Copper-clad aluminum enameled wire can be used for signal transmission, but now it is used for power transmission, which is prone to problems, and the service life of its products will be greatly reduced. In fact, in the use of copper-clad aluminum enameled wire, pay attention to the oxidation protection of the cut surface of the enameled wire to ensure the effective combination of copper and aluminum, which can be used for a long time.

Copper-clad aluminum wire and copper-clad aluminum enamelled wire are actually unusable in many fields, but in fact many companies are using them for transformers, which is very worrying. There are two concerns about the use of copper-clad aluminum wires. The resistivity of copper-clad aluminum wires is higher than that of copper with equal cross-sections, and the problem of temperature rise; the easy oxidation of aluminum wires will further increase the resistance of wires, and measures to prevent oxidation.

The most worrying thing is the copper-aluminum bond in the copper-clad aluminum wire, the metallurgical bond that is often said in the industry, the real reliability in the long-term use process, and whether the copper-aluminum bonding ability can pass through the process of thermal expansion and contraction. Can stand the test, there is no real demonstration in the industry.
