Electromagnetic shielding (electromagnetic shield) refers to the use of conductive materials made of ferromagnetic material or parts to shield the end of large capacity turbo generator stator core, in order to reduce the additional loss caused by the structure of the stator end winding leakage and local heating measures
In communications, shielding is the separation of metals between two spatial regions to control the induction and radiation of an electric field, a magnetic field, and an electromagnetic wave from one region to another. Specifically, the interference source is used will shield components, circuit and assembly, cable or whole system surrounded by preventing electromagnetic interference shielding body outward diffusion; receiving circuit, device or system surrounded, to prevent them from the influence of external electromagnetic field.
Shielding effect is the same, because aluminum is easier to oxidize than copper, difficult to weld and other reasons, the general shielding with copper tape.
