Final answer:
Regular foamboard is recommended when shrinkwrapping to insulate the high-voltage wires connected to metal-frame towers.
Step-by-step explanation:
The statement is true.
When shrinkwrapping, it is recommended to use regular foamboard as an insulating material. This is because regular foamboard has a high insulating capacity, which helps protect the wires from the surrounding environment. The insulating material helps prevent electrical current leakage and potential damage to the wires.
For example, when high-voltage wires are connected to tall metal-frame towers, they are held aloft by insulating connectors and are often wrapped in an insulating material like foamboard. This wrapping helps keep the wires insulated and protected from contact with the tower structure and other objects, reducing the risk of electrical accidents and ensuring the safe transmission of electricity.
