Application fit

Is NGFLCGÖU right for your machine?

NGFLCGÖU combines single-plane flat festoon geometry with individual tinned copper braid screens around cores or twisted pairs so VFD power and low-level control signals can share the same crane trolley pack.

Festoon & line chain

Suitable

Primary duty: C-rail, I-beam and wire-rope festoons for VFD crane drives, encoders and bus signals up to 180 m/min.

Energy chain / drag chain

Suitable

Suitable for single-plane carrier chains where bending stays strictly across the flat height H.

Free-hanging vertical run

With conditions

Festoon loops within the 15 N/mm² conductor pull limit; terminate screen braids with 360° EMC clamps at both ends.

Cylindrical / multi-layer drum

With conditions

Single-plane mono-spiral drum winding at ≥ 5 × H radius without lateral fleet angle.

Motorised monospiral reel

Not suitable

Multi-plane motorized crane reeling requires a round screened cable rather than a flat profile.

Use round reeling cable

FAQ

Questions engineers ask first

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

How is the screen constructed inside NGFLCGÖU?

Unlike round EMC cables that use a single overall braid under the outer jacket, NGFLCGÖU applies a tinned copper wire braid directly over each individual core (approx. 60 % optical coverage) or over each twisted pair in bus versions (approx. 80 % coverage), preserving the flexible flat bending profile while optimising transfer impedance at 30 MHz.

How should the individual core screens be earthed at the crane panels?

For variable-frequency drive (VFD) power and high-frequency encoder signals, bond the tinned copper braids across 360° at both the fixed junction box and the moving trolley cabinet using EMC clamping bars. Pigtail earthing adds inductance and degrades high-frequency attenuation above 1 MHz.

What is the difference between single-core screened (C) and pair-screened (2×..)C versions?

Single-core screened versions such as 12×1.5(C) or 4×16(C) place a tinned copper braid around each insulated core for VFD motor leads or individual control circuits. Pair-screened bus versions such as 4×(2×1)C or 7×(2×1)C twist two cores into a balanced pair before braiding, suppressing both crosstalk and common-mode noise on differential signals.

Does the copper braid screen increase the minimum bending radius?

Slightly. Because the tinned copper braid adds radial thickness over the 3GI3 insulation, a screened 4×16(C) cable has a maximum height of 14.4 mm and a minimum moving bend radius of 72 mm, compared with 12.9 mm height and 65 mm radius for unscreened 4×16.

Can NGFLCGÖU and unscreened NGFLGÖU run in the same festoon trolley saddle?

Yes. Both share the same DIN VDE 0250-809 3GI3/5GM3 elastomer compounds, −35 to +80 °C flexing temperature range and 180 m/min trolley speed rating, so screened VFD/signal flat cables and unscreened auxiliary flat cables stack cleanly on the same festoon saddle.
