Details:SIHF GLP
When there is alternating current or alternating electromagnetic field in the conductor, the current distribution inside the conductor is not uniform, and the current is concentrated in the "skin" part of the conductor, that is, the current is concentrated in the thin layer on the outer surface of the conductor. The closer it is to the conductor surface, the higher the current density is, and the actual current inside the conductor is small. As a result, the resistance of the conductor increases, so does its power loss. This phenomenon is called the skin effect. The skin effect of single core cable is obvious and the line loss increases when alternating or alternating electromagnetic field is used.
Advantages of multi-core cable
Multi-core cable refers to the cable with more than one insulated core, so that the skin effect of the cable is reduced, so as to reduce the loss of the line
