FIG. 8 illustrates a messenger supporting cable & clamp system, which typically consists of a messenger cable serving as a structural support and clamps for securing additional cables or components. The system is designed to distribute loads evenly, ensuring stability and preventing sagging. Messenger cables, often made of steel or synthetic materials, withstand tensile forces, while clamps are engineered for easy installation and reliable fixation. This setup is commonly used in overhead wiring, bridge suspensions, or industrial installations to support heavy cables efficiently and safely.
FIG.8 shows a messenger supporting cable, which is designed to bear the weight and tension of messenger wires in overhead power or communication line systems. The cable features a robust structure, made of high-strength materials like steel or composite alloys, to ensure durability and reliability. It have a stranded design for flexibility while maintaining mechanical strength, and connectors or fittings at both ends for secure attachment to supporting structures. This component plays a crucial role in stabilizing the overhead lines, preventing sagging and ensuring safe operation.

The figure 8 cable anchoring clamp is a specialized device for securely fastening cables. Shaped like the numeral "8", it features two loops connected at the center, allowing cables to pass through each loop. Made from durable materials like steel or aluminum, it ensures reliable anchoring by distributing tension evenly. This clamp prevents cable slippage and provides strain relief. Its design allows for easy installation and adjustment, making it essential for maintaining cable stability in various applications.
