Co-axial cables are used for transmitting high-frequency electrical signals with low losses. Cable is used in a variety of applications, including telephone trunk lines, high-speed computer data buses, cable television signals, and radio transmitters and receivers connected to antennas. ZENFLEX RG-6 comes with center conductor of copper, shielded with gas injected physical foam, dielectric Poly-laminated aluminium tape is applied with sufficient overlap longitudinally over the foam dielectric. The second shield is of aluminium braiding with high tensile strength. Finally, outer sheathing is done of FR PVC.
HOW DO CO-AXIAL CABLE WORKS?
Co-axial cables are mainly built up of these four different layers:
1. A centre conductor, which is usually a copper wire, through which data and video travel through
2. Surrounding the copper wire is a dielectric plastic insulator.
3. A braided mesh made from copper/alloy then helps to shield the cable from electromagnetic interference (EMI).
