Semi-Finished Coaxial Cable – RG11 CCS/96/CCA
1. Cable Structure (No Outer Jacket)
| Layer | 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 | Bonded Aluminum-Polyester Foil (100%) | — |
| Second Shield (Braid) | 96 strands Copper-Clad Aluminum (CCA), ~60–65% coverage | — |
| Outer Jacket | Not included (semi-finished cable) | — |
Outer Diameter (semi-finished core): ~7.8–8.0 mm
Final OD (after jacket): ~10.2–10.5 mm (depends on jacket material)
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Characteristic Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (FPE insulation) |
| Attenuation @ 100 MHz | ~5.1–5.3 dB/100m |
| Shielding Effectiveness | High (due to 96-wire braid + foil) |
| Mechanical Strength | Excellent (thanks to CCS core) |
3. Key Features
CCS Inner Conductor: Provides high tensile strength for long installations or outdoor pulls
96-Wire CCA Braid: Offers strong EMI protection while reducing weight and material cost
Bonded Aluminum Foil: Ensures 100% shielding continuity
Semi-Finished Core: Enables OEMs to apply:
PVC, PE, LSZH, or dual jackets
Color-coded or fire-resistant sheaths for local market needs
4. Application Scenarios
Broadband mainlines and CATV feeder networks
Satellite systems requiring long cable runs
Outdoor or underground applications (after finishing)
OEM or contract manufacturing with regional labeling and certification needs
5. Considerations
CCS has higher attenuation than pure copper, but acceptable in most use cases
CCA braid offers good shielding, but lower durability than full copper
Requires outer jacket before final use
