Semi-Finished Coaxial Cable – RG6 CCS/64/AL
1.Structural Composition
| Layer | Material | Specification & Function |
|---|---|---|
| Inner Conductor： | Copper-Clad Steel (CCS) | Ø 1.02 ± 0.02 mm – Combines conductivity with strong tensile strength |
| Bonded Layer： | Polymer Bond (optional) | Improves adhesion between dielectric and conductor |
| Dielectric： | Foamed Polyethylene (FPE) | Ø 4.60 ± 0.10 mm – Maintains 75Ω impedance, low loss |
| Shielding (Braid)： | 64 x 0.12 mm Aluminum wires | ~55–60% coverage – Medium EMI protection for standard applications |
| Outer Jacket： | PVC or PE (black/white) | Ø 6.8 ± 0.10 mm – Weather-resistant and flexible |
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： | ≤ 5.7 dB/100m |
| Attenuation @ 800 MHz： | ≤ 16.0 dB/100m |
3. Mechanical Features
Shielding Level: Mid-range for CATV and CCTV use
Cable Weight: Lighter than CCA or CU shielded types
