Nanocrystalline Core for Switchgear

Switchgears, which provides protection to electrical appliances and control the sources, are important in power systems. By comparison with the conventional silicion steel or permalloy cores, Xianyu nanocrystalline cores have the many advantages, such as high magentic permeability, high Bs value. Thus, the current transformers made by nanocrystalline cores are very suitable for LV, MV switchgear applied in power transmission and distribution system.

We provide toroidal nanocrystalline cores, special shape nanocrystalline cores, like oval, rectangular or oblong cores are also available. We can assist in custom design of nanocrystalline cores and provide samples within a couple of days.
