Semi-Finished Coaxial Cable – RG6 CU/48/CCA
1. Cable Structure (No Outer Jacket)
| Layer | Material | Approximate 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) | 48 strands Copper-Clad Aluminum (CCA), ~30–35% coverage | — |
| Outer Jacket | Not included (semi-finished format) | — |
Outer Diameter (semi-finished core): ~5.0 mm
Finished Cable OD (with jacket): ~6.6–7.0 mm (varies by jacket)
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Impedance | 75 ohms |
| Capacitance | ~54 pF/m |
| Velocity of Propagation | ~85% (FPE dielectric) |
| Attenuation @ 100 MHz | ~6.4–6.6 dB/100m |
| Shielding Effectiveness | Moderate (foil + 48-wire CCA braid) |
| Mechanical Strength | Good (solid copper core) |
3. Key Features
Solid Copper Conductor: Ensures excellent signal transmission and low resistance
48-Wire CCA Braid: Provides basic to moderate EMI protection while reducing cost
100% Foil Coverage: Protects against signal leakage
Customizable Jacket: Can be finished with PE (outdoor), PVC (indoor), LSZH, or dual-layer jackets as needed
4. Application Scenarios
Residential CATV and satellite distribution
Indoor/outdoor broadband networks
OEM and export markets requiring flexible jacket finishing
Projects that need a cost-balanced signal solution with moderate EMI protection
5. Limitations
Lower shielding compared to 64- or 96-wire braided versions
CCA braid less durable than copper or tinned copper in harsh environments
Outer jacket required for installation and protection
