Insulated, or protected, refers to the process of keeping something safe from external influences or conditions. For example, when a house is insulated, it is equipped with materials that help maintain a comfortable temperature inside, shielding it from extreme weather. This can involve using special materials in the walls, roof, and windows to prevent heat loss in winter and keep cool air inside during summer.
In a broader sense, insulation can also apply to electrical systems. Electrical wires are often insulated with plastic or rubber to prevent accidental shocks and short circuits. This protective layer ensures that electricity flows safely, keeping both people and devices secure from potential hazards.
