Full technical breakdown Prysmian (Draka) CORDAFLEX SMK series — the "gold standard" for motorized cable reels on portal cranes, stacker-reclaimers, and excavators. Marking (N)TSCGEWÖU, cross-section 3×150+3×25/3, voltage 6/10 kV (max operating 7.2/12 kV). Weight 6.5+ tons/km, OD 58–64 mm, current rating ~425 A (30°C open air), short-circuit ~21.4 kA (1s). Key SMK distinction: built-in anti-torsion guard — reinforced inner sheath with high-strength synthetic braid (aramid/Kevlar) compensating torque from guide rollers and multi-layer winding at speeds up to 120–160 m/min. Without this, standard cables corkscrew and fail on motor drums. Construction: 3×150 mm² tinned copper class 5, split earth 3×(25/3)=3×8.33 mm², EPR insulation type 3GI3, extruded semiconducting screens, polychloroprene (5GM5) or special elastomer outer sheath. Temp -25°C to +80°C standard, Arctic to -40°C. Russian market: GOST КГЭ/КГЭ-ХЛ cables are trailing-only (no anti-torsion) and fail on motor drums. Anhui Feichun offers certified drop-in replacement FC-CORDAFLEX-SMK with integrated aramid anti-torsion braid per VDE, CCV vulcanization, and OD adaptation for existing drums and cable-layers.

Complete engineering guide to MV reeling cables (N)TSCGEWÖU (also searched as NTSCGEWOEU or NTSCGEWOU) with integrated anti-torsion protection: why cables without anti-twist braid fail in 8–14 months (corkscrew effect, delamination, seal loss); how the open synthetic anti-torsion braid between GM1b inner and 5GM5 outer sheaths works; full German type designation decoding per DIN VDE 0250; comparison table of 12 cross-sections from 3×16 to 3×150 mm² at 3.6/6, 6/10, 12/20 kV; selection criteria (reeling speed, drum radius, run length, motor load); typical applications — STS/RTG/MHC port cranes, mining excavators, draglines, ferry berths; pricing analysis Prysmian PROTOLON (SB/SM/SMK) vs Nexans ELASTRON vs Helukabel vs Feichun FC-PLN (50–65% savings); 5-year TCO calculator for port crane.

Configuration 3×95 mm² power + 2×(50/2) mm² split earth + 1×16 mm² control (st). Rated 6/10 kV (max 7.2/12 kV). OD ~56.0–61.5 mm, weight ~5,400–5,650 kg/km, copper index ~3,370 kg/km. Current ~296 A @ 30°C. Bending radius 12–15×OD. Travel speed 120–160 m/min (gantry 240 m/min by agreement). Tensile ~4,275 N dynamic (15 N/mm²; 30 N/mm² acceleration). Temperature -35/+80°C flexing, -50/+80°C fixed.
