In recent years, the trend for rectangular enameled wires has been to reduce size and weight in most applications while making sub-assemblies as affordable as possible. Therefore, as designers choose to utilize higher coercivity and denser magnetic fields, the frequency is rising. However, as the frequency increases, the loss will increase, and higher coupling and stronger magnetic fields will be generated, which will cause material loss due to two effects (skin effect and proximity effect).

According to the definition, the skin effect loss is caused by the current concentrated on the outer surface of the wire as the frequency increases, and the proximity effect loss is caused by the interaction between the magnetic fields of adjacent conductors, which will affect the current distributed.

As the frequency increases, the current migrates to the skin, and the current is pushed away by the electric field of its adjacent strands, thereby rendering the conductor's core ineffective. The central core becomes wasted space, causing applications to become heavier. If the electromagnetic wire reduces the skin effect and proximity effect loss, resulting in the resistance of AC resistance close to DC, a lot of power can be saved without increasing the quality of copper. CCA Wire is a representative product that produces skin effect. Welcome to consult and contact us for purchase.
