The use of copper-clad aluminum can reduce network failures and prevent network personnel from "cutting in winter and cutting in summer" during maintenance (aluminum strip vertical or aluminum tube products). Since the thermal expansion coefficients of the copper inner conductor and the aluminum outer conductor of the cable are very different, in the hot summer, the aluminum outer conductor is stretched.
The inner conductor of the copper is relatively retracted, and the elastic contact piece in the F headstock cannot be fully contacted. In winter, the aluminum outer conductor shrinks more and the shielding layer falls off. When the coaxial cable uses a copper-clad aluminum inner conductor, the difference in thermal expansion coefficient between the aluminum outer conductor and the aluminum outer conductor is very small.
When the temperature changes, the cable core failure is significantly reduced, and the network transmission quality is improved. Generally speaking, the comprehensive performance of copper-clad aluminum conductors is better than that of pure copper conductors, which will save the cost to users. Industry insiders believe that the use of copper-clad aluminum wire in the wire and cable industry is also an excellent way to relieve current business pressure.
A bimetallic wire drawn from an aluminum wire and a layer of copper has the advantages of small specific gravity and good transmission performance. Especially suitable for the inner conductor of RF coaxial cable. Compared with pure copper wire, the density is higher. Pure copper is about 40%. The transmission characteristics are better than those of pure copper wire, and it is an ideal inner conductor for the branch wire of RF coaxial cable.
