These layers—typically made of braided copper wires, aluminum foil, or a combination of both—act as a barrier that reduces electromagnetic interference (EMI). The shield can either absorb or reflect incoming noise, and conduct it to the ground to prevent any from reaching the cable conductors. Here, we will. A typical shielded cable, from the inside out, has the following structure: • Conductor Core: The core (copper or aluminum) that transmits current or signals; • Insulation: Insulates the conductor from the outside, preventing leakage; • Shield: The conductive layer (the core of this article). As discussed in the previous chapter, electronic cables and connectors contribute to system EMI and EMC problems as (1) emitters that radiated part of the con ducted signal and (2) receptors that are susceptible to ambient electromagnetic fields. The purpose of this. Cable shielding plays a key role in keeping communication lines stable, especially in high-noise environments like manufacturing floors, test labs, and mobile equipment.
