Final answer:
The high-voltage wires connected to metal-frame towers are not wrapped in insulating material but are held aloft by insulating connectors. The surrounding air provides sufficient insulation for these wires.
So option (B) is correct.
Step-by-step explanation:
The statement that the high-voltage wires you see connected to tall metal-frame towers are wrapped in an insulating material is false. These wires are indeed held aloft by insulating connectors, often made from materials like porcelain or glass, which are designed to prevent the electricity from arcing to the towers themselves. However, the wires are typically not wrapped in an insulating material. The reason they do not require additional insulation like wires used in residential or commercial settings is that the air surrounding the high-voltage wires acts as a sufficient insulator. As long as the wires are a safe distance away from any conductive materials, they do not present a risk of electrical leakage or short-circuiting.
Pallet pools are not designated areas where pallets are physically stored; instead, they refer to a system or network for efficiently managing and sharing pallets among multiple users or companies. In a pallet pool system, pallets are circulated, reused, and shared within a community of businesses, reducing the need for each individual participant to maintain and store large quantities of pallets. The primary goal is to optimize pallet usage and minimize waste.
The false statement suggests a more static and localized understanding of pallet pools, which doesn't align with the dynamic and collaborative nature of a pallet pool system. In a pallet pool, pallets move through the supply chain, being used and reused by different entities, and are not simply stored in a designated area. This approach enhances sustainability and cost-effectiveness in logistics and distribution processes.
