Current-carrying capacityIf, after all selection criteria have been taken intoaccount, the type of flexible electric cable to beused for cranes and material handling equipment hasbeen decided on, the necessary cross-section of theconductor can be determined either from the currentto be transmitted or from the power.Installation conditions (stretched laying, suspendedfreely in the air, reeled), variations in ambienttemperature, grouping, type of operation (continuousduty, intermittent periodic duty) and the use ofmulti-core cables are to be taken into account. Table4/4 is valid for continuous duty at 30 °C ambienttemperature and three loaded cores, rubber-insulatedor PVC-insulated cables.Ampacity (rubber insulated)CORDAFLEX(SM)PLANOFLEXCORDAFLEX(K)PROTOLON H.V. reeling cables upto 5 kVCross sectionStretchedlayingSuspendedfreelyin airReeled in1 layer 2 layers 3 layers 1) 4 layers 5 layers 6 layers 7 layersAWG/MCM A A A A A A A A AFactor 1 1.05 0.8 0.61 0.49 0.42 0.38 0.27 0.22#18 17 18 14 10 8 7 6 5 4#16 22 23 18 13 11 9 8 6 5#14 29 30 23 18 14 12 11 8 6#12 39 41 31 24 19 16 15 11 9#10 51 54 41 31 25 21 19 14 11#8 70 74 56 43 34 29 27 19 15#6 92 97 74 56 45 39 35 25 20#4 123 129 98 75 60 52 47 33 27#2 165 173 132 101 81 69 63 45 36#1 188 197 150 115 92 79 71 51 41#1/0 221 232 177 135 108 93 84 60 49#2/0 256 269 205 156 125 108 97 69 56#3/0 296 311 237 181 145 124 112 80 65#4/0 342 359 274 209 168 144 130 92 75250 MCM 372 391 298 227 182 156 141 100 82300 MCM 428 449 342 261 210 180 163 116 94350 MCM 471 495 377 287 231 198 179 127 104400 MCM 514 540 411 314 252 216 195 139 113500 MCM 595 625 476 363 292 250 226 161 131600 MCM 672 706 538 410 329 282 255 181 148750 MCM 765 803 612 467 375 321 291 207 1681000 MCM 920 966 736 561 451 386 350 248 2021) The reduction factor is also valid for flat reeling cables (spirally) Table 4/4 part one
