Semi-Finished Coaxial Cable –RG11 CU/64/AL
1. Cable Structure (No Jacket)
| Layer | Material | Approx. Diameter |
|---|---|---|
| Inner Conductor | Solid Copper (CU), Ø 1.63 mm | 14 AWG |
| Dielectric Insulation | Gas-injected Foamed Polyethylene (FPE) | ~7.24 mm |
| Shield 1 (Tape) | Bonded Aluminum-Polyester Foil (100%) | — |
| Shield 2 (Braid) | 64-strand Aluminum (AL), ~40% coverage | — |
| Outer Jacket | Not included (semi-finished version) | — |
Outer Diameter (core only): ~7.8 mm
Final Jacketed Diameter: ~10.2–10.5 mm (depending on jacket type)
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Characteristic Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (due to FPE insulation) |
| Attenuation @ 100 MHz | ~5.2–5.4 dB/100m |
| Shielding Effectiveness | Moderate to Good |
| Inner Conductor Resistance | Very Low (due to solid copper) |
3. Key Features
Solid Copper Conductor: Offers excellent signal quality with low attenuation across long runs
64-Wire AL Braid: Provides better EMI shielding than 48-braid versions while keeping cost lower than copper-based braids
100% Foil Coverage: Reduces interference and ensures stable signal integrity
Jacket-Free Core: Allows manufacturers to add PVC, PE, LSZH, UV-resistant, or dual jackets based on use case
4. Common Applications
CATV trunk lines and satellite feeder cables
Long-distance broadband signal delivery
Export markets requiring custom jacket finishing
OEM production of finished RG11 cables for various environmental or compliance demands
5. Considerations
Aluminum braid is less mechanically durable than CCA or copper
Not suited for high-RF-noise industrial settings without additional shielding
Outer jacket must be applied before installation
