The names of Enameled Copper Clad Aluminum Wire and enameled copper wire are not different, but their performances are quite different. We all know that copper enameled wire is made of copper material, so what help does the upgrade of enameled copper clad aluminum wire bring us? Let's get to know each other.
First of all, we have to understand what is the inner conductor of enameled copper clad aluminum wire, which is the raw material of copper-clad aluminum, and what is copper-clad aluminum. Copper clad aluminum is a new type of electromagnetic wire, which separates the excellent conductivity of copper from the lightweight of aluminum, and its characteristics are between copper and aluminum. Enameled copper clad aluminum wire is widely used in transformers, inductive electromagnetic coils, acoustic coils, electromagnetic wires for degaussing coils, etc. It has high DC resistivity, lightweight and good solderability. But at the same time, there are also several aspects that need attention.
Due to the low cost, most enterprises use enameled copper clad aluminum wire in power transmission and transformer, and enameled copper clad aluminum wire cannot be used in many fields in practice. The resistivity of enameled copper clad aluminum wire is higher than that of copper wire, so the problem of temperature rise is worth paying attention to. In addition, aluminum wire is easy to oxidize, which will further increase the resistance. Measures to avoid oxidation are required to prevent losses from forming during application. The enameled copper clad aluminum wire can be used for signal transmission, but it will cause great problems in power transmission and reduce the service life of its products. During application, attention should be paid to maintaining the section of enameled wire to avoid aluminum oxidation and ensure the effective separation of aluminum and copper, which can also prolong the service life. What needs to be paid attention to most is the reliability of this new type of metallurgical separation electromagnetic wire in the long-term application process. In the process of thermal expansion and cold contraction, the copper aluminum separation can stand the test, and there is no real demonstration in the industry.
In any case, enameled copper clad aluminum wire still has many advantages such as low cost, lightweight and poor conductivity. Reasonable application and protection can prolong the service life and greatly reduce the cost.
