Rubber sheathed 10kV

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.
