Class 130 enameled copper wire is an enameled wire coated with a layer of enameled insulation that can withstand temperatures up to 130°C. UL (Underwriters Laboratories) is an organization that tests and certifies the safety of a variety of products, including wires and cables. If you are looking for high quality UL Listed Class 130 enameled copper wire, you should follow these steps:

Find Reliable Manufacturers and Suppliers: Find reputable enameled copper wire manufacturers and suppliers. You can start by researching online, consulting industry directories, or seeking advice from industry professionals.

Check for UL certification: When considering purchasing a specific enameled copper wire product, make sure it is UL certified. This certification ensures that the wire meets safety and quality standards. You can verify UL certification by looking at the product label or requesting documentation from the manufacturer.


Class 130 enameled copper wire refers to enameled wire with a thermal classification or temperature index of 130°C according to NEMA MW 1000. Enameled wire, also known as winding wire or enameled wire, is a copper wire covered with a thin layer of enameled insulation, which allows it to be used in a variety of electrical applications.

Characteristics of grade 130 enameled copper wire:
Temperature Class: The "Class 130" designation means the wire can withstand temperatures up to 130°C (266°F) without significantly degrading its electrical or mechanical properties. Therefore, it is suitable for applications with operating temperatures within this range.

Enamelled Insulation: Copper wire is coated with a layer of enameled insulation that provides electrical insulation between turns and prevents short circuits in electrical components or winding applications.

Conductivity: Copper is used as a core material due to its excellent electrical conductivity. Therefore, it is suitable for applications requiring efficient electrical conductivity.

Applications: Class 130 enameled copper wire is commonly used in a variety of electrical and electronic equipment and systems, including motors, transformers, solenoids, coils, relays and other components requiring moderate operating temperatures.

Standardization: Temperature ratings for enameled wire are defined by industry standards, such as those established by the National Electrical Manufacturers Association (NEMA) in MW 1000. Class 130 is one of these defined temperature classes.

Coating Type: Enameled insulation can come in different types such as polyester, polyurethane, polyesterimide and other variations. The choice of insulation type depends on the specific application and environmental factors.

Sizes and Gauges: Wires come in various sizes and gauges, which determines their diameter. The specific size you choose depends on your application's current-carrying capabilities and mechanical constraints.
