- LIGHTWEIGHT: The relatively low density of aluminum makes double-enameled polyester enameled aluminum square wire lighter than copper wire of the same cross-sectional area, making it suitable for applications requiring lightweight design.
   - CORROSION RESISTANCE: Aluminum has good corrosion resistance and is able to resist oxidation and corrosion to a certain extent, increasing the life and reliability of the cable.
   - Good heat dissipation: Square wire provides a larger surface area, which helps to improve heat dissipation performance for high temperature applications.

Aluminum has poor electrical conductivity properties compared to copper. The resistivity of aluminum is about 1.6 times higher than that of copper, so double enameled polyester enameled aluminum square wire has a higher resistance. When designing circuits, line length, current loading and resistance loss need to be considered to ensure that electrical requirements are met.

The conductors of double enameled polyester enameled aluminum square wire are insulated with two layers of polyester enamel. The polyester enameled insulation has good electrical insulation and heat resistance, and can protect the wire from external environmental interference.


Double Enameled Polyester Enameled Aluminum Square Wires are suitable for low voltage applications such as power tools, household appliances, lighting equipment, instruments and meters. They are usually used for internal wiring connections, providing power transmission and signal transmission functions.

- Aluminum square wires have poor electrical conductivity, so careful consideration of current loading and resistance requirements is needed when designing circuits to ensure that the wires can meet the electrical performance requirements of the equipment.
   - Aluminum square wires may have problems with galvanic corrosion when in contact with other metals. Care needs to be taken in the selection of appropriate connectors and adapters when connecting and terminating to prevent galvanic corrosion from affecting the performance and reliability of the line.
   - When selecting and using double-enameled polyester enameled aluminum square wire, it is recommended that you refer to the relevant standards and specifications and consult a professional electrical engineer or supplier to ensure that the wire selected is suitable for your specific needs and application requirements.

Double-enameled polyester enameled aluminum square wires are commonly used for internal wiring connections of low-voltage electrical and electronic equipment, such as power tools, household appliances, and lighting equipment. They are suitable for applications requiring lightweight design, economy and lower current loads.
