Аналог CORDAFLEX (SMK): барабанный кабель (N)TSCGEWÖU 3×150+3×25/3 6/10kV в России — антиторсионная защита, 425 А, замена FeiChun Cable
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.
