  • Product description
  • Model number
  • Typical graph
  • Main application field
  • The magnetic core of this type of current transformer is made of high permeability iron-based nanocrystalline alloy, which has a very high initial magnetic permeability and a high precision level.

    characteristic

    High initial permeability, maximum permeability greater than 180K

    High voltage output characteristics can effectively reduce the size of magnetic cores

    Low residual magnetism, good resistance to high current impact, ensuring stable tripping current

    The Curie temperature point is high, the temperature stability is good, and it can work for a long time at -55~130 ℃
