Transformers: Widely used in windings due to effective insulation and thermal management. Oil-impregnated paper prevents moisture ingress and enhances cooling.
High-Voltage Cables: Historical use in underground/submarine cables; modern alternatives like XLPE are more common but paper persists in niche applications.
Historical Installations: Found in older electrical systems where retrofitting with modern materials is impractical.
