Multicore cables refer to cables with more than one insulated core. Cable plays an important role in electronic products and systems, and is a key link connecting various functions of electronic products. It is widely used in fields such as aerospace and naval battleships
Advantages of multi-core cables
Skin effect of single core cables
When there is alternating current or alternating electromagnetic field in the conductor, the current distribution inside the conductor is uneven, and the current is concentrated in the "skin" part of the conductor. That is to say, the current is concentrated in the thin layer on the surface of the conductor. The closer it is to the surface of the conductor, the higher the current density, and the actual current inside the conductor is smaller. As a result, the resistance of the conductor increases, resulting in an increase in its loss power. This phenomenon is called skin effect
