Application fit

Is NGFLGÖU right for your machine?

Flat cables bend cleanly in one plane around their thin axis (height H), allowing tighter loop radii and stacked multi-cable saddles on festoon trolleys — but they cannot absorb torsion or multi-plane deflection.

Festoon & line chain

Suitable

Primary duty: C-rail, I-beam and wire-rope festoon trolleys up to 180 m/min (up to 250 m/min on straight tracks).

Energy chain / drag chain

Suitable

Suitable for single-plane carrier chains and handling gantries where cores bend only across the flat height.

Free-hanging vertical run

With conditions

Festoon loops and hoist drops within the 15 N/mm² conductor tensile limit; avoid twist along the suspended loop.

Cylindrical / multi-layer drum

With conditions

Single-plane winding on mono-spiral drums at ≥ 5 × H bending radius without lateral deflection.

Motorised monospiral reel

Not suitable

Long-travel motorized gantry reeling with guide rollers and side fleet requires a round reeling cable.

FAQ

Questions engineers ask first

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

Why does NGFLGÖU use Class 6 stranding up to 25 mm² and Class 5 from 35 mm²?

DIN VDE 0250-809 specifies extra-fine IEC 60228 Class 6 bare copper strands for cross-sections up to 25 mm² because control and medium-power festoon loops fold around tight trolley saddles (18–78 mm radius). From 35 mm² upwards, Class 5 fine stranding provides the mechanical stability needed for heavy parallel power cores.

How is the minimum bending radius calculated for a flat festoon cable?

For flat cables, the bending radius is measured against the flat cable height (thickness H), not the width (W), because the cable bends in one plane only. Under DIN VDE 0298-3, free-moving festoon loops require approximately 3 × to 5 × H depending on cable thickness — check the exact value in the size table.

When should I choose screened NGFLCGÖU instead of unscreened NGFLGÖU?

Choose NGFLGÖU for standard AC power, contactor control and limit-switch circuits. If the festoon carries variable-frequency drive (VFD) motor leads, encoder feedback, analogue sensors or fieldbus pairs in the same saddle pack, specify NGFLCGÖU with tinned copper braided screens on individual cores or pairs.

Can several NGFLGÖU flat cables be stacked on the same festoon trolley saddle?

Yes. Stacking flat cables on a contoured saddle is standard crane practice. Place power cables on the outer or lower layer for heat dissipation, apply DIN VDE 0298-4 grouping reduction factors to the current rating, and size the saddle radius to the thickest cable in the pack.

What is the difference between NGFLGÖU and PVC flat cables such as H07VVH6-F?

NGFLGÖU uses 3GI3 EPR core insulation and a 5GM3 polychloroprene rubber outer sheath instead of PVC. That allows a +90 °C conductor temperature, outdoor UV/ozone/oil exposure and flexing down to −35 °C, whereas PVC flat cables stiffen in cold weather and are mainly suited to indoor cranes.
