We produce magnet wire products like rectangular enameled wire, CCA wire, etc. Here we are discussing CCA wire. CCA wire and copper wire, what choice will you make?
CCA Wire is formed by concentrically cladding a copper layer on the surface of an aluminum or aluminum-steel alloy core material, which is drawn, and the thickness of the copper layer is above 0.55mm. Due to the skin effect characteristics of high-frequency signal transmission on the conductor, the cable TV signal is transmitted on the surface of the copper layer above 0.008mm. The copper-clad aluminum inner conductor can fully meet the signal transmission requirements, and its signal transmission characteristics are comparable to those of copper with the same diameter. The body is consistent.
In general, the overall performance of copper-clad aluminum conductors is better than pure copper conductors, which will save users' costs. The industry believes that the use of copper-clad aluminum wire in the wire and cable industry is also a good way to relieve the current pressure on enterprises. The aluminum wire is covered with a layer of copper and made of bimetallic wire. Because of its small specific gravity and good transmission performance, it is especially suitable for the inner conductor of radio frequency coaxial cable. Compared with pure copper wire, its density is About 40% pure copper. The transmission characteristics are better than pure copper wire, and it is the most ideal internal conductor of radio frequency coaxial cable branch line.
