Round enameled AWG 28 copper wire is a common wire used in a variety of electronic devices and applications.AWG 28 indicates that it is a copper wire manufactured to U.S. Wire Gauge standards.AWG 28 is a thinner gauge, with a diameter of approximately 0.32 mm (0.0126 inches).

AWG 28 copper wire has a relatively low current carrying capacity due to its small diameter. The current carrying capacity depends on the cross-sectional area of the wire, and thinner copper wires have a smaller cross-sectional area, so they are limited in the amount of current they can transmit. When selecting AWG 28 copper wire, you need to make sure that its current-carrying capacity can meet the requirements of the application and avoid exceeding its rated current-carrying capacity.

AWG 28 copper wire has a smaller diameter and therefore has a higher resistance. Higher resistance results in increased energy loss and heat generation. In long distance transmissions or applications that are more sensitive to resistance, it may be necessary to consider the effects of resistance and select thicker wire to minimize resistance.



Round enameled copper wires typically have an insulating enamel coating that is used to provide electrical insulation and protect the wire. The selection and quality of the insulating enamel material is critical to ensuring the safety and reliability of the wire. Common insulating materials include polyamides (e.g., polyamidates) and polyalcoholates (e.g., polyurethane amides). These materials have good heat resistance and insulation properties and can meet the requirements of many applications.

AWG 28 copper wire is typically softer and more flexible due to its smaller diameter. This gives it an advantage in applications where it needs to be bent or installed in tight spaces. Flexible wire is easy to route and connect and accommodates a wide range of installation needs.

When selecting and using AWG 28 copper wire, follow applicable standards and codes, such as those of the National Electrical Manufacturers Association (NEMA). These standards provide guidance on wire specifications, electrical characteristics, and safety to ensure that the copper wire selected meets the relevant requirements.

Specific applications and requirements may vary, so when selecting wire, it is recommended that you refer to the relevant specifications and consult with a professional engineer to ensure that the AWG 28 copper wire selected is suitable for your particular application and meets safety, performance and reliability requirements.
