The function of this metal shielding layer is to pass capacitive current during normal operation; When the system is short-circuited, it acts as a channel for short-circuit current and also plays a role in shielding the electric field. What is cable shielding? Shielded cable is, simply, a cable with a conductive shield that protects against electromagnetic interference (EMI). What is. The shielding layer essentially functions as an electromagnetic barrier, achieving interference resistance through two key steps: • Interference Reflection/Absorption: When external electromagnetic signals contact the shielding layer, most of them are reflected back, while a small amount is. Cable shielding is essential to protect data and power transmission from interference, especially in environments with high levels of electromagnetic interference (EMI). The cable conductor is made up of multiple wires twisted, and it is easy to form. In many applications, screening of cables is important, whether it be to minimize cross-talk within the cable, to prevent interference from external sources, or to eliminate radiation from the cable itself.
