1. ECCA wire can be used for signal transmission, but now it is used for power transmission. The question is very simple. The service life of its products will be greatly shortened. In fact, in the application of ECCA Wire, it can be used for a long time to pay attention to the oxidation and maintenance of enameled wire parts and ensure effective contact between copper and aluminum.
2. Many kinds of copper-clad aluminum wire and copper-clad aluminum paint cannot be used in practice, but in fact many companies are using transformers, which is very worrying. There are two problems with using ECCA wire. The resistivity of the conductor itself is higher than that of copper with equal cross-section, and the temperature rise is questionable. The easy oxidation of aluminum wire will further increase the resistance of the wire and prevent oxidation.
3. People are worried about the connection between copper and aluminum in ECCA wire. Metallurgical connections frequently used in industry are true reliability in long-term applications. In the process of expansion with heat and contraction with cold, whether the copper-aluminum connection can withstand the test has not been confirmed by the industry.
