Full technical breakdown Prysmian (Draka) CORDAFLEX SME — Arctic modification of (N)TSCGEWÖU 6/10 kV motorized drum cable, designed for reeling at extreme cold to -40°C. Standard rubber/PUR at such temperatures becomes brittle as glass and cracks on first guide roller bend. SME solves this with three engineering innovations: (1) cold-resistant polychloroprene outer sheath "5GM5 Arctic blend" with non-freezing plasticizers maintaining elasticity at -40°C; (2) reinforced tensile strength 20 N/mm² (vs standard 15), compensating lubricant thickening in drum gearboxes and jerks during winter starts; (3) micro-filtered EPR compound 3GI3 maintaining dielectric properties at -40°C without cracking. Temp range -40°C to +80°C (flexing), -50°C to +80°C (fixed). Winding speed up to 120 m/min. VDE 0250-813 (SME modification). Two import substitution paths: (1) FeiChun NTSCGEWÖU-Cold — certified equivalent with Arctic additives for Siberia/Canada; (2) КГЭ-ХЛ 6 kV — Russian GOST to -60°C, but mechanically weaker than SME and lower winding speeds.

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.
