Polyester-imide magnet wire
Polyester-imide magnet wire, also known as PEI magnet wire, is a type of magnet wire that is insulated with a coating made of polyester-imide. It is commonly used in various electrical applications where high-temperature resistance, thermal stability, and excellent electrical properties are required.
Insulation Material: Polyester-imide is a type of polymer-based insulation material that offers exceptional thermal and electrical properties. It is known for its excellent resistance to high temperatures, making it suitable for applications where the wire is exposed to elevated temperatures.
Thermal Class: Polyester-imide magnet wire is typically classified as Class 180 (H) based on its thermal rating. This means that it can withstand continuous operation at temperatures up to 180°C (356°F) without significant degradation of its insulation properties.
Electrical Properties: Polyester-imide magnet wire provides good electrical insulation and dielectric strength. It has high breakdown voltage and can effectively handle high voltage applications. The insulation material also offers excellent resistance to electrical stress and corona discharge.
High-Temperature Resistance: One of the main advantages of polyester-imide magnet wire is its ability to withstand high temperatures. This makes it suitable for applications such as motors, transformers, and generators that generate significant heat during operation.
Mechanical Strength: Polyester-imide magnet wire exhibits good mechanical strength and resistance to abrasion. It can withstand the mechanical stresses encountered during winding and operation.
Applications: Polyester-imide magnet wire is widely used in various electrical devices and equipment, including motors, transformers, generators, solenoids, and other electromagnetic devices. It is commonly found in automotive applications, industrial machinery, and high-temperature environments where reliable and efficient electrical performance is required.
