Basic structure of wire and cable
Conductor: An object that conducts current, and the specifications of the wire and cable are represented by the cross section of the conductor.
Insulation: The insulating material is wrapped around the conductor with different thicknesses according to the requirements of the withstand voltage.
Protective layer: The part that protects the cable.
