Semi-Finished Coaxial Cable – RG11 CU/48/CCA
1. Construction Details (No Outer Jacket)
| Layer | Material | Approximate Diameter |
|---|---|---|
| Inner Conductor | Solid Copper (CU) – Ø 1.63 mm (14 AWG) | 1.63 mm |
| Dielectric | Physically Foamed Polyethylene (FPE) | ~7.24 mm |
| First Shield (Foil) | Bonded Aluminum-Polyester Tape (100%) | — |
| Second Shield (Braid) | 48 wires of CCA (typically 0.16–0.20 mm) | ~30–35% coverage |
| Outer Jacket | Not present – intended for customization | — |
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (due to FPE dielectric) |
| Attenuation @ 100 MHz | ~5.4 dB/100m (depending on braid %) |
| Shielding Effectiveness | Medium (due to 48-wire CCA braid) |
3. Key Benefits
Solid Copper Core: Ensures low signal loss across long cable runs.
48-wire CCA Braid: More economical than 64/96 braid options, suited for non-critical EMI environments.
Semi-Finished Format:
Enables custom jacket application (e.g. PE, PVC, LSZH, UV-resistant).
Facilitates regional compliance or branding for export.
Supports flexibility in assembly (armoring, bundling, etc.).
4. Common Use Cases
Manufacturing of final RG11 coaxial cables for:
CATV infrastructure
Satellite TV systems
Broadband distribution networks
OEM or export-grade customized cables
Projects requiring:
Custom jackets (e.g., for UV, water, or fire protection)
Armored sheathing or burial-ready design
5. Comparison with Other RG11 Semi-Finished Types
| Specification | CU/48/CCA | CU/64/CCA | CU/96/CCA |
|---|---|---|---|
| Braid Density | ~30–35% | ~40–45% | ~60–65% |
| EMI Shielding | Moderate | Good | Excellent |
| Cost Efficiency | High | Balanced | Moderate |
| Signal Performance | Good | Better | Best (among CCA) |
