Final answer:
The high-voltage wires connected to 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 suspension insulators that hang the wires from the towers.
Step-by-step explanation:
False
The high-voltage wires connected to 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 suspension insulators that hang the wires from the towers. These insulators are made of materials such as porcelain or glass and are used to prevent the metal towers from becoming electrically charged.
