Homonym: insulated (Protected)
"Insulated" refers to the process of protecting something from outside influences, especially heat or electricity. For example, when a house is insulated, it means that materials like fiberglass or foam are used to keep the warmth inside during winter and the heat outside during summer. This helps maintain a comfortable temperature and can save energy costs.
In electrical terms, insulation is crucial for safety. Wires are often covered with materials like rubber or plastic to prevent electric shocks. This protective layer ensures that electricity flows safely through the wires without leaking out, making it safer for people to use electrical devices.
