AWG38-30 Insulated Copper Clad Aluminum Winding Wire is a winding material commonly used in electrical windings and electronic devices.

Insulated copper-clad aluminum winding wire consists of two main parts: the inner core is made of aluminum conductors, and the outer part is covered with a layer of copper as a protective layer. The aluminum conductor provides the advantage of lightness and relatively low cost, while the copper protective layer provides good electrical conductivity and corrosion resistance.

The surface of the conductor of the winding wire is covered with a layer of insulating material, usually a polymer (such as polyimide or polyamide). The purpose of the insulation is to prevent short-circuiting or current leakage between wires or between wires and other components.


The gauge of winding wire is usually expressed using the AWG (American Wire Gauge) standard; the smaller the AWG number, the larger the wire diameter. For example, an AWG 30 wire diameter is larger than an AWG 38 wire diameter. 4.

Winding wire is commonly used in electrical windings for electronic devices, inductors, transformers and motors. Due to its lighter weight and lower cost, insulated copper-clad aluminum winding wire can replace traditional copper winding wire in some applications where light weight and economy are required.

Insulated copper clad aluminum winding wire has some advantages over pure copper winding wire such as light weight, cost effectiveness and good electrical conductivity. However, due to the higher resistivity of aluminum, the resistance will be slightly higher as compared to pure copper wires. In addition, aluminum is susceptible to oxidation in some specific environments, so proper protection and insulation is critical to ensure consistent line performance.

Specific specifications and applications may vary depending on the manufacturer, product standards, and requirements of a particular industry. If you have a specific application requirement, it is recommended that you consult the relevant manufacturer or refer to the latest industry standards for more detailed and accurate information.
