Application
It is mainly used in manufacturing communication cable and radio cable.

Structures & performances
RF cable has the features of low attenuation, high power, less servicing, and so on. The external diameter of RF cable is generally thick. There are two kinds of inner conductor which can be used in producing RF cable. One is a copper pipe with a wall about 1mm. The other is copper clad aluminum wire with a diameter more than 5mm. While producing this copper clad aluminum wire, in order to actualize the metallurgical join, we should use the generatrix wire with the diameter more than 14mm.
