Semi-Finished Coaxial Cable RG59 CCS/64/AL
Standard Type: RG59 75Ω
Construction Stage: Semi-finished (no outer jacket)
1.Structural Composition
| Layer | Material | Specification | Function |
|---|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS) | Ø 0.81 mm ± 0.01 mm | Combines mechanical strength of steel with conductivity of copper; cost-effective for analog video |
| Dielectric | Foamed Polyethylene (PE) | Ø 3.66 mm ± 0.10 mm | Low dielectric constant for reduced signal loss; maintains 75Ω impedance |
| First Shield | Aluminum-Mylar Tape | ≥ 100% coverage | Electrostatic shielding and isolation from external interference |
| Second Shield (Braid) | Aluminum Wire | 64 strands of Ø 0.12 mm | Additional EMI shielding; braid coverage approx. 40%–60% |
| Outer Jacket | Not Included | —— | To be applied based on final application (PVC for indoor, PE for outdoor) |
2.Technical Characteristics
| Parameter | Typical Value |
|---|---|
| Impedance | 75 ± 3 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% |
| Attenuation @ 100 MHz | ~7.5 dB/100m |
| Shielding Effectiveness | ≥ 40 dB |
| Return Loss | ≥ 20 dB (5–1000 MHz) |
