Identification method of Enameled Copper Clad Aluminum Wire:
Most enameled copper clad aluminum wire is soft copper wires, and the identification method is very simple. One end of the copper wire is burned by the external flame of the lighter, because the melting point of the aluminum wire is lower than the melting point of the copper wire, so if the copper-clad aluminum wire is used, the part burned by the flame will quickly become ashes, leaving nothing behind. However, after pure copper burns, the copper wire shrinks rapidly, leaving a small ball on the wire head.
Comparison of enameled copper clad aluminum wire;
Compared with pure copper wire, the enameled copper clad aluminum wire has the advantages of good conductivity, lightweight, obvious economic benefits, flexible construction, easy operation, etc. The length ratio of the same steel wire under the weight of warp yarn is 2.45: 1, so purchasing 1 ton of copper-clad aluminum wire is equivalent to purchasing 2.45 tons of pure copper wire, which has the great advantage of saving cost.
Compared with pure aluminum wire, enameled copper clad aluminum wire has higher conductivity, enhanced tensile strength and elongation, and good weldability: copper-clad aluminum wire has the same weldability as pure copper wire because its surface is concentrically coated with a layer of pure copper, thus greatly improving the mechanical properties and applicability of the product.
