Semi-Finished Coaxial Cable RG59 CCS/48/AL
Type: 75 Ohm Coaxial Cable Core (Without Outer Jacket)
Manufacturing Stage: Semi-finished core for further extrusion or assembly
1.Structural Configuration
| Layer | Material | Specification | Function |
|---|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS) | Ø 0.81 mm ± 0.01 mm | Provides tensile strength and cost-efficient signal conduction |
| Insulation (Dielectric) | Physical Foamed PE | Ø ~3.66 mm ± 0.10 mm | Maintains impedance stability, reduces capacitance |
| First Shield | Bonded or unbonded Aluminum Foil | 100% coverage | Blocks high-frequency EMI and improves signal integrity |
| Second Shield (Braid) | 48-strand Aluminum Wire (Ø 0.12 mm) | Braid coverage: ~35%–45% | Low-cost shielding layer; lighter and more flexible than copper braid |
| Outer Jacket | Not included (semi-finished) | — | To be customized based on final application: PVC, PE, dual-jacket, etc. |
2.Electrical Performance (Typical Values)
| Parameter | Value |
|---|---|
| Impedance | 75 ± 3 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% |
| Attenuation @ 100 MHz | ~8.2 dB/100m |
| Shielding Effectiveness | ≥ 35 dB |
| Return Loss (5–1000 MHz) | ≥ 18–20 dB |
