insulator
意味: A material or device that resists the flow of electric current, heat, or sound, used to prevent unwanted transfer of energy between systems or components.
In electrical engineering, insulators such as rubber, glass, and porcelain are essential for protecting circuits and preventing short circuits. The term extends beyond electricity to thermal insulation in buildings and acoustic insulation in recording studios. In everyday British English, 'insulator' most commonly appears in discussions of home energy efficiency, power line safety, and industrial equipment specifications.
