CORE FEATURES

Paper-covered winding wire is often used in the construction of various types of electromagnetic devices, including power and distribution transformers, motors, reactors, and more.

Conductor Material: The conductor of paper-covered winding wire can be made from copper or aluminum, depending on the specific requirements of the application.

Insulating Paper: High-quality insulating paper is wrapped around the conductor in multiple layers. The paper provides excellent electrical insulation and thermal stability.

Voltage Class: Paper-covered winding wire is commonly used in applications with medium to high voltage requirements due to its excellent insulation properties.

Temperature Class: The temperature class of paper-covered winding wire is determined by the type of insulating paper used.

Impregnation: In some cases, the paper insulation may be impregnated with a suitable insulating varnish or resin to enhance its electrical and mechanical properties.

Layering: The insulating paper is applied in multiple layers, which helps ensure a high level of insulation and protection for the conductor.

Types: single layer paper, double layer paper, paper covered enameled conductor, paper covered bare conductor.
