Semi-Finished Coaxial Cable – RG11 CCS/64/CCA
1. Cable Construction (No Outer Jacket)
| Component | Material | Approximate Diameter |
|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS), Ø 1.63 mm | 14 AWG |
| Dielectric Insulation | Gas-injected Foamed Polyethylene (FPE) | ~7.24 mm |
| First Shield (Tape) | Bonded Aluminum-Polyester Foil (100%) | — |
| Second Shield (Braid) | 64 strands Copper-Clad Aluminum (CCA), ~40% coverage | — |
| Outer Jacket | Not included (semi-finished format) | — |
Outer Diameter (semi-finished core): ~7.8–8.0 mm
Finished Cable OD (with jacket): ~10.2–10.5 mm
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Characteristic Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (due to FPE insulation) |
| Attenuation @ 100 MHz | ~5.4–5.6 dB/100m |
| Shielding Effectiveness | Moderate (due to 64-wire braid + foil) |
| Tensile Strength | High (due to CCS conductor) |
3. Key Features
CCS Core: Superior mechanical durability, suitable for long-distance pulls
64-Wire CCA Braid: Strikes a balance between shielding performance and cost
Bonded Foil: Ensures 100% coverage for additional EMI protection
Semi-Finished Flexibility: Enables customized jacketing (PVC, PE, LSZH, UV-resistant, etc.)
Cost-effective Solution: Ideal for volume-based supply without sacrificing basic performance
4. Application Scenarios
Mid-grade CATV and broadband distribution systems
Satellite signal transmission in moderate EMI environments
OEM finishing operations for custom jacket and branding
Projects requiring good performance at a competitive price point
5. Limitations
Higher attenuation than solid copper types
Shielding is moderate – not ideal for high-interference or professional-grade broadcast applications
Outer jacket must be applied before installation
