High-Voltage Wires: Insulation Fact Check

No, high-voltage wires are not wrapped in insulating material. The statement that high-voltage wires are wrapped in an insulating material is false.

High-voltage wires on tall towers are bare and are not wrapped in insulating material; only the connectors are insulating.

Explanation:

The statement that high-voltage wires are wrapped in an insulating material is false. These high-voltage wires are bare and not covered in any insulating material. They are suspended in the air, separated from the ground and each other by a considerable distance, which acts as a natural insulator to prevent the flow of electrical current to the structures and the ground.

The only insulating components in this setup are the insulating connectors, or insulators, which are used to attach the wires to the metal-frame towers while preventing electricity from flowing down the towers to the ground.
