Introduction

Shielded alarm cables are vital components in security and alarm systems, offering protection against electromagnetic interference (EMI) and ensuring reliable signal transmission. This article provides an in-depth analysis of the use and importance of shielded alarm cables, their technical specifications, and practical applications, along with solutions offered by Aston Cable Company.

Purpose and Functionality of Shielded Alarm Cables

Shielded alarm cables are designed to minimize electromagnetic interference and crosstalk, which can corrupt signal integrity. They feature a protective shield—usually aluminum foil or braided wire—around one or more insulated conductors. This shielding prevents external electromagnetic fields from interfering with the signals traveling through the cable and vice versa.

Technical Specifications

• Conductor Material: Typically copper for optimal conductivity.
• Shield Type: Aluminum foil or braided copper with 85% or more coverage.
• Insulation: Polyethylene or PVC for durability and flexibility.
• Temperature Range: -20°C to 75°C, suitable for most environmental conditions.
• Impedance: Standard 100 to 150 ohms for minimal loss over distance.

Applications in Various Sectors

Shielded alarm cables are used across several industries, including:

• Security Systems: Essential in preventing interference in alarm and access control systems.
• Telecommunications: Protects signals in telephone and data communication systems.
• Industrial Environments: Used in machinery and plant settings where EMI is prevalent.
• Residential Buildings: Deployed in home security and fire alarm systems to ensure reliability.
