Application fit

Is (N)TSFLCGEWÖU MV Flat Reeling Cable (3.6/6 & 6/10 kV) right for your machine?

Engineered for high-speed ship-to-shore (STS) container cranes, RMG/RTG yard gantries, bucket-wheel excavators and heavy festoon systems where parallel flat core geometry permits tight single-axis bending radii (408–572 mm) and travel speeds up to 120 m/min without torsional twist.

Festoon & line chain

Suitable

Flat parallel core construction bends cleanly over crane festoon trolleys with a tighter minor-axis bend radius than round MV cables.

Motorised monospiral reel

Suitable

Rated for gantry reeling up to 120 m/min with 15 N/mm² tensile capacity and reversed bending over S-guide rollers (≥ 20 × D).

Vertical / spreader reel

Suitable

Stacks stably on vertically oriented monospiral crane reels where lateral wandering or axial twist is prevented.

Cylindrical / multi-layer drum

Not suitable

Flat profile must not be subjected to torsional stress on cylindrical multi-layer drums; use round (N)TSCGECWÖU for torsion.

Construction

Layer by layer

Three (or four on 6/10 kV 4×35 and 4×70 mm² builds) finely stranded tinned copper conductors insulated with EPR between inner and outer semiconductive field-control layers and individually screened with a concentrically distributed split copper earth conductor (3E or 4E) are arranged side-by-side in a parallel flat plane and vulcanized inside a heavy-duty red polychloroprene (CR / Type 5GM5) outer sheath.

  • Per DIN VDE 0298-3, the effective applied diameter for flat cable bending calculations is D = 1.5 × flat cable height (Max. H), yielding the tabulated minimum bending radius of 15 × Max. H (408–572 mm).
  • On 3.6/6 kV 3×25+3×25/3E, minimum width is corrected to 64.3 mm (datasheet prints 46.3–68.3 mm, a digit transposition of 64.3 mm).

FAQ

Questions engineers ask first

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

When is flat (N)TSFLCGEWÖU preferred over round medium-voltage reeling cables?
In high-speed ship-to-shore (STS) crane festoons and narrow monospiral reels, the parallel flat profile bends around its minor axis (height 24.2–38.1 mm), achieving a significantly smaller bending radius (408–572 mm) and eliminating core corkscrewing at travel speeds up to 120 m/min.
How is the minimum bending radius calculated for a flat MV cable under DIN VDE 0298-3?
DIN VDE 0298-3 defines an equivalent applied diameter D = 1.5 × flat cable height. Multiplying D by 10 for dynamic flexing/reeling gives a minimum bending radius equal to 15 × max cable height (for example, 27.2 mm × 15 = 408 mm on 3.6/6 kV 3×25 mm²).
Why are 4-core configurations (4×35+4×25/4E and 4×70+4×35/4E) offered in the 6/10 kV range?
The 4-core flat constructions allow crane designers to dedicate the fourth screened core position to an auxiliary power circuit, pilot/control bundle or fibre-optic sub-element while maintaining a symmetrical flat cross-section.
Can (N)TSFLCGEWÖU be used in applications with axial torsion?
No. Torsional stress is not permitted on flat medium-voltage cables. Where the cable path involves axial twisting or multi-layer cylindrical drum coiling, specify round (N)TSCGECWÖU or (N)TSCGECECWÖU rated for ±25 °/m torsion.
