1, Coaxial cable weaving outer conductor: commonly used for the flexible cable of the radio frequency form. The advantage is relatively soft, and can be used for small-size cable and solid insulation, and air-insulated cable; the Defect is poor electrical properties, greater attenuation.
2, tubular conductor: advantage is low attenuation, good shielding, and good mechanical, moisture-proof, and sealing; Defect is flexible.
3, stranded conductor: in some entities insulated power cable of the radio frequency, sometimes used by multiple root flat copper wire made of twisted on the insulation and outer conductor, and then on the overlapping tied a layer of copper tape around the package as a mechanical and additional conductive layer. Stranded conductor outside electrical properties between the braided outer conductor and tubular conductor.
4, plating outer conductor: first use the method of chemical plating on the surface insulation wrapped in a layer of copper plating, after plating thickening. The good flexible structure, lightweight, good shielding, low attenuation, low noise.
