2UEW/155 is a specification of insulated copper wire, 0.2mm means the wire diameter is 0.2 millimeters; 2UEW insulated copper wire adopts polyurethane as insulation material. Polyurethane insulation has good electrical insulation properties, abrasion resistance and chemical resistance. It also has high heat resistance and can maintain stable electrical insulation properties at higher temperatures.

0.2mm indicates that the diameter of this insulated copper wire is 0.2 millimeters, which can also be expressed as 24 AWG (American Wire Gauge). The smaller the wire diameter, the smaller the cross-sectional area of the wire and therefore the corresponding increase in resistance.


155 is the temperature rating of 2UEW insulation, indicating a temperature resistance of 155 degrees Celsius. This means that the insulation can maintain its electrical insulation properties at temperatures up to 155 degrees Celsius. The choice of insulation class should be based on the temperature requirements and safety standards of the specific application.

2UEW/155 insulated copper wire is widely used for winding and connection in electronic equipment. It is commonly used in micro motors, inductors, transformers, solenoid coils, inductive components, and other applications that require high precision and heat resistance. The stable electrical and insulating properties of insulated copper wire make it ideal for many electronic devices.

When selecting 2UEW/155 insulated copper wire, factors such as current loading, voltage requirements, insulation class and environmental conditions need to be considered. Ensure that the insulated copper wire selected can withstand the expected current load and meet the electrical performance and safety requirements of the application.

2UEW/155 insulated copper wire is a copper conductor with polyurethane insulation, a wire diameter of 0.2 mm and a temperature resistance of 155 degrees Celsius. It is suitable for electronic equipment with high-precision windings and has good electrical insulation properties and heat resistance. When in use, the appropriate wire diameter and insulation grade should be selected according to the specific application requirements and standards, and the relevant installation and use guidelines should be followed.
