1.Detailed Construction Parameters
| Layer | Material | Specification | Function |
|---|---|---|---|
| Inner Conductor | Solid Bare Copper (CU) | Ø 0.81 mm ± 0.01 mm | Superior conductivity, ensures minimal signal loss |
| Dielectric | Foamed Polyethylene (PE) | Ø ~3.66 mm ± 0.10 mm | Maintains 75Ω impedance; lightweight and low-loss |
| First Shield | Aluminum-Mylar Tape | 100% coverage | Blocks high-frequency interference; primary EMI shield |
| Second Shield (Braid) | 96 x 0.12 mm Aluminum Wires | ~60–80% coverage | High-density braid offers advanced EMI suppression |
| Outer Jacket | Not included | — | Final material to be selected: PVC, PE, FR, or LSZH depending on use case |
2.Electrical Performance Specifications (Typical Values)
| Parameter | Value |
|---|---|
| Characteristic Impedance | 75 ± 3 Ω |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% |
| Attenuation @ 100 MHz | ~5.8 dB/100m |
| Return Loss | ≥ 22 dB (5–1000 MHz) |

3.Recommended Applications
High-resolution CCTV (AHD, HD-TVI, CVI)
Professional video distribution systems
Signal transmission in high-EMI environments (hospitals, transport hubs, factories)
OEM coaxial cable lines requiring top-tier shielding
4.Post-Extrusion Customization
The semi-finished core allows for flexible adaptation in the final manufacturing process:
Outer Jacket Options:
PVC – for flexible indoor applications
PE – for UV- and moisture-resistant outdoor use
FR-PVC / LSZH – to comply with CPR fire classifications (Dca or Eca)
Certifications & Marking:
CE / RoHS / CPR (upon testing and certification)
Sequential meter printing, company branding, production date codes
Packaging:
Bulk reels: 500m or 1000m per drum (wooden/plastic)
Custom spool sizes available for automated extrusion feed
5.Advantages of CU/96/AL Structure
Maximum shielding performance in the RG59 family
Best choice for professional-grade analog video in noisy installations
High conductor purity ensures signal integrity across longer distances
Ideal for premium OEM brands and sensitive applications
