Cable can be classified into two main types according to different inner conducting materials:
pure cooper and copper clad aluminum.
Copper clad aluminum conductor is often referred to as: CCA conductor. The composite wire of copper clad aluminum first launched in Germany in 30 s of last century, and it was promoted in Britain, the United States, France and other countries, moreover it was widely used in various fields. The CATV cable of USA began to try to use copper clad aluminum wire in as early as 1968, and the consumption quantity is 30,000 tons per year. American states have now replaced the pure copper cable with copper clad aluminum (steel) cable. In recent years, China's CATV cable of copper clad aluminum also has begun to be used in a large number. Countries formulated the industry standard SJ/T11223-2000 in 2000, vigorously promoting the use of copper clad aluminum cables. At present, copper clad aluminum cable has been widely used in cable television in Shanghai, Guangzhou, Zhejiang, Liaoning and other places and it becomes more and more popular.

Copper clad aluminum cover copper on the surface of aluminum or aluminum alloy or steel alloy copper core and is drew to be born. The copper layer thickness is above 0.55 mm. Due to the characteristics of the skin effect on the conductor of the high frequency signal transmission, cable TV signal above 0.008 mm is transmitted on the surface of the copper layer. Moreover, copper clad aluminum inner conductor can completely meet the requirements of signal transmission whose properties of the signal transmission are consistent with copper body of the same diameter.
The insiders hold the view that it is also a good way to alleviate the pressure of the present enterprise that wire and cable industry adopts copper clad aluminum wire. The outside of aluminum wire is the bread a layer of copper and is made by the drawing of double metal wire. For small specific gravity as well as good transmission performance, it is particularly applicable to the inner conductor of the coaxial cable of the radio frequency. Compared with pure copper wire, its density of copper clad aluminum wire is about 40% of pure copper. And the transfer characteristic is better than that of pure copper wire. So, it is the most ideal inner conductor of the coaxial cable of the radio frequency branch line.
