Screened Cables, also known as Shielded cables, are electrical cables that have a conductive layer (shield) around the inner conductors. This shielding helps to protect the cable from electromagnetic interference (EMI), ensuring signal integrity and reducing noise.

Features of Screened Cables :


Screened cables, also known as shielded cables, are designed to reduce electromagnetic interference (EMI) and protect signal integrity.

  • Shielding Material : Uses metallic shielding (e.g., aluminum foil, braided copper, or a combination) to prevent EMI. Reduces crosstalk between cables and external interference.

  • Enhanced Signal Integrity : Ensures stable signal transmission with minimal loss or distortion. Ideal for sensitive communication and data cables.

  • Protection Against External Noise : Blocks electromagnetic and radio frequency interference (RFI). Suitable for environments with high electrical noise (e.g., industrial sites, power plants).

  • Different Shielding Types:
    » Foil Shielding : Thin aluminum or copper foil provides 100% coverage.
    » Braided Shielding : Woven copper or aluminum strands offer durability and flexibility.
    » Combination Shielding : Uses both foil and braid for enhanced protection.

  • Multiple Applications : Used in data transmission, audio/video systems, industrial automation, and power distribution. Common in networking, medical equipment, and aerospace industries.

  • Improved Safety & Durability : Protects against voltage spikes and reduces signal leakage. Increases cable lifespan, especially in harsh environments.

  • Grounding Requirement : Requires proper grounding to function effectively. Improper grounding may lead to performance issues or increased EMI.


Applications of Screened Cables :


Screened cables, also known as shielded cables, are used in various applications to reduce electromagnetic interference (EMI) and radio frequency interference (RFI). Here are some key applications:

  • Industrial Automation : Used in control systems to prevent interference from motors and high-power equipment. Prevents signal interference in high-electromagnetic environments like factories. Ensures stable communication between sensors, actuators, and control units.

  • Audio & Video Systems : Reduces noise in microphones, speakers, and communication systems. Common in home theater systems and recording studios for high-fidelity signal transmission.

  • Data Transmission : Used in Ethernet, coaxial, and instrumentation cables for signal clarity. Essential in high-speed data transmission networks to reduce crosstalk and external interference.

  • Medical Equipment : Used in sensitive medical devices like ECG, MRI, and ultrasound machines to avoid interference from external electronic sources. Ensures accurate readings and reliable operation in hospitals and diagnostic centers.

  • Power and Electrical Systems : Used in power cables to minimize interference in nearby circuits. Common in renewable energy systems (solar farms, wind turbines) to ensure reliable signal transmission.

  • Railway and Metro Systems : Used in signaling and communication networks to ensure reliable data transfer in high-EMI environments. Prevents disruptions in train control and monitoring systems.

  • Oil and Gas Industry : Used in hazardous environments with high electromagnetic activity, such as drilling rigs and refineries. Protects control and monitoring systems from interference.
