Paper Covered Flat Wire Україна

Paper-wrapped winding wire is a special type of conductor widely used in electrical equipment such as power transformers and motors.

Its basic structure involves wrapping a layer or multiple layers of insulating paper around a conductive metal wire (usually copper or aluminum) to enhance the wire's electrical insulation and thermal properties.
