Special Purpose, Flat, and Coaxial Cables Selection Guide
Selection criteria for H07VVH6-F flat festoon/elevator cables and RG6/RG59 coaxial cables by bending radius, conductor class, and impedance.
Applications involving continuous linear motion on crane festoon tracks, elevator hoistways, or high-frequency RF/video transmission require specialized constructions found in Other Cables. Key selection parameters include minimum bending radius, flex life, and characteristic impedance.
Flat festoon cables and coaxial transmission lines
- Flat crane and elevator cables (H07VVH6-F): Parallel core arrangement prevents axial twisting and allows tight bending radii on overhead crane festoon trolleys and hoist systems.
- Coaxial cables (RG6 / RG59 / RG11): Maintain a 75 Ω characteristic impedance with foil + braid shielding for low-attenuation satellite/SMATV distribution and CCTV video links.
Special cable comparison table

| Coaxial cable (RG6 / RG59) | 75 Ohm coaxial | Foil + braid shield, low high-frequency attenuation | SMATV satellite distribution and CCTV video lines | Coaxial Cables |
Frequently asked questions
Why are flat cables preferred over round flexible cables on overhead cranes?
On crane festoon tracks, cables repeatedly fold and unfold along a single plane; parallel cores in a flat cable eliminate internal corkscrewing and allow a much tighter bending radius than round cables.
What is the difference between RG6 and RG59 coaxial cable?
RG6 has a larger center conductor (typically 1.02 mm / 18 AWG) and lower signal attenuation at high frequencies for long satellite/RF runs, while RG59 is thinner and more flexible for shorter CCTV camera runs.
