Semi-Finished Coaxial Cable —RG7 CU/96/CCA
1.Cable Structure
| Layer | Specification |
|---|---|
| Inner Conductor | Solid bare copper (CU), Ø ≈ 1.13–1.20 mm |
| Dielectric Insulation | Gas-injected or solid foamed polyethylene (FPE), Ø ≈ 5.0–5.3 mm |
| First Shield | Aluminum foil, bonded 100% to the dielectric (for internal shielding) |
| Second Shield | 96-wire braided shield, made of CCA with ≥95–98% coverage |
| Outer Jacket | Not included – for final extrusion by the customer |
Optional features include water-blocking gel, ripcords, or steel messenger wire for aerial applications.
2. Electrical & Transmission Performance
| Parameter | Typical Value (@100 MHz) |
|---|---|
| Characteristic Impedance | 75 ± 3 ohms |
| Capacitance | ≈ 53 – 55 pF/m |
| Velocity of Propagation | ≥ 85% |
| Return Loss | ≥ 20 dB |
| Attenuation @100 MHz | ≤ 7.5 dB/100m |
| Shielding Effectiveness | ≥ 50–60 dB |
| DC Resistance (Inner Cond.) | ≤ 21.0 ohms/km |
3.Key Advantages
1. Premium Shielding for Critical Installations
96-wire braid delivers maximum shielding efficiency against EMI and signal leakage
Ensures high signal-to-noise ratio (SNR) over long distances or in high-interference environments
2. Solid Copper Core for Reliable Transmission
Maintains low attenuation, stable resistance, and consistent propagation delay
Suitable for analog/digital signals: TV, SAT, broadband, CCTV
3. Ready for CPR, Indoor, or Outdoor Jacketing
Designed for extrusion with:
LSZH jackets for CPR B2ca/Cca/Dca cables
PE for UV- and water-resistant outdoor applications
PVC for general use and affordability
4. Rugged and Mechanically Resilient
High braid density adds tensile strength, reduces physical deformation, and improves cable longevity during installation
4.Supply Format
| Item | Specification |
|---|---|

6.Customization Options
Dielectric: Low-density foam for lower capacitance and higher velocity
Braiding Pitch: Adjustable for extrusion and shield impedance matching
Drain Wire: Optional, for grounding continuity (required in some CPR classes)
Messenger Wire: Steel wire for aerial self-supporting applications
Outer Jacket: PVC / PE / LSZH (CPR Dca–B2ca available)
Differences between RG7 CU/48/CCA, RG7 CU/64/CCA and CU/96/CCA
| Feature | RG7 CU/48/CCA | RG7 CU/64/CCA | RG7 CU/96/CCA |
|---|---|---|---|
| Inner Conductor | Solid pure copper (CU) | Solid pure copper (CU) | Solid pure copper (CU) |
| Shield Type | 48 wires, braided CCA | 64 wires, braided CCA | 96 wires, braided CCA |
| Braid Coverage (approx.) | ~70–75% | ~80–85% | 95–98% (nearly full coverage) |
| Shielding Effectiveness (EMI) | Basic | Good | Excellent |
| Mechanical Strength | Moderate | Stronger | Very strong |
| Flexibility | More flexible | Moderate | Slightly stiffer due to dense braid |
| Signal Leakage | Acceptable | Lower leakage | Minimal leakage |
| Attenuation | Higher (weaker shielding) | Lower | Lowest (best signal retention) |
| Weight | Lightest | Moderate | Heaviest |
| Cost | Lowest | Medium | Highest |
Use Case Recommendations
| Application Environment | Recommended Version |
|---|---|
| Short-distance CCTV or indoor wiring | CU/48/CCA |
| Medium-range satellite or CATV installations | CU/64/CCA |
| Long-distance trunk lines, high-interference zones (e.g. near power lines or industrial equipment) | CU/96/CCA |
| High-end broadcast, data centers, or mission-critical networks | CU/96/CCA (best shielding) |
Summary
CU/48/CCA = Economical, flexible, suitable for standard applications.
CU/64/CCA = Balanced performance and cost; suitable for most outdoor or mid-range coax needs.
CU/96/CCA = Premium-grade; used where maximum shielding and signal integrity are critical.
