180 class polyesterimide enameled aluminum (copper) round wire

180 class polyesterimide enameled aluminum (copper) round wire is a high-temperature resistant enameled wire. It is made of electrical round aluminum rod or oxygen-free copper rod after die drawing annealing treatment of required specifications, and then polyesterimide paint is applied on its surface and then processed by baking and other processes.

Polyesterimide paint is a high-performance insulating paint with excellent heat resistance, electrical properties and mechanical properties. 180 class refers to the temperature resistance grade of the enameled wire, indicating that the maximum temperature it can withstand during long-term work is 180℃, corresponding to the H grade in the international standard. 180 class polyesterimide enameled aluminum (copper) round wire is a high-performance enameled wire with excellent heat resistance, suitable for applications in various high-temperature environments.

◆ Excellent heat resistance: Able to work for a long time in a high temperature environment of 180℃.

◆ It has good paint film toughness and scratch resistance, suitable for automatic winding and embedding.

◆ Good mechanical strength: Able to withstand certain tension and bending, convenient for winding coils.

◆ Good chemical corrosion resistance: In addition to strong acids, chloride ion salts, and organic compounds, it also has good resistance to acids, alkalis, and most organic solvents.

◆ Good moisture resistance: Not easily affected by humid environments.

◆ Direct welding: Polyesterimide enameled wire does not need to remove the paint film and can be directly welded.

It should be noted that although the polyesterimide coating provides higher electrical insulation performance, it is easily hydrolyzed in the water-based sealing system. In water containing chloride ions, a significant voltage drop will occur, and the brittleness of the paint film will increase.

Due to its excellent high temperature resistance, 180 class polyesterimide enameled wire is widely used in motors, electrical appliances, instruments and other products with high heat resistance requirements.

• Heat-resistant motors: such as industrial motors and aerospace motors in high temperature environments.
• Dry-type transformers: Dry-type transformers used for power transmission and voltage conversion.
