Founded in 1977, Sam Dong has developed a reputation as a leading supplier of high-quality magnet wire suitable for use in a wide range of industries, including automotive, aerospace, medical, and defense. One of our core product offerings is paper-insulated rectangular wire, a conductive material often used in transformers, welding machines, and other electrical equipment.

Our Paper-Insulated Rectangular Wires

Paper-insulated rectangular wires consist of conductive material surrounded by insulating material, such as Kraft paper, thermally stabilized paper, and other similar papers. The addition of insulating paper prevents the conductive component from making contact with other wires and components within an electrical or electronic device. It also serves as a protective layer against moisture and other environmental factors.

At Sam Dong, our highly qualified and awarded team of experts tailors the production of our paper-insulated rectangular wires—including in regard to the type of insulating paper and method of insulation employed—to meet various international industry standards and customer specifications. We offer a wide range of insulating paper material options, including crepe paper, standard and thermally upgraded Kraft paper, and Nomex® paper. Additionally, we can customize the wire order to meet some of the most stringent production requirements, whether a customer needs multiple layers and butt-lapped, overlapped, or interlocked paper insulation.

Industrial Applications of Paper-Insulated Rectangular Wire

Paper-insulated rectangular wires are used as winding coils in a variety of high-voltage electrical and electronic devices, equipment, and systems. Typical products in which they are found include:

  • Generators
  • Manufacturing equipment (e.g., welding systems)
  • Motors
  • Transformers (e.g., dry-type, power, and distribution transformers)

For these and other products, Sam Dong is the ideal supplier of high-quality paper-insulated rectangular wire. Our wires are designed and engineered to comply with both the strictest industry standards and customer specifications.
