Semi-Finished Coaxial Cable – RG8 CCS/48/AL (50Ω)
1.Construction Details
| Component | Material / Description |
|---|---|
| Inner Conductor | Solid CCS (Copper-Clad Steel), ~2.70 mm – high tensile strength, low cost |
| Dielectric | Foamed Polyethylene (PE), ~7.20 mm – stable impedance and low capacitance |
| Shield (Braid) | 48 strands of bare Aluminum (AL) – light shielding, ~50–60% coverage |
| Jacket | Not included – semi-finished, for OEM jacketing with PVC, PE, LSZH, etc. |
2. Typical Dimensions (Bare Cable)
| Component | Approx. Size |
|---|---|
| Inner Conductor Diameter | ~2.70 mm |
| Dielectric Diameter | ~7.20 mm |
| Braid Diameter | ~8.00 mm |
| Final OD (with jacket) | ~10.30–10.50 mm (after extrusion) |
3. Performance Characteristics (Typical):
