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.

Full technical breakdown Draka/Prysmian BUFLEX M (N)TSCGEWÖU 3×185+3×35/3 6/10 kV: super-heavy flexible medium-voltage cable for main power supply of giant bucket wheel excavators, stacker-reclaimers, STS container cranes, and floating docks. Weight 8+ tons/km, OD 67–73 mm, current rating ~490 A (30°C open air), voltage 6/10 kV (max operating 7.2/12 kV). Construction: 3 power cores 185 mm² tinned copper class 5 + split earth 3×(35/3)=3×11.67 mm² + 3 pilot cores, special EPR insulation type 3GI3, extruded semiconducting screens inner/outer for electric field leveling at 6/10 kV, wear-resistant PUR/rubber outer sheath 5GM5. Short-circuit current (1s) ~26.5 kA. Min bending radius 12–15× OD (dynamic super-diameter drums). Temp range -25°C to +80°C standard, special versions to -40°C. Manufacturing challenge: 70+ mm diameter and 8+ tons/km require inclined CCV tower lines preventing sag/deformation of heavy cores before insulation cure. Anhui Feichun — proven manufacturer offering full drop-in replacement with identical construction, concentricity guarantee, and sheath adaptation for existing cable-layers and motor reels.
