Final answer:
High-voltage wires connected to tall metal-frame towers are held aloft by insulating connectors and wrapped in an insulating material.
Step-by-step explanation:
The statement that high-voltage wires connected to tall metal-frame towers are held aloft by insulating connectors and wrapped in an insulating material is true.
High-voltage wires used in power transmission are typically made of aluminum or copper and are covered with an insulating material such as rubber or plastic. The insulating material helps to prevent the electricity from escaping and causing electrical hazards or short circuits.
Additionally, insulating connectors or insulators are used to hold the wires in place and provide electrical isolation from the tower structure, preventing the electricity from flowing into the metal tower and causing potential damage or safety risks.
