FAQ
Why is CCS-30% used for coaxial cable center conductors?
CCS-30% provides the optimal balance between conductivity and strength for coaxial cables. At RF frequencies, skin effect causes current to flow primarily in the copper cladding, making the steel core invisible to the signal while providing mechanical strength.
How does skin effect benefit CCS in coaxial applications?
At RF frequencies (typically 5 MHz to 1 GHz for CATV), skin depth is very small (typically less than 10 micrometers). Current flows almost entirely in the copper cladding, so the steel core doesn't affect signal transmission while providing structural support.
What is the attenuation difference between CCS-30% and solid copper?
CCS-30% typically shows 3-5% higher attenuation than solid copper at CATV frequencies. For example, at 1 GHz, CCS may have 14.6 dB/100m vs 14.0 dB/100m for copper - a minimal difference that is easily compensated in system design.
What coaxial cable types use CCS-30%?
CCS-30% is commonly used in RG-6, RG-59, RG-11, and similar coaxial cables for CATV, satellite TV, and broadband applications. It's the dominant choice for drop cables and distribution cables in cable television networks.
