Semi-Finished Coaxial Cable – RG8 CU/96/CCA (50Ω)
1. Construction Details
| Component | Specification |
|---|---|
| Inner Conductor： | Solid Pure Copper (CU), Ø ~2.70 mm – highest conductivity, excellent signal integrity |
| Dielectric： | Foamed Polyethylene (PE), Ø ~7.20 mm – low loss, uniform impedance |
| Shield (Braid)： | 96 strands of Copper-Clad Aluminum (CCA) – high coverage (~85–90%) for strong EMI protection |
| Outer Jacket： | Not included – semi-finished (ready for custom extrusion: PVC, PE, LSZH, etc.) |
2. Typical Dimensions
| Component | Approx. Value |
|---|---|
| Inner Conductor Diameter： | ~2.70 mm |
| Dielectric Diameter： | ~7.20 mm |
| Braid Outer Diameter： | ~8.20 mm |
| Final Jacketed OD： | ~10.30–10.50 mm |
3. Performance Parameters (Typical)
| Parameter | Value |
|---|---|
| Impedance: | 50 ± 3 ohms |
| Capacitance: | ~100 pF/m |
| Attenuation @ 100 MHz: | ~5.6–5.8 dB/100 m |
| Shielding Effectiveness: | High (~85–90% coverage) |
| Signal Integrity: | Excellent (CU core) |
| Corrosion Resistance: | Good (CCA coating improves over bare AL) |
| Mechanical Strength: | Medium (CU + CCA construction) |
4. Recommended Applications
High-frequency radio and broadcast signal transmission
Long-distance antenna or base station cabling
Professional-grade OEM production requiring CU core + strong EMI shielding
Telecom and infrastructure RF lines in moderate-to-high EMI environments
