Improvements in Shielding Technologies for Industrial and Control Cables

Control and automation cables require effective shielding to mitigate electromagnetic interference (EMI). According to IEEE 518, insufficient shielding can cause signal errors as small as 10 mV—yet enough to halt critical industrial systems.

Modern shielding technologies include:

• Aluminum foil shielding for communication cables

• Copper braid shielding for high-noise environments

• Combined (foil + braid) shielding for maximum protection

New advanced systems, such as self-adaptive shielding, dynamically adjust impedance based on signal frequency to improve high-speed data transmission.

These developments ensure higher stability for PLC, SCADA, and other sensitive industrial control systems.
