Double insulated polyimide copper enameled wires offer excellent resistance to high temperatures. Both the polyimide film and the polyamide acid ester enamel are high-temperature materials that can withstand applications up to 200°C or more. This makes double insulated polyimide copper enameled wire ideal for use in electrical equipment and systems operating at high temperatures.

Double insulated polyimide copper enameled wire has excellent electrical properties, including low electrical resistance and good insulation. The copper conductor has good electrical conductivity and conducts current efficiently. At the same time, the polyimide film and polyamide acid ester enamel provide reliable electrical isolation and insulation protection, reducing the risk of electrical failure.

The polyamide acid ester enamel layer of double insulated polyimide copper enameled wire has good abrasion and chemical resistance. This enables the wire to resist mechanical abrasion and corrosion by a number of chemicals in harsh operating environments, extending its service life.


Despite the double insulation, double insulated polyimide copper enameled wire is still flexible and bendable, making it easy to install and route. This makes it suitable for application scenarios that require bending and connecting, and can be adapted to different shapes and sizes of installation spaces.

Applicable electrical standards and codes should be followed when selecting and using double insulated polyimide copper enameled wire. These standards and codes typically specify the wire's current rating, temperature class, insulation requirements, and other important parameters to ensure that the wire is safe and performs as required.

When using double insulated polyimide copper enameled wire, its suitability should be carefully evaluated and it should be installed and used in accordance with the manufacturer's instructions and recommendations. This will ensure that the wire will provide a reliable electrical connection and protection for its design life.
