Cold bending PUR cable

12 Min Read
Full technical breakdown Prysmian Draka BUFLEX XTREME 3×70+3×35/3 0.6/1 kV: specialized low-voltage reeling cable for mining excavators, drill rigs, draglines, and conveyors in open-pit and underground mining. Construction: 3 power cores 70 mm² (class 5 flexible copper) + 3 earth cores 35 mm² + 3 pilot/control cores, XLPE insulation 90°C, PUR outer sheath (oil/abrasion resistant, Shore A ~85–92), aramid (Kevlar) strength member for extreme mechanical stress: torsion ±360°/m, tension up to 5,000 N, abrasion >50,000 cycles. Operating temperature -35°C to +90°C standard, -40°C extended. Reeling speed up to 150 m/min. Minimum bending radius 6× OD. VDE 0250-812 certified. Russian GOST equivalent: КГЭ-Ш 0.6/1 kV (Flexible Shielded Mining Cable) per GOST 31945-2012 with additional aramid element and PUR sheath. Applications: open-pit (Kuzbass coal, Kursk Magnetic Anomaly iron ore, Ural copper), underground (Vorkuta coal, Perm potash). Cost: original BUFLEX XTREME €1,800–2,400/km vs Feichun FC-BUFLEX-XT €650–850/km (55–65% savings). Long-term import substitution strategy for Russian mining industry.
