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.
