Popular application and classification of enameled wire

Polyimide Kapton Covered Enameled Aluminum Wire Strip is a multi-layer polyimide & fluoropolymer dispersion-coated film. The fluoropolymer coating functions as a heat-fusible layer for bonding to magnet wire conductors. It has superior scrape abrasion resistance and exhibits lower frictional properties than wire insulated with other commonly used polyimide materials. Polyimide film aluminum wire is ideal for demanding magnet wire applications and for difficult-to-wind motors.

Glass-fiber covered aluminum magnet wire used to have weak coating strength (abrasion resistance, shock resistance, and flexibility). However, that disadvantage has been significantly improved recently by refining material selection and manufacturing methods. The demand for glass-fiber covered aluminum magnet wire is increasing as the wires have excellent uniformity and electrical properties under high temperatures and humidity.

Kapton insulated aluminium wires are suitable for both HV and UHV applications at temperatures ranging from -269 to 200¡ãC with maximum bakeout temperature of 260¡ãC.
Kapton insulated aluminum wire is designed for use in high & ultra-high vacuum applications. Kapton has high mechanical strength, excellent electrical insulation properties, and low outgassing rates making it ideal for use as an in-vacuum insulator. These wires can be utilized in temperature ranges from 4K to 260¡ãC.

Winding wires used in electrical equipment are usually called magnetic wires. In other words, “magnetic wires are used to exchange electrical energy and magnetic energy.” Magnetic wire is roughly divided into enameled wire (insulation coated) and coated wire (fiber/film insulation) and their combinations. The two types of magnetic wires and their performance are very different. ASTM (American Society for Testing and Materials) B193, no more than 0.017241 ohm (square millimeter/meter), the film or coating should meet the latest version of ANSI, ASTM or NEMA applicable standards, and modify the specified resin. The modified resin is Chemically changed resin, or containing one or more additives to retain the basic chemical characteristics of the original resin to enhance certain performance or application characteristics, the coated conductor needs to meet all the required test requirements of the appropriate NEMA standard (UL certification project) .

According to the characteristics and uses of insulation, winding wires can be divided into four categories: enameled wires, wrapped wires, special winding wires, and inorganic composite winding wires.

¡ñ Conductor resistance. Measure with a conductor resistance tester, and then change to the value at 20¡ãC for comparison.
¡ñInsulation destruction voltage. Twist two enameled wires, apply voltage between the conductors, and judge by the damage voltage of the paint film. This performance is analyzed and judged through two tests of normal state and cold state breakdown voltage.
¡ñPaint film continuity (pinhole). Check the small holes of the paint film with a certain length of the test material. The project is tested by a high-pressure paint film continuity tester.

The selection criterion of the electromagnetic wire is not considered for resistance, as the problem of resistance and fever can be done by selecting the same cross-sectional wire, it is the main consideration of the thick wire or the thin wire is mainly considered Operability.

Heat resistance refers to the properties of a substance that can maintain its excellent physical and mechanical properties under heated conditions. The highest use temperature of commonly used materials to characterize. There are different standards and test methods for different materials. Such as plastics are generally expressed by Martin heat-resistant temperature. The coating industry uses a blast constant temperature oven or a high temperature furnace. After it reaches the specified temperature and time, the surface condition of the paint film is inspected, tested, or other properties such as impact, bending, water immersion, salt spray test, etc., and then before and after Test data representation. All coatings used in higher temperature occasions must use heat resistance as an important technical indicator of the coating film
