Light weight: The density of aluminum is relatively low, making double polyester enameled aluminum square wire lighter than copper wire of the same cross-section, suitable for applications requiring lightweight design.
Corrosion resistance: Aluminum has good corrosion resistance and can resist oxidation and corrosion to a certain extent, increasing the service life and reliability of the cable.
Good heat dissipation: Square wire provides a larger surface area to help improve heat dissipation in high-temperature applications.



Aluminum is a poor conductor of electricity compared to copper. The resistivity of aluminum is about 1.6 times that of copper, so the resistance of double polyester enameled aluminum square wire is higher. When designing a circuit, trace length, current loading, and resistive losses must be considered to ensure electrical requirements are met.

The conductor of the double polyester enameled aluminum square wire is insulated by two layers of polyester enameled layers. Enameled polyester insulation has good electrical insulation and heat resistance properties, protecting conductors from the external environment.

Double polyester enameled aluminum square wire is suitable for low voltage applications such as power tools, household appliances, lighting equipment, instruments and meters. They are generally used for internal wiring connections, providing power and signal transmission functions.

- Aluminum square wire is a poor conductor, so current loading and resistance requirements must be carefully considered when designing circuits to ensure that the wire can meet the electrical performance requirements of the device.
    - Aluminum square wire may suffer galvanic corrosion when in contact with other metals. Care should be taken to select appropriate connectors and adapters when connecting and terminating to avoid galvanic corrosion affecting the performance and reliability of the line.
    - When selecting and using double polyester enameled aluminum square wire, it is recommended to refer to relevant standards and specifications and consult with a professional electrical engineer or supplier to ensure that the selected wire is suitable for your specific needs and application requirements.

Double polyester enamelled aluminum square wire is often used for internal wiring connections of low-voltage electrical appliances and electronic equipment, such as power tools, household appliances, lighting equipment, etc. They are suitable for applications requiring lightweight, cost-effective designs and lower current loads.
