Do you know what shielding materials are used on toroidal transformers?

Normally, the shielding materials used on toroidal transformers are magnetic materials, such as nickel-zinc (Ni-Zn) magnetic powder, ferrite, etc.

These magnetic materials have excellent magnetic permeability and wear resistance, and can effectively absorb the surrounding electromagnetic interference signals to prevent them from affecting the performance of the transformer. In addition, these materials also have the function of suppressing the AC leakage magnetic field, which effectively reduces the leakage magnetic field of the transformer in high-power applications.

In addition to magnetic materials, the shielding materials of toroidal transformers also include non-magnetic materials such as metal films and plastic films. These materials are mainly used to manufacture capacitive shielding devices to better filter high-frequency noise and electromagnetic radiation.

EEIO Transformer's toroidal power transformer is made of high-flux non-leakage magnetic silicon steel sheet core + pure copper wire + polyester film and other materials. The product has obtained EU CE certification, CQC China Quality Certification, Configuration Material SGS Certification and other certification certificates. The product is strictly inspected before leaving the factory to eliminate defective products, so that customers can buy and use it with confidence.
