Semi-Finished Coaxial Cable – RG8 CU/96/AL (50Ω)
1.Construction Details
| Component | Specification |
|---|---|
| Inner Conductor | Solid Pure Copper (CU), ~2.70 mm – excellent electrical performance |
| Dielectric | Foamed Polyethylene (PE), ~7.20 mm – low capacitance, consistent impedance |
| Shielding (Braid) | 96 strands of bare Aluminum (AL) – ~75–80% coverage, high braid density |
| Outer Jacket | Not included – jacket to be extruded separately (PVC, PE, LSZH) |
2. Typical Dimensions (Unjacketed)
| Component | Approximate Value |
|---|---|
| Inner Conductor Diameter | ~2.70 mm |
| Dielectric Diameter | ~7.20 mm |
| Braid Outer Diameter | ~8.20 mm |
| Final Cable OD (jacketed) | ~10.30–10.50 mm |
3. Performance Parameters (Typical)
| Parameter | Value |
|---|---|
| Impedance | 50 ± 3 ohms |
| Capacitance | ~100 pF/m |
| Attenuation @ 100 MHz | ~5.7 dB/100 m |
| Shielding Effectiveness | High (~75–80%) |
| Conductivity | Excellent (pure copper core) |
| Corrosion Resistance | Moderate (bare AL braid) |
| Mechanical Durability | Medium (CU is softer than CCS) |
4. Recommended Applications
High-frequency radio systems (VHF/UHF)
Base station feedlines
Broadcast and telecom signal delivery
OEMs needing low-loss cables with strong shielding
