FAQ

Questions engineers ask first

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

When are single-core Festoonflex C-PUR-HF cables (1×25 to 1×300 mm²) used on cranes?

High-power ship-to-shore (STS) and RMG container cranes require phase currents from 138 A up to 649 A where a 4-core cable would be too thick and stiff for the festoon trolley saddle. Running single-core D12YC11Y-O phase leads with individual 85 % tinned copper braid screens keeps bending radius down to 6 × D while maintaining full VFD EMC containment.

What is the difference between overall-screened pairs (4×(2×1.5)) and individually screened pairs (3×(2×1.5)C)?

Overall-screened pair constructions (D12YC11Y-O) place a single tinned copper braid around the entire twisted-pair bundle under the outer PUR sheath, whereas individually screened pair constructions (D12Y11Y-O ..×(2×..)C) wrap a dedicated tinned copper screen around each twisted pair to prevent pair-to-pair crosstalk between encoder, resolver and analogue channels.

Does Festoonflex C-PUR-HF use bare or tinned copper conductors?

Across DIN VDE 0250-1 factory specifications for individually screened twisted-pair festoon cables, 12×(2×0.5)C spans 16.5 mm minimum to 21.0 mm maximum outer diameter depending on central filler geometry and pair screen lay.

Can Festoonflex C-PUR-HF operate permanently underwater?

Yes. The crosslinked/thermoplastic polyurethane (PUR-HF) outer jacket is hydrolysis- and microbe-resistant and is rated for permanent immersion in non-drinking water up to 50 m depth as well as outdoor UV exposure.
