Nowadays, enameled aluminum wire is used more and more, and the use of enameled aluminum wire is inseparable from its performance. In addition to the advantages of copper enameled wire, it also has great advantages in net weight and cost. The following is the main reason why enameled aluminum wire is popular:
1. Enameled aluminum wire has high-temperature resistance, good thermal shock and softening and penetration performance, suitable for high-speed automation technology to wrap the wire, and also has high breakdown field strength, no pinholes, direct welding, high-frequency resistance, medium With the characteristics of small electric loss angle, its single-pulse service life can be dozens of times that of general composite enameled wires.
2. The high-temperature resistance level of enameled aluminum wire is usually higher than that of copper enameled wire by about 20°C; while the copper conductor is changed to the aluminum conductor, only the conductor diameter must be increased by 14.7%, and the other main performance parameters are not changed; The key is that the original one ton of copper enameled wire, it only needs 0.4 tons to change to the enameled aluminum wire, and the cost is about 20% of the copper enameled wire.
