High heat-resistant three-layer enameled round copper wire is a copper wire with a special insulation structure, suitable for applications in high-temperature environments;

The insulation material of high heat-resistant three-layer enameled round copper wire needs to have good high temperature resistance and electrical insulation properties. Common insulation materials include polyamides (such as polyimide) and polyalkylate insulation paints, which can maintain stable insulation properties in high-temperature environments.

The middle layer of high heat-resistant three-layer enameled round copper wire is usually made of high-temperature heat-resistant resin or rubber material. This layer provides additional protection against high temperatures and enhances the heat resistance of the enameled copper wire.


High heat-resistant three-layer enameled round copper wire usually has a higher heat-resistant temperature and can withstand temperatures up to 200°C or higher. This makes them suitable for high-temperature working environments and able to maintain stable electrical performance at high temperatures.

When selecting high heat-resistant three-layer enameled round copper wire, you need to select the appropriate wire diameter and insulation thickness according to the requirements of the specific application. Larger wire diameter and insulation thickness provide higher current carrying capacity and better insulation performance.

Similar to general enameled copper wires, high heat-resistant three-layer enameled round copper wires also need to have good welding properties to facilitate welding connections during the manufacturing and assembly process. Make sure the selected high heat-resistant three-layer enameled round copper wire can provide a reliable connection when welding.

High heat-resistant three-layer enameled round copper wire is commonly used in various electrical equipment and systems that need to withstand high temperature environments. This includes high temperature motors, transformers, generators, high temperature furnaces, electric furnaces, etc.

When selecting and using high heat-resistant three-layer enameled round copper wire, you should refer to applicable international and industry standards, such as IEC, ANSI, etc. These standards stipulate the material, size, insulation requirements and performance testing methods of high heat-resistant enameled round copper wire to ensure that it meets the standard requirements.

High heat-resistant three-layer enameled round copper wire is widely used in electrical equipment and systems in various high-temperature environments due to its advantages in high-temperature resistance and electrical insulation properties, providing reliable current conduction and insulation protection. The correct selection and use of suitable high heat-resistant three-layer enameled round copper wire is critical to ensuring the performance, reliability and safety of your equipment.
