edgewise winding enamelled aluminum wire

May 26, 2023

As a mature technological achievement, edgewise winding enamelled aluminum wire is widely used in the power industry. However, with the large demand for copper, the global reserves of copper are sharply reduced, and may even be exhausted in the near future. Therefore, the cost of using copper as the main raw material is very high, and the density of copper is relatively large, hard to bend and wrap, and the weight is relatively heavy, Therefore, people need to find a substitute for copper to produce new enameled flat wire. One of the main new products in the market is edge wise winding enabled aluminum wire



It includes a paint film, the inner conductor of the paint film is copper-clad aluminum conductor, the outer layer of the copper-clad aluminum conductor is copper conductor, and the inner layer is aluminum conductor.

The inner core of the edgewise winding enamelled aluminum wire is aluminum conductor, and the outer part of the aluminum conductor is provided with two layers of paint film, the first layer is polyester imide paint film, and the second layer is heat-resistant polyester paint film. The inner core conductor of the enamelled flat wire is all aluminum conductor, saving 40-60% of the cost, and the density of aluminum is much smaller than that of copper, and the aluminum conductor is relatively soft. Therefore, the aluminum flat wire is very convenient in winding, saving time and labor, and the weight of the aluminum flat wire is relatively light, which is suitable for transportation and handling. At the same time, the conductive effect of the aluminum conductor is good, which is worth promoting.

Edgewise winding enamelled aluminum wire not only greatly reduces the cost, but also uses aluminum material as the inner conductor, which reduces the weight and facilitates the transportation. Because the density of aluminum is smaller than that of copper, and it is softer than that of copper, the aluminum flat wire is easy to wind, and its conductivity is very close to that of copper, so it is safe and reliable in use
