Semi-Finished Coaxial Cable —RG7 CU/96/AL
1.Cable Structure (No Outer Jacket)
| Component | Description |
|---|---|
| Inner Conductor | Solid bare copper (CU), diameter ≈ 1.13–1.20 mm |
| Dielectric | Gas-injected or solid foamed polyethylene (FPE), diameter ≈ 5.0–5.3 mm |
| First Shield | Aluminum-polyester foil bonded to dielectric (100% coverage) |
| Second Shield | 96-wire aluminum braid, ~95–98% optical coverage |
| Outer Jacket | Not included – core supplied for final jacketing |
2. Electrical & Performance Characteristics
| Parameter | Typical Value (@100 MHz) |
|---|---|
| Impedance | 75 ± 3 ohms |
| Capacitance | 53 – 55 pF/m |
| Velocity of Propagation | ≥ 83% |
| Attenuation @100 MHz | ≤ 7.8 dB/100m |
| Return Loss @100 MHz | ≥ 20 dB |
| Shielding Effectiveness | ≥ 45 – 50 dB |
| DC Resistance (inner conductor) | ≤ 21 ohm/km |
Final attenuation depends on dielectric quality and extrusion tightness of the braid.
3.Key Advantages
1. Solid Copper Conductor for Superior Signal Quality
Ensures low transmission loss, high conductivity, and long-distance performance
Suitable for HD CCTV, satellite uplinks, and RF headends
2. 96-Wire Aluminum Braid – Excellent Coverage, Lower Weight
Up to 98% optical coverage = strong EMI rejection
Lighter and more cost-effective than copper or CCA braiding
Ideal for cost-conscious large projects where high shielding is still required
3. OEM-Ready for Custom Jacketing
Designed for downstream sheathing with:
PVC (indoor use)
PE (outdoor/UV-resistant)
LSZH (fire-rated CPR Dca/Cca)
4. Lightweight & Material Efficient
Aluminum braid reduces weight and overall material cost, while maintaining strong shielding performance
4.Packaging & Supply Format
| Item | Specification |
|---|---|
