Application & Operating Conditions
KYFLTFCY is a 300/500 V copper-shielded flat PVC power and control cable with integrated steel suspension elements (TF = Tragorgan Flachleitung), purpose-built for overhead cranes, container-handling hoists, high-bay stacker cranes, and deep vertical suspended drops requiring both single-plane bending and tensile strain relief.
Long-Drop Hoists & High-Bay Stackers
Dual outer galvanized steel suspension ropes carry the vertical suspended dead weight of long hanging loops so tensile strain never transfers onto the Class 5 copper conductors.
VFD-Driven Crane Festoon Systems
Braided copper EMC shielding around the internal core groups blocks high-dV/dt inverter noise from corrupting hoist encoder, limit-switch, and safety PLC circuits.
Compact Single-Plane Loop Stacking
Flat ribbon geometry bends cleanly in one plane to a tighter minimum radius than equivalent multi-core round cables, minimizing festoon parking-station length on indoor/covered beams.
Suspension Termination Requirement: Always anchor both outer steel support elements into mechanical strain-relief clamps at the fixed beam and moving trolley/hoist boxes before landing copper cores on terminal blocks—never allow copper conductors or EMC braids to bear tensile suspension load.
Cable Construction (KYFLTFCY Self-Supporting EMC Flat Design)
Built around a parallel flat web layout that isolates the two outer mechanical load-bearing steel wire ropes from the central copper-shielded electrical sub-bundles.

Frequently Asked Questions (FAQ)
Key technical questions when selecting KYFLTFCY steel-supported screened flat festoon cables.
How does KYFLTFCY differ from standard KYFLCY flat festoon cable?
Both KYFLTFCY and KYFLCY incorporate copper EMC shielding inside a flexible flat PVC jacket; however, KYFLTFCY adds integrated galvanized steel suspension elements (“TF”) along the outer edges of the flat web. Choose KYFLTFCY whenever long vertical drop loops or suspended hoist travel would otherwise place excessive tensile stress on the copper conductors.
Can KYFLTFCY be wound around two axes or twisted torsionally?
No. Like all flat ribbon crane cables, KYFLTFCY is engineered strictly for strong operational bends in a single plane perpendicular to its wide face. For torsional twisting or multi-plane basket coiling, specify a round aramid- or sisal-supported crane cable.
Is KYFLTFCY suitable for sub-zero outdoor port cranes?
KYFLTFCY is rated down to -25°C in mobile operation and -40°C fixed in dry, damp, and wet halls. For permanent uncovered coastal port cranes exposed to intense solar UV, salt spray, and +90°C conductor loading, specify our screened flat rubber (N)GFLCGÖU series.
What standard drum lengths and custom core combinations can TEBAOFLEX supply?
Standard export packing is 500 m on fumigated wooden drums, with custom cut lengths, 5-/20-/28-core control layouts, and project-rated steel rope diameters manufactured on short lead times.
