High-temperature resistant enameled winding wire, also known as enameled wire or winding wire, is a type of wire used in various electrical applications that need to withstand high temperatures. It is commonly used in electric motors, transformers, generators, and other devices that generate or utilize electrical energy.

Here are some key characteristics and considerations for high temperature resistant enameled winding wire:
Temperature rating: this type of wire is designed to withstand higher temperatures than standard wire. It is typically rated for temperatures around 200°C (392°F) or even higher, depending on the specific application and requirements.


Insulation: The enamel or insulating coating on the wire is made from materials that can withstand high temperatures without degrading. Common materials include various types of polymeric materials such as polyester, polyimide (also known as Kapton) and composites.

Thermal Stability: High temperature enameled wire is carefully designed to maintain its electrical and mechanical properties even at high temperatures. This includes maintaining proper insulation resistance, dielectric strength and mechanical integrity.

Sizes and Gauges: These wires come in a variety of sizes or gauges, just like regular wires. The choice of gauge depends on the current-carrying capacity, voltage and space constraints of the specific application.

APPLICATIONS: High temperature enameled winding wire is used in environments where temperatures are higher than standard wire can withstand. Examples include electric motors used in aerospace, automotive and industrial applications, as well as transformers and other electrical equipment subjected to high operating temperatures.

Coating Type: Depending on the application and temperature requirements, different types of enamel coatings can be used, such as polyester, polyimide or mica coatings.

Solderability: The ability to solder the wire without damaging the insulation is an important consideration. High-temperature wires are often designed to have good solderability at high temperatures.

Handling Precautions: Due to the nature of high temperature insulation, these wires are usually more brittle than standard wires. Care needs to be taken when installing and winding the wire to prevent the insulation from cracking or splintering.

Factors such as expected operating temperature, voltage, current, mechanical stress, and available space need to be considered when selecting high-temperature resistant enameled winding wire for a particular application. It is critical to select wire that meets the requirements of the application to ensure reliability and safety.
For enameled copper wires, LP Industries mainly produces UEW, EIW, EI/AIW and AIW enameled round copper wires. 
Enameled wires for electric vehicles are mainly 180-240 degree enameled flat wires.
