Three Points When Use Copper Clad Aluminum Wire(2)

2, The copper clad aluminum wire and enameled copper clad aluminum wire can be not used in many categories practically. But the fact that many companies which make transformers are used. It is very worried. There are two concerns about the copper clad aluminum wires’ use.One concerns is temperature rise, because its cross-section copper resistivity ratio is higher than copper wire.The other concern is that aluminum wire is so easily to be oxidizable that conductor resistance will further increase.

3, The most worrying is the contact between copper and aluminum in copper clad aluminum wire.The reliability of copper and aluminum contact which metallurgy industry sector often said can not be proven true.And whether copper and aluminum contact can be tested in the process of reliability in the process of thermal expansion and contraction.
