Brand holderEnamelled wire, also known as magnet wire or winding wire, is a type of wire used in the construction of electrical components, such as transformers, motors, and coils. The temperature rating or thermal class of enamelled wire indicates the maximum temperature that the wire's insulation can withstand without degrading over time.
The temperature rating of enamelled wire is typically expressed using a letter code, such as:
-
F (155°C): This is a common temperature rating for enamelled wire. It means that the wire's insulation can withstand a continuous operating temperature of up to 155 degrees Celsius (311 degrees Fahrenheit).
-
H (180°C): Enamelled wire with an H rating can withstand temperatures up to 180 degrees Celsius (356 degrees Fahrenheit).
-
N (200°C): N-rated enamelled wire can handle continuous operating temperatures up to 200 degrees Celsius (392 degrees Fahrenheit).
-
C (220°C): Enamelled wire with a C rating can withstand temperatures up to 220 degrees Celsius (428 degrees Fahrenheit).
-
Other Ratings: There are other temperature ratings available, such as 130°C and 240°C, depending on the specific application and insulation material.
It's crucial to select enamelled wire with an appropriate temperature rating for your application to ensure that the insulation does not degrade or melt when the wire is subjected to its maximum operating temperature. Using wire with a higher temperature rating than necessary is generally a good practice to provide a safety margin and prevent insulation failure due to overheating.
Additionally, always follow the manufacturer's specifications and guidelines for the enamelled wire you are using, as they may provide specific temperature ratings and usage recommendations for their products.
