Semi-Finished Coaxial Cable – RG8 CCS/64/AL (50Ω)
1. Detailed Construction
| Component | Specification |
|---|---|
| Inner Conductor | Solid Copper-Clad Steel (CCS), ~2.70 mm – strong tensile strength |
| Dielectric | Foamed Polyethylene (PE), ~7.20 mm – stable impedance, low capacitance |
| Shielding (Braid) | 64 strands of bare Aluminum (AL) wire – moderate EMI shielding (~60–70% coverage) |
| Outer Jacket | Not included – jacket-free format for downstream processing (PVC, PE, or LSZH optional) |
2. Typical Dimensions
| Component | Dimension |
|---|---|
| Inner Conductor Diameter | ~2.70 mm |
| Dielectric Diameter | ~7.20 mm |
| Braid Diameter (bare) | ~8.10 mm |
| Final Jacket OD (optional) | ~10.30–10.50 mm (if jacketed) |
3. Electrical & Mechanical Properties (Typical):
| Parameter | Value |
|---|---|
| Impedance | 50 ± 3 ohms |
| Capacitance | ~100 pF/m |
| Shielding Effectiveness | Moderate (~60–70% coverage) |
| Attenuation @ 100 MHz | ~6.3 dB/100 m |
| Braid Tensile Strength | Lower than CCA or CU braid |
| Operating Temperature | -20°C to +70°C |
4. Key Features
Economical: AL braid significantly reduces material cost
Lightweight: Easier handling and transportation
CCS Core: High mechanical durability for pulling and installation
Flexible Use: Semi-finished format allows custom jacketing and branding
5. Application Areas
Short- to mid-distance RF signal transmission
Non-critical radio or data communication setups
Budget-focused cable OEMs and reprocessing lines
Custom-labeled local extrusion and finishing
Comparison Table – Semi-Finished RG8 Variants
| Specification | RG8 CCS/64/AL | RG8 CCS/64/CCA | RG8 CCS/96/CCA |
|---|---|---|---|
| Impedance | 50 ± 3 Ω | 50 ± 3 Ω | 50 ± 3 Ω |
| Inner Conductor | Copper-Clad Steel (CCS) | Copper-Clad Steel (CCS) | Copper-Clad Steel (CCS) |
| Dielectric | Foamed Polyethylene (PE) | Foamed Polyethylene (PE) | Foamed Polyethylene (PE) |
| Shielding | 64-wire bare Aluminum (AL) | 64-wire Copper-Clad Aluminum (CCA) | 96-wire Copper-Clad Aluminum (CCA) |
| Shielding Coverage | ~60–65% | ~65–70% | ~85–90% |
| Shielding Quality | Basic | Moderate | High |
| Mechanical Strength | Low (soft aluminum braid) | Moderate | Stronger (due to more wires) |
| EMI Protection | Basic environments | Standard RF environments | High-interference environments |
| Weight | Lightest | Moderate | Slightly heavier |
| Cost | Lowest ($) | Medium ($$) | Higher ($$$) |
| Application Suitability | Cost-sensitive installations | Standard RF signal transmission | Long-distance / EMI-sensitive projects |
Conclusion Recommendations:
CCS/64/AL → Best for low-cost, short-run, low-interference environments
CCS/64/CCA → Good mid-range balance of cost and shielding
CCS/96/CCA → Best for strong shielding, moderate cost increase
