Semi-Finished Coaxial Cable – RG8 CCS/96/CCA (50Ω)
1. Detailed Construction:
| Component | Material / Description |
|---|---|
| Inner Conductor | Solid Copper-Clad Steel (CCS), Ø ~2.70 mm – provides high tensile strength for pulling |
| Dielectric | High-performance Physical Foamed Polyethylene (PE) – low dielectric constant, Ø ~7.20 mm |
| Shielding (Braid) | 96 strands of Copper-Clad Aluminum (CCA), approx. 85–90% coverage – enhanced EMI blocking |
| Jacket | Not included – user can apply PVC, PE, or LSZH based on final application |
2. Typical Dimensions (Semi-Finished Stage)
| Specification | Value |
|---|---|
| Inner Conductor Diameter | ~2.70 mm |
| Dielectric Diameter | ~7.20 mm |
| Braiding Diameter (bare) | ~8.20 mm |
| Final Jacket OD (after jacketing) | ~10.30–10.50 mm |
3. Performance Characteristics (Approximate)
| Electrical Property | Typical Value |
|---|---|
| Impedance | 50 ± 3 ohms |
| Capacitance | ~100 pF/m |
| Velocity of Propagation | ~82% (depends on PE type) |
| Attenuation @ 100 MHz | ~6.1 dB/100 m |
| Attenuation @ 400 MHz | ~13.0 dB/100 m |
| Operating Temperature Range | -20°C to +75°C (bare) |
4. Advantages
Higher shielding with 96-braid CCA reduces signal interference in noisy environments
Cost-effective alternative to pure copper while maintaining strong signal integrity
Semi-finished format provides flexibility for OEMs: local jacketing reduces shipping costs
Strong mechanical durability thanks to CCS core—ideal for installation over long runs
5. CCS/64/CCA vs. CCS/96/CCA vs. CU/96/CCA
| Parameter | RG8 CCS/64/CCA | RG8 CCS/96/CCA | RG8 CU/96/CCA |
|---|---|---|---|
| Impedance | 50 Ω | 50 Ω | 50 Ω |
| Inner Conductor | CCS (Copper-Clad Steel) | CCS (Copper-Clad Steel) | CU (Pure Copper) |
| Conductor Diameter | ~2.7 mm | ~2.7 mm | ~2.7 mm |
| Dielectric Material | Foamed PE | Foamed PE | Foamed PE |
| Shielding Type | 64-braid CCA (Copper-Clad Aluminum) | 96-braid CCA (Copper-Clad Aluminum) | 96-braid CCA (Copper-Clad Aluminum) |
| Shield Coverage | ~60–70% | ~85–90% | ~85–90% |
| Mechanical Strength | Moderate | Moderate | Lower than CCS |
| Signal Attenuation | Medium | Lower than 64-braid | Lowest (best performance) |
| Cost Level | $ (Lowest) | $$ (Balanced) | $$$ (Highest) |
| Corrosion Resistance | Medium | Medium | High |
| Flexibility | Moderate | Slightly stiffer | Slightly softer |
| Target Use Case | Entry-level RF systems | Mid-range/professional RF systems | High-end RF or broadcast systems |
Summary:
✅ Choose CCS/64/CCA if cost is your top concern and moderate shielding is acceptable.
✅ Choose CCS/96/CCA for a balanced option with better EMI protection at a reasonable price.
✅ Choose CU/96/CCA when signal quality and durability are the highest priority, despite the higher cost.
