SGS is a global inspection, verification, testing and certification organization offering a wide range of certification services. However, the details of SGS certification for a particular product or material may vary depending on the product type, region and specific requirements.

Self-bonding enameled copper wire is a type of wire with a self-adhesive enameled insulation covering the surface of the copper wire.

The insulation of self-adhesive copper enameled wire is usually made of a polyamide resin enamel. This enamel is sticky and can be bonded together during winding to form a uniform and tightly packed insulation layer. This layer not only provides electrical insulation, but also protects the copper wire from moisture, chemicals and mechanical damage.

Self-bonding copper enameled wires typically have good temperature resistance and can operate over a range of temperatures. The specific temperature resistance depends on the enamel material used and the product specification. Typically, self-bonding copper enameled wires are available with temperature resistance ranging from 130°C to 220°C.


Self-bonding copper enameled wire is commonly used in applications such as motors, transformers, inductors and coils. Due to its good insulating properties and temperature resistance, it can provide stable electrical performance in high temperature and high voltage environments. It is widely used in electronic devices, power tools, electrical appliances, automotive industry and aerospace.

The manufacturing process of self-adhesive copper enameled wire includes steps such as drawing, cleaning, enameling and drying of copper wire. In the enameling process, a polyamide resin enamel is coated onto the copper wire and cured by drying. This creates a uniform, tight and adhesive insulating layer.

The main advantage of self-adhesive copper enameled wires is that the insulating layer is self-adhesive and can be bonded automatically during the winding process without the need for additional adhesives or glues. This simplifies the manufacturing process and increases productivity. In addition, the insulation of self-adhesive copper enameled wire is uniform and tightly packed, providing reliable electrical insulation and mechanical protection.

The specific specifications, properties and application requirements of self-bonding copper enameled wire may vary depending on the manufacturer, product standard and particular application. When selecting and using self-bonding copper enameled wire, it is recommended that you refer to the relevant product specifications and technical data and consult with your supplier to ensure that you select the right product for your specific application requirements.
