Thermal class 220 aluminium winding wire also known as aluminum magnet wire or enamelled aluminum wire, is a type of electrical conductor used in various applications, including motors, transformers, and generators. It is made by coating the aluminum conductor with a thin layer of insulation, typically made of a polymer such as polyester or polyurethane, to provide electrical insulation and protection.

Thermal Class 220 refers to the maximum operating temperature of an electrical insulation system. It indicates that the insulation material used in the wire is designed to withstand temperatures up to 220 degrees Celsius (428 degrees Fahrenheit) without significant degradation.

Diameter. 0.2-10.0mm. 
Conductor Material: Aluminum. 
Color: Brown. 
Thermal class. 155-220 Deg C.

When a thermal Class 220 insulation system is used with aluminium winding wire, it means that the wire is suitable for applications where the operating temperatures can reach up to 220 degrees Celsius. The thermal class rating ensures that the wire's insulation can withstand the heat without deteriorating, which is important for maintaining the wire's electrical performance and preventing insulation breakdown.

It's worth noting that while the insulation system may be rated for 220 degrees Celsius, the actual temperature at which the wire can operate safely depends on various factors such as the design, installation, and specific application requirements. It is essential to consult the manufacturer's guidelines and consider the specific conditions in which the wire will be used to ensure proper and safe operation.
