Semi-Finished Coaxial Cable – RG8 CU/64/CCA (50Ω)
1.Construction Details
| Component | Specification |
|---|---|
| Inner Conductor： | Solid Pure Copper (CU), Ø ~2.70 mm – premium conductivity for signal clarity |
| Dielectric： | Foamed Polyethylene (PE), Ø ~7.20 mm – low loss, consistent impedance |
| Shield (Braid)： | 64 strands of Copper-Clad Aluminum (CCA) – ~65–70% coverage, moderate shielding |
| Outer Jacket： | Not included – semi-finished, ready for extrusion (PVC/PE/LSZH) |
2. Typical Dimensions
| Component | Approx. Value |
|---|---|
| Inner Conductor Diameter： | ~2.70 mm |
| Dielectric Diameter： | ~7.20 mm |
| Braid Outer Diameter： | ~8.10 mm |
| Jacketed Outer Diameter： | ~10.30–10.50 mm |
3. Performance Specifications (Typical)
| Parameter | Value |
|---|---|
| Impedance： | 50 ± 3 ohms |
| Capacitance： | ~100 pF/m |
| Attenuation @ 100 MHz： | ~5.8 dB/100 m |
| Shielding Effectiveness： | Moderate (~65–70%) |
| Conductor Quality： | Excellent (solid CU) |
| Tensile Strength： | Moderate (CU core + CCA braid) |
| Corrosion Resistance： | Good (CCA better than AL) |
4. Recommended Applications:
Mid-range RF and telecommunications systems
Antenna feed lines with moderate EMI exposure
OEM cable production requiring high signal performance
Projects balancing performance vs. cost
