The use of copper clad aluminum wire is influenced by many factors, including the usage environment, cable quality, installation quality, maintenance, load conditions, as well as the size and power loss of the wire.

In general, the service life of copper clad aluminum wire is between 15 and 35 years. In special environments such as humidity, high temperature, and high altitude, its service life may be shortened. When used without load, the lifespan of copper clad aluminum wire can reach about 50 years, but its lifespan will be relatively short under frequent starting and stopping loads, electrostatic field strength, and external stress.

Overall, the general lifespan of copper clad aluminum wire is around 15 to 20 years. To ensure safe and reliable long-term use, it is recommended to inspect copper clad aluminum wires every 10 years and replace them if necessary.
