The resistance of EI enameled copper round wire is measured at different elongation percentages. The maximum elongation value is at 0.75 mm, while the minimum elongation value is at 0.5 mm. The resistance at 20 degC must be within the range of Appendix C. The elongation at break of the conductor should not be less than Table 4, and four out of five samples of nominal conductor diameter of 0.100 mm and below must not break at the voltages listed in Table 8.
The Class 200 Polyesterimide EI enameled copper wires are overcoated with polyamide-imide. They have excellent refrigerants and heat shock resistance. They are suitable for high-speed winding and electrical applications in refrigeration and air conditioning compressors, microwave oven electric instruments, and other pressurized motors. The corrosion resistance of these wires is higher than that of ordinary copper wire.
The high temperature resistance and high voltage insulation properties of EI enameled copper round wire make it an ideal choice for motors and transformers. The wire is available in various radii. The 0.75 mm radius was found to be the best choice for insulated motors. However, the conductor radius is not the only factor to consider when choosing an EI type. If the insulating value is a critical factor, you can check the insulation breakdown voltage and lifetime by using a thermal analyzer.
Another type of EI wire is polyamide-imide (PAI) coated. Its resistance to heat and refrigerants makes it ideal for winding and electrical devices. This wire is primarily used in electromagnetic coils, magnets, and transformers. During production, it is covered with a protective layer of insulation, typically one to four layers of a polymer film. This shield prevents electrical currents from reaching the conductor, thereby extending the life of the wire.
The electrical properties of EI round copper wire include a high electrical conductivity. It is 40% lighter than copper wire and a good alternative for insulated cables. It is also resistant to heat and abrasion. It can be used in electric motors. It is ideal for twisted-coil applications. The smallest radii are best for bare wire.

The main difference between enameled copper wire and bare copper is the thickness of the enamel film. The thicker the enamel, the better. These wires have a higher resistance to heat and are often used in electric motors. Aside from converting electrical energy to mechanical motion, EI round copper wire is also used in electric motors. For example, an electric motor converts electrical energy into motion by using magnetic fields. An elongated and asymmetrical magnet can be more efficient.
The EI enameled copper round wire is a type of wiring consisting of a copper conductor covered with a polymer film. It is primarily used in electric motors and transformers. Its radii range from 0.50 to 1.50 mm. The smallest wires can be twisted up to a half-meter. This type of wiring can be very durable and resists heat and abrasion.
EI enameled copper round wire is a common electrical conductor. It is often referred to as magnet wire or winding wire. Its primary application is in the transference of electrical energy. Its high conductive properties make it an ideal material for winding and magnetic coils. The insulation layer protects the wire from electrical currents and improves its life span. The two main advantages of this electrical conductors are their low weight and excellent resistance.
Its durability is the hallmark of EI enameled copper round wire. The EI coating is composed of a polymer film over a copper conductor. The enameled wires are made of two-wire materials, which are both highly conductive and flexible. In addition, they can also be molded into other shapes. They can be shaped in many ways. For example, they can be bent to be used as an electromechanical connector.
A single-stranded EI wire can be 50 mm thick. The enamel coating is applied to the conductor's circumference and its diameter. The EI wires are also available with a diameter of 0.75 mm and a length of 1.49 mm. This electrical conductor is a popular material for a variety of applications. The high quality of these copper wires makes them an attractive choice for a wide range of electrical circuits.
