Semi-Finished Coaxial Cable – RG6 CU/48/AL
1.Structural Specification
| Layer | Material | Specification & Function |
|---|---|---|
| Inner Conductor： | Pure Copper (CU) | Ø 1.02 ± 0.02 mm – Excellent electrical conductivity and durability |
| Bonding Layer： | Polymer Film (optional) | Improves adhesion to dielectric, reduces oxidation |
| Dielectric： | Foamed Polyethylene (FPE) | Ø 4.60 ± 0.10 mm – Maintains 75Ω impedance and low signal loss |
| Shielding (Braid)： | 48 x 0.12 mm Aluminum wires | ~38–42% coverage – Basic EMI protection with lightweight design |
| Outer Jacket： | PVC or PE (black or white) | Ø 6.8 ± 0.10 mm – Flexible and UV-resistant for indoor/outdoor use |
2. Electrical Performance (Typical)
| Parameter | Value |
|---|---|
| Characteristic Impedance： | 75 ± 3 ohms |
| Capacitance： | ≤ 67 pF/m |
| Return Loss (5–1000 MHz)： | ≥ 20 dB |
| Attenuation @ 100 MHz： | ≤ 5.5 dB/100m |
| Attenuation @ 800 MHz： | ≤ 15.5 dB/100m |
3. Mechanical Properties
Signal Quality: Strong due to solid copper conductor
Shielding Performance: Basic, suitable for low-noise environments
Weight: Lower than copper braid types, easier handling and installation
Temperature Range: -20°C to +70°C (PVC), up to +85°C (PE)
Bending Radius: ≥ 10× OD (~68 mm)
4. Recommended Applications
Analog and digital TV signal distribution (MATV/CATV)
Short-to-medium range CCTV installations
Low-interference environments where copper braid is not required
Cost-sensitive residential cable rollouts
5. Comparative Positioning
| Model Type | Inner Conductor | Shielding Type | Shield Coverage | Signal Stability | Target Use Cases |
|---|---|---|---|---|---|
| CU/48/AL | Copper | 48 AL braid | ~40% | Medium | TV/CCTV in low EMI areas |
| CU/64/AL | Copper | 64 AL braid | ~60% | Good | Standard TV/CCTV installs |
| CU/96/AL | Copper | 96 AL braid | ~85–90% | Excellent | HD CCTV / long RF runs |
