Semi-Finished Coaxial Cable – RG8 CU/48/CCA (50Ω)
1. Construction Details
| Component | Specification |
|---|---|
| Inner Conductor： | Solid Pure Copper (CU), ~2.70 mm – maximum electrical conductivity |
| Dielectric： | Foamed Polyethylene (PE), ~7.20 mm – ensures low capacitance and impedance stability |
| Shielding (Braid)： | 48 strands of Copper-Clad Aluminum (CCA) – ~55–60% coverage |
| Outer Jacket： | Not included – for custom extrusion (PVC, PE, or LSZH) |
2. Typical Dimensions (Unjacketed)
| Component | Value |
|---|---|
| Inner Conductor Diameter： | ~2.70 mm |
| Dielectric Diameter： | ~7.20 mm |
| Braid Outer Diameter： | ~8.00 mm |
| Final OD (with jacket)： | ~10.30–10.50 mm |
3. Performance Parameters (Typical)
| Parameter | Value |
|---|---|
| Characteristic Impedance： | 50 ± 3 ohms |
| Capacitance： | ~100 pF/m |
| Attenuation @ 100 MHz： | ~5.9 dB/100 m |
| Shielding Effectiveness： | Moderate (~55–60%) |
| Conductivity： | Excellent (copper core) |
| Shield Durability： | Medium (CCA braid) |
| Cost-Performance Balance： | High |
4. Recommended Applications
Indoor RF signal distribution
Medium-range antenna cables
OEM projects requiring pure copper center + basic shielding
Installations prioritizing signal strength over shielding level
