Screened Control Cables
Screened cables are used to reduce the effects of electromagnetic interference (EMI) or electrical noise which can cause crosstalk in control signals. It also helps to make the electric field distribution within the cable radial.
Screened cables produced using solid, stranded or flexible bare copper insulated with PVC, wrapped with PVC film, braided with solid fine-drawn copper wires and sheathed with PVC.
ASL Wire and Cables offers an exceptional range of screened control cables designed to deliver precise, reliable performance in various industrial and automation applications. Our screened control cables provide superior protection against electrical noise and interference, ensuring accurate signal transmission and control.

Key Features
Screened cables, also known as shielded cables, are designed to minimize the effects of electromagnetic interference (EMI) and electrical noise, which can lead to crosstalk in control signals. Additionally, these cables help to achieve a more uniform electric field distribution within the cable, ensuring better performance and reliability. Here are the key features of screened cables:
- EMI Reduction:
- Purpose: Screened cables are primarily used to reduce electromagnetic interference (EMI) or electrical noise. This ensures that control signals are transmitted with minimal distortion and interference.
- Benefit: This reduction in EMI is crucial for maintaining signal integrity, especially in environments with high levels of electrical noise.
- Crosstalk Prevention:
- Purpose: By minimizing interference, screened cables prevent crosstalk between different control signals.
- Benefit: This ensures that signals are not corrupted or mixed, which is essential for accurate data transmission in control systems.
- Electric Field Distribution:
- Purpose: The screening helps to make the electric field distribution within the cable radial.
- Benefit: This radial distribution helps in achieving a stable and uniform electric field, which enhances the cable’s overall performance and longevity.
- Construction Materials:
- Conductor: Made from solid, stranded, or flexible bare copper, providing good electrical conductivity.
- Insulation: The copper conductors are insulated with PVC (Polyvinyl Chloride), which offers good insulation properties and flexibility.
- Wrapping: The insulated conductors are wrapped with PVC film for additional protection and durability.
- Braiding: The wrapped conductors are braided with solid fine-drawn copper wires. This braiding acts as a shield against EMI.
- Sheath: The entire cable is sheathed with PVC, providing an outer protective layer that is resistant to environmental factors and mechanical stress.
These features make screened cables an excellent choice for applications requiring reliable signal transmission and protection against EMI and crosstalk.
