FAQ

Questions engineers ask first

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

What does the designation (N)TSCGEWÖU stand for under DIN VDE 0250-813?

(N) indicates construction based on German national standard DIN VDE 0250-813; T denotes a reeling/trailing drum cable; S stands for heavy-duty mining/crane service; C and GE indicate extruded semi-conductive elastomeric field-control layers with EPR (3GI3) core insulation; WÖU designates a weather-, oil- and flame-resistant heavy-duty double elastomeric sheath system (5GM3 inner, 5GM5 outer) with an embedded anti-torsion braid.

How does NTSCGEWÖU control the medium-voltage electric field without a metallic copper braid screen?

Each phase core has a triple-extruded dielectric package: an inner semi-conductive EPR layer over the Class 5 conductor, high-grade 3GI3 EPR insulation, and a cold-strippable outer semi-conductive NBR/EPR layer (resistivity ≤ 200 Ω·m). The three phase cores are laid up symmetrically with the protective earth conductor split into three interstitial parts in continuous contact with the outer semi-conductive core screens. If your protection scheme requires an individual metallic copper wire/tape screen per phase, select (N)TSCGECEWÖU instead.

What minimum drum diameter and S-bend spacing are required for medium-voltage reeling?

Per DIN VDE 0298-3 and manufacturer reeling data, the minimum bending radius is 6 × OD for fixed routing, 10 × OD for free-moving loops, 12 × OD for forced reeling on monospiral or cylindrical drums, and 15 × OD over deflection sheaves. Where the cable passes through S-type directional changes into different planes, maintain at least 20 × OD between opposing pulley centres to prevent premature core migration.

How is the maximum permissible pulling force calculated for a given cross-section?

Continuous tensile load is rated at 20 N/mm² of total phase-conductor copper cross-section (excluding the three split earth conductors), and up to 25–30 N/mm² during dynamic crane acceleration. For example, a 3 × 50 + 3 × 25/3 mm² cable has 150 mm² of phase copper, giving a permanent pulling rating of 3,000 N and a dynamic acceleration peak of 3,750 to 4,500 N.

Can NTSCGEWÖU be supplied with integrated optical fibres for crane automation and bus telemetry?

Yes. For ship-to-shore cranes, automated stacking cranes and stacker-reclaimers that combine medium-voltage power with real-time PLC or camera data, the cable is manufactured as (N)TSKCGEWÖU (or LWL variant), replacing one interstitial earth position or adding a buffered fibre-optic module (6 to 24 single-mode or multimode fibres) while preserving the same 5GM3/5GM5 reinforced sheath.
