Semi-Finished Coaxial Cable – RG7 CCS/96/AL
1. Cable Structure (No Outer Jacket)
| Layer | Material | Approximate Diameter |
|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS), Ø ~1.13 mm | ~18 AWG |
| Dielectric Insulation | Gas-Injected Foamed Polyethylene (FPE) | ~5.2–5.4 mm |
| First Shield (Foil) | Bonded Aluminum-Polyester Tape (100%) | — |
| Second Shield (Braid) | 96-strand Aluminum (AL), ~60–65% coverage | — |
| Outer Jacket | Not included (semi-finished format) | — |
Outer Diameter (semi-finished core): ~6.0 mm
Finished Cable OD (with jacket): ~7.8–8.2 mm (varies by jacket)
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Characteristic Impedance | 75 ohms |
| Capacitance | ~54 pF/m |
| Velocity of Propagation | ~85% (due to FPE) |
| Attenuation @ 100 MHz | ~6.7–6.9 dB/100m |
| Shielding Effectiveness | High (96-wire AL braid + full foil) |
| Mechanical Durability | High (thanks to CCS conductor) |
3. Key Features
CCS Inner Conductor: Provides strong tensile strength and durability under tension
96-Wire Aluminum Braid: Delivers enhanced EMI shielding over lower braid count versions
100% Foil Coverage: Maintains excellent signal integrity in interference-prone environments
Semi-Finished Format: Ideal for PE, PVC, LSZH, or dual-jacket customization for OEM or export
4. Application Scenarios
Long-distance satellite and broadband distribution
Indoor/outdoor coaxial runs requiring strong shielding but cost-effective materials
Private-label cable production or regional packaging and certification
OEM manufacturing for telecommunications installers and cable assemblers
5. Considerations
Higher attenuation than RG11, due to smaller conductor diameter
Aluminum braid less durable than copper in flexing or mechanical stress
Must be jacketed before use to meet installation and safety standards
