Shielded cables are designed to protect signal integrity, reduce interference, and enhance overall performance in demanding conditions. This article explores the importance of shielded cables in hazardous environments, their characteristics, types, applications, and best practices for installation and maintenance. Understanding Shielded Cables Shielded cables, also known as screened cables, are cables that have an additional layer of conductive material surrounding the insulated conductors to protect them from external electromagnetic interference. The shield acts as a barrier that absorbs and reflects electromagnetic interference, preventing it from affecting the signal transmission within the cable. Shielded cables are commonly used in applications where electrical noise, EMI, and radio frequency interference (RFI) can disrupt the signal and lead to malfunctions or safety hazards. Characteristics of Shielded Cables Shielded cables are distinguished by their unique characteristics that make them suitable for hazardous environments. Some key features of shielded cables include: 1. Shielding Material: Shielded cables are typically constructed with a metallic shield made of materials such as aluminum, copper, or a combination of both. The shield can be either braided or foil, each offering specific advantages in terms of flexibility, durability, and EMI protection. 2. Insulation: In addition to the shielding material, shielded cables have insulation around the conductors to prevent electrical contact and ensure signal integrity. The insulation material can vary depending on the application requirements, with options such as PVC, polyethylene, or
