Nanocrystalline core has the advantage of good linearity and stable temperature characteristics, which make it suitable for miniature current transformer.
As our nanocrystalline cores have high permeability and low iron loss, they can replace silicon steel and used as zero phase CT core.
For DC immune current transformers, we can provide the composite core which consists of nanocrystalline and amorphous with plastic case.
Usually the finished mini nanocrystalline cores are protected by epoxy resin coating of plastic cases, both are strong enough for direct winding. But we can also provide other types of encapsulations, such as epoxy harden with crepe paper wrapping or insulation tap wrapping, aluminum box, stainless steel case, and so on.
With more than 15 years’ experience, we can manufacture customized nanocrystalline cores of wide-range dimensions and different magentic property requirements, which can be used for various miniature current transformers of different accuracy class. Due to our quick prototype technology, we can provide samples within a couple of days.
