Final answer:
The high-voltage wires connected to tall metal-frame towers are indeed held aloft by insulating connectors and wrapped in an insulating material.
Step-by-step explanation:
True
The high-voltage wires that you see connected to tall metal-frame towers are indeed held aloft by insulating connectors and wrapped in an insulating material. Insulating connectors prevent the wires from coming into direct contact with the tower, reducing the risk of electrical current flowing through the tower and causing damage or injury. The insulating material surrounding the wires helps to prevent electrical current from escaping and increases safety.
