Answer :
Final answer:
The statement is false because while high-voltage transmission lines are supported by insulating connectors, the wires themselves are not wrapped in insulating material; they are bare, with air acting as the insulator.
Explanation:
The statement false. High-voltage wires that you see connected to tall metal-frame towers, known as transmission lines, are indeed held aloft by insulating connectors, which prevent electricity from grounding through the towers. However, these wires are not wrapped in an insulating material; they are typically bare wires. The air around the wires acts as the insulator to prevent the electricity from arcing to other nearby conductive structures, and having no insulation allows the wires to dissipate heat more effectively, which is generated due to electrical resistance.
