Final answer:
The high-voltage wires connected to tall metal-frame towers are not held aloft by insulating connectors, and they are not wrapped in an insulating material.
Step-by-step explanation:
False. The high-voltage wires connected to tall metal-frame towers are not held aloft by insulating connectors, and they are not wrapped in an insulating material. Instead, these wires are supported by the tower structure itself and are designed to be isolated from the tower using insulators.
