Semi-Finished Coaxial Cable – RG11 CCS/48/CCA
1. Cable Structure (No Outer Jacket)
| Component | Material | Approx. Diameter |
|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS), Ø 1.63 mm | 14 AWG |
| Dielectric Insulation | Foamed Polyethylene (FPE) | ~7.24 mm |
| First Shield | Bonded Aluminum-Polyester Foil (100%) | — |
| Second Shield (Braid) | 48-wire Copper-Clad Aluminum (CCA), ~30–35% coverage | — |
| Outer Jacket | Not included (semi-finished format) | — |
Outer Diameter (semi-finished core): ~7.8 mm
Outer Diameter (after jacket): ~10.2 mm (varies by jacket type)
2. Electrical Characteristics
| Parameter | Typical Value |
|---|---|
| Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (FPE insulation) |
| Attenuation @ 100 MHz | ~5.7–5.9 dB/100m |
| Shielding Effectiveness | Basic |
| Mechanical Strength | High (due to CCS conductor) |
3. Key Features
CCS Conductor: High tensile strength; suitable for long pull distances during installation
48-Wire CCA Braid: Economical shielding for basic interference environments
Bonded Foil: Provides complete coverage against signal leakage
Semi-Finished Format: Allows use of custom jackets such as PVC, PE, LSZH, UV-resistant, or dual-layer
4. Common Applications
Cost-sensitive CATV and satellite systems
Long-distance signal distribution in low-EMI environments
OEM production lines for finishing with region-specific jackets
Bundled coaxial solutions or private-label contracts
5. Considerations
Higher attenuation and lower shielding compared to CU or higher braid versions
Not recommended for EMI-heavy environments or high-bandwidth, critical signal paths
Must be jacketed before use to meet installation and safety standards
