UEW copper round insulation wire also called UEW Polyurethane Cu Enamelled Winding Wire, 3UEW, 2UEW,1UEW.

When using UEW copper round insulation wire, it is essential to consider the application requirements and ensure that the wire's specifications align with the desired electrical properties, temperature range, and current-carrying capacity.
Heat Resistance Grades: 130°C (B Class), 155°C (F Level), 180°C (H Level) 
UEW Solderable Enamelled Copper Wire 

What is UEW?
UEW is one of wire enamels are applied on copper and aluminum round and flat wires used in motors, transformers, generators and electrical measuring instruments. They are cured onto the wires with heat. 

What is wire enamel? Wire enamels are applied on copper and aluminum round and flat wires used in motors, transformers, generators and electrical measuring instruments. They are cured onto the wires with heat. The resulting coating’s main function is electrical insulation. Wire enamels are also described as primary insulation.

What is the difference between polyurethane-180 and polyester-imide magnet wire?Polyurethane-180 combines the thermal properties of a class 180°C insulation, while offering low temperature solderability at 390°C (24 AWG and finer). Automotive relays, ignition coils, transformers and solenoids. Polyester-imide magnet wire is insulated with a Class H modified polyester resin.
