and significantly reduces the noise of magnetic components such as reactors and transformers.

 

  • High Permeability

For shields applications and CT.

 

  • Stable Quality

The high-temperature process improves thermal stability. Since machining can cause performance degradation, stress-relieving annealing is not required.

 

  • Non-oriented

There is virtually no difference between the rolling direction (L-direction) and the transverse (C-direction) in the characteristics. Therefore, the Super Core can be used for stationary or rolling machines.

Super Core Application


 

  • Transformers

With the characteristic of low core loss at high-frequency, the Super Core can be used for various types of transformers in a wide range of frequencies (x Hz to y kHz).

 

Super Core helps reduce heat generation in transformers and provides higher magnetic induction intensity than conventional silicon steel sheets, which can reduce the size of transformers. Other required components of transformer, such as the copper wire, can be downsized accordingly, resulting in overall cost reduction.

 

By taking the advantage of the low magnetostriction characteristics of JNEX-Core, the noise of transformers CAN be reduced dramatically.

 

  • Reactors

 

With the characteristics of high saturation magnetic flux density, low core loss at high-frequency, and high permeability, Super Core is ideal for applying to reactors with high-frequency current superimposition over a broad range of frequencies.

 

Super Core meets all high frequency wave regulations and power factor improvements. The demand is on the increase for its use in inverter output reactors, active filters, PWM converter reactors. It serves many market sectors, including consumer electronics, industrial renewable power generation, and automobile market.

 

Super Core meets diverse needs of customers. It can be formed into wound cores in various shapes, such as C-Cores and toroidal cores, as well as into lamination cores, glued block cores by cutting or pressing.
