Application fit

Is KYFLY right for your machine?

KYFLY (and harmonised H05VVH6-F / H07VVH6-F) is engineered for single-plane bending on indoor and sheltered crane festoon trolleys, hoist loops, and high-bay storage lifts.

Festoon & line chain

Suitable

Primary duty: C-rail and I-beam crane festoon trolleys up to 96 m/min (1.6 m/s) in dry, humid and wet indoor halls.

Energy chain / drag chain

With conditions

Suitable for linear single-plane carrier guides where bending radius ≥ 10 × H and zero axial torsion is maintained.

Free-hanging vertical run

Suitable

Free suspension heights up to 35 m (H07VVH6-F / KYFLY) or 45 m (H05VVH6-F) within the 15 N/mm² static copper tensile limit.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How does KYFLY differ from standard H05VVH6-F and H07VVH6-F flat PVC cables?
Standard H05VVH6-F (300/500 V) and H07VVH6-F (450/750 V) to DIN EN 50214 are rated down to -5 °C or -25 °C in flexing service, whereas KYFLY uses a cold-flexible PVC formulation rated down to -30 °C flexing (-40 °C fixed) and includes multi-core bundled control constructions such as 5×4×0.5 BD and 8×7G0.5.
How is the minimum bending radius determined for KYFLY?
Flat festoon cables bend across their thin dimension (height H) in a single plane. The minimum flexing bending radius is 10 × H (for example, 110 mm for a 4G16 cable with H = 11.0 mm). Never bend a flat cable edgewise across its width W.
Can several KYFLY flat cables be stacked on the same festoon trolley saddle?
Yes. Flat PVC cables are commonly stacked in multi-layer packs on contoured trolley saddles. Place power cables on the outer layer for heat dissipation, apply DIN VDE 0298-4 grouping factors, and size the saddle radius to the thickest cable.
When should I upgrade from KYFLY to KYFLCY or NGFLGÖU?
Specify KYFLCY if the festoon pack runs near variable-frequency drive (VFD) motor leads or carries sensitive encoder/control signals requiring a copper braid EMC screen. Specify NGFLGÖU rubber flat cable for outdoor UV exposure, conductor temperatures up to +90 °C, or travel speeds above 120 m/min.
