Application

Paper-insulated wire, also known as paper-covered wire, is widely used in electrical and industrial fields due to its unique insulation properties and durability. Key applications include:

Transformers: Paper-insulated wire is commonly employed in transformer windings. Its layered paper insulation provides excellent dielectric strength, making it suitable for high-voltage applications.
Electric Motors: In motors requiring high thermal resistance, paper-insulated windings help prevent short circuits and enhance operational stability.
Inductors and Coils: The wire's insulation stability at elevated temperatures makes it ideal for inductors in power electronics and telecommunications equipment.
Vintage Electrical Systems: Older industrial machinery or restoration projects often use paper-insulated wires to maintain authenticity and compatibility.
High-Temperature Environments: Its resistance to thermal degradation allows use in applications like furnace wiring or heavy-duty industrial equipment.
Power Distribution: Historically, paper-insulated cables were used in underground power distribution systems due to moisture resistance and mechanical robustness.
