NiFe-based Mu Metal Shielding Tube for Current Transformer
Shielding tube is a major protecting method in magetic fields, which obtains double actions: one is to prevent or reduce the electromagnetic interference from outer field, the other is to prevent or reduce the part's own electromagnetic field affecting any other relevant parts.
Mu Metal Shielding tubes including one-piece shield, two-piece shields and multi-compartmental shield are packaged for surface mount applications for a wide range of industries.
The material required for shielding are mainly conducting materials with low resistivity & high permeability. The most effective magnetic shielding material available is Mu Metal, an alloy of 77% nickel, 16% iron, 5% copper, and 2% chromium, which is then annealed in a hydrogen atmosphere to increase its permeability. As mu-metal is comparatively expensive, other alloys with similar compositions are also applied for magnetic shielding, which contains around 80% nickel.
