Final answer:
False. The high-voltage wires connected to tall metal-frame towers are not wrapped in an insulating material but are held aloft by insulating connectors. These wires are made from materials such as aluminum or copper. preventing the high-voltage wires from coming into direct contact with the metal tower and causing a short circuit.
Step-by-step explanation:
The statement is false. The high-voltage wires that you see connected to tall metal-frame towers are not wrapped in an insulating material. In fact, these wires are bare conductors made from materials such as aluminum or copper. The purpose of the tall metal-frame towers is to provide the necessary support for the wires and keep them at a sufficient height above the ground.
The insulating connectors used to hold the wires aloft are made from materials like porcelain or composite materials. These connectors provide both mechanical support and electrical insulation, preventing the high-voltage wires from coming into direct contact with the metal tower and causing a short circuit.
