Semi-Finished Coaxial Cable – RG6 CCS/48/CCA
1.Structural Specification
| Layer | Material | Specification Details |
|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS) | Ø 1.02 ± 0.02 mm, strong tensile strength with moderate conductivity |
| Bonding Layer | Polymer Film | Micron-level film, improves bonding to dielectric, corrosion control |
| Dielectric | Foamed Polyethylene (FPE) | Ø 4.60 ± 0.10 mm, low εr, ensures 75Ω impedance |
| Shielding | 48 x 0.12 mm CCA braid wires | ~38–42% coverage, moderate EMI resistance |
| Outer Jacket | PVC or PE (black/white) | Ø 6.8 ± 0.10 mm, weather-resistant if PE, flexible if PVC |
2. Electrical Performance (Typical)
| Parameter | Value |
|---|---|
| Characteristic Impedance： | 75 ± 3 ohms |
| Capacitance： | ≤ 67 pF/m |
| Return Loss (5–1000 MHz)： | ≥ 20 dB |
| VSWR (up to 1000 MHz)： | ≤ 1.5:1 |
| Attenuation @ 100 MHz： | ≤ 6.0 dB/100m |
| Attenuation @ 800 MHz： | ≤ 17.5 dB/100m |
3. Mechanical Characteristics
Tensile Strength: Inner conductor resists stretch, suitable for long pulls
Flexibility: Moderate, ideal for internal building wiring
Minimum Bending Radius: 10x outer diameter (approx. 68 mm)
Temperature Range: -20°C to +70°C (PVC), or up to +85°C (PE)
4. Application Scenarios
CCTV camera systems in residential or small office buildings
Short-run CATV installations where high shielding isn’t mandatory
Hotel or apartment MATV networks with centralized splitters
Pre-assembly use in semi-finished cable production or local jacket extrusion
5. Cost-Performance Positioning
| Model Type | Shield Coverage | Cost Level | Recommended Use |
|---|---|---|---|
| CCS/48/CCA | ~40% | ★ | Budget CCTV / light TV signal |
| CCS/64/CCA | ~60% | ★★ | Standard signal shielding |
| CCS/96/CCA | ~85–90% | ★★★ | High-shield environments |
