Semi-Finished Coaxial Cable – RG11 CCS/96/AL
1. Structure and Dimensions (No Jacket)
| Layer | Material | Approximate Diameter |
|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS), Ø 1.63 mm | 1.63 mm (14 AWG) |
| Dielectric | Gas-injected Foamed Polyethylene (FPE) | ~7.24 mm |
| First Shield | Bonded Aluminum Foil (100% coverage) | — |
| Second Shield (Braid) | 96-strand Aluminum wire (typically 0.16–0.20 mm each) | ~55–65% coverage |
| Outer Jacket | Not present in semi-finished version | — |
Outer Diameter (semi-finished core): ~7.8–8.0 mm
Outer Diameter (when jacketed): ~10.2–10.5 mm
2. Electrical Properties
| Parameter | Typical Value |
|---|---|
| Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (due to foamed dielectric) |
| Attenuation @ 100 MHz | ~5.2–5.4 dB/100m |
| Shielding Effectiveness | Good (due to dense AL braid + foil) |
3. Key Features
Copper-Clad Steel Core: Offers mechanical strength and reduced cost (but higher attenuation than pure copper)
96-wire Aluminum Braid: High shielding performance while maintaining low material cost
Semi-finished Format: Enables custom jacket application (PVC, PE, LSZH, etc.)
Ideal for OEMs: Especially for clients requiring tailored jacket materials or localized compliance
4. Typical Applications
CATV and satellite TV feeder lines
Long-distance signal distribution where cost is a concern
Bulk export cable cores for final jacket processing
Infrastructure projects requiring armored or direct burial versions (after finishing)
5. Considerations
Higher attenuation than CU versions due to CCS conductor
Not suitable for high-power transmission (due to steel core’s higher resistance)
Jacket material and fire/environmental ratings depend on final finishing
