Semi-Finished Coaxial Cable – RG6 CU/64/CCA
1. Cable Structure (No Outer Jacket)
| Component | Material | Approx. Diameter |
|---|---|---|
| Inner Conductor | Solid Copper (CU), Ø ~1.02 mm | 18 AWG |
| Dielectric Insulation | Gas-injected Foamed Polyethylene (FPE) | ~4.57 mm |
| First Shield (Foil) | Bonded Aluminum-Polyester Tape (100%) | — |
| Second Shield (Braid) | 64 strands Copper-Clad Aluminum (CCA), ~40–45% coverage | — |
| Outer Jacket | Not included (semi-finished format) | — |
Outer Diameter (core only): ~5.0 mm
Final OD (with jacket): ~6.8–7.2 mm (depending on jacket)
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Impedance | 75 ohms |
| Capacitance | ~54 pF/m |
| Velocity of Propagation | ~85% (FPE dielectric) |
| Attenuation @ 100 MHz | ~6.1–6.3 dB/100m |
| Shielding Effectiveness | Moderate to Good |
| Mechanical Strength | Strong (due to solid copper core) |
3. Key Features
Solid Copper Conductor: Delivers superior signal quality and low attenuation
64-Wire CCA Braid: Provides a good balance of EMI protection and material cost efficiency
100% Aluminum Foil Shielding: Ensures continuous coverage for RF shielding
Jacket-Free Core: Allows flexible finishing (e.g., PE jacket for outdoor use, LSZH for fire-rated indoor environments)
4. Application Scenarios
CATV backbone and feeder cables
Satellite signal distribution in commercial and residential environments
OEM and contract manufacturing for local markets
Hybrid or bundled cable applications requiring moderate EMI shielding
5. Considerations
Less shielding than 96-braid cables, but better than 48-braid
CCA braid is more economical but less durable than tinned copper in repeated bending
Requires jacket application before field use to ensure environmental protection and compliance
