CABLES AND WIRES - Novkabel

EpN 78 NTSCGEWöu ... /3Flexible medium voltage mining cableStandard: SRPS N.C5.374Nominal voltage U 0 /U: 3,6/6 kV 6/10 kV 12/20 kV 18/30 kVTest voltage: 11 kV 17 kV 29 kV 43 kVCONSTRUCTIONConductor: tinned copper conductor class 5.Semi conductive layer: rubber compound/tape.Insulation: based on EPR rubber.Protective conductor: tinned copper conductor class 5 withsemi conductive layer.Core cable: 3 power cores and 3 protective cores placed in thespace between power cores.Inner sheath: based on natural/synthetic rubber.Sheath: based on polychloroprene rubber, oil and abrasionresistant, flame retardant.Sheath colour red.APPLICATIONCables are intended for operating in extremely heavy conditions onsurface pit mines, shipyards, quarries and industry. They aresuitable for supply of heavy excavators, cranes truck transportersloading bridges and other machines. They are very flexible andpossible for continuous movement.CONSTRUCTION DATAnxq + n 1xq 1 Cu number3,6/6 kV 6/10 kV 12/20 kVDiameter Mass Diameter Mass Diameter Mass[mm 2 ] [kg/km] [mm] [kg/km] [mm] [kg/km] [mm] [kg/km]3x16 + 3x6 634 42 2196 44 2341 – –3x16 + 3x10 749 42 2303 – – – –3x25 + 3x10 1008 44 2679 46 2825 – –3x25 + 3x16 1181 44 2815 – – – –3x35 + 3x10 1296 47 3212 49 3365 – –3x35 + 3x16 1469 47 3347 49 3506 – –3x50 + 3x16 1901 52 4024 55 4414 64 60813x50 + 3x25 2160 52 4220 – – – –3x70 + 3x16 2477 57 5151 – – 72 70263x70 + 3x25 2736 57 5347 – – – –3x95 + 3x16 3197 61 6100 63 6309 – –3x95 + 3x25 3456 61 6295 – – – –3x120 + 3x16 3917 66 7189 – – – –3x120 + 3x25 4176 66 7349 – – – –3x120 + 3x35 4464 66 7685 68 7614 – –3x150 + 3x25 5040 71 8773 – – – –3x150 + 3x35 5328 71 8973 – – – –3x185 + 3x25 6048 73 10193 75 10370 – –3x185 + 3x35 6336 73 10393 – – – –3x185 + 3x50 6768 73 10702 – – – –087n – number of the power cores; q – nominal cross section power conductorn 1 – number of the protective cores; q 1 – nominal cross section protective conductorPermissible conductor temperature:operating temperature, max +90°C; in short circuit (max 5 s), max +250°C.Permissible environment temperature:mobile from -25°C to +40°C; fixed laying from -30°C to +40°C.Smallest bending radius: 12D (D - cable diameter).
