ConductorsConductors for flexible electric cables are designedaccording to DIN VDE 0295. Nowadays, theconductors are made of copper (Cu). Aluminium andother materials have not found general acceptance.An overview of the common kinds of conductors isshown in table 4/19. In many countries, the designof the conductors according to DIN VDE 0295 isaccepted. The regulation corresponds to CENELEC HD383.S2 and IEC 228. The conductor classes F, FS andFF are employed for flexible electric cab es for cranesand materia handling equipment. The conductorclasses are divided into nominal cross-sections. Theindividual conductor classes F, FS and FF and thenominal cross-sections are defined by specificationof the maximum diameter of the single wires andby the maximum resistance of the conductor at 20°C (see also table 4/20).These flexible conductorsare made of bare or tinned annealed copper. Theconductors are constructed of many single wires, allof which must have the same diameter.Common types of conductorsAbbreviation Designation Specification/ regulationRE conductor Circular, solid DIN VDE 0295 Class1RM conductorRMV conductorCircular, strandedCircular, stranded,compactedDIN VDE 0295 Class2DIN VDE 0295 Class2F conductor Finely stranded DIN VDE 0295 Class5FS conductorFF conductorTable 4/19Very finelystrandedExtremly finelystrandedDIN VDE 0295 Class6Flexible conductorsPrysmian specificationNominalcrosssectionmm 2Nominalcrosssection*(AWG)Max. diameter of the single wires mm Resistance of the conductor at 20 °C/ 68°F,F conductor(class 5)FS conductor(Prysmian)FF conductor(class 6)Bare singlewiresΩ /kmΩ / feetTinnedsingle wiresΩ /kmΩ / feet1.5 #16 0.26 0.21 0.16 13.3 4.043 13.7 4.1642.5 #14 0.26 0.21 0.16 7.98 2.426 8.21 2.4954 #12 0.31 0.26 0.165 4.95 1.505 5.09 1.5476 #10 0.31 0.26 0.21 3.30 1.003 3.39 1.03010 #8 0.41 0.26 0.21 1.91 0.581 1.95 0.59316 #6 0.41 0.31 0.21 1.21 0.368 1.24 0.37725 #4 0.41 0.31 0.21 0.780 0.237 0.795 0.24235 #2 0.41 0.31 0.21 0.554 0.168 0.565 0.17250 #1/0 0.41 0.36 0.31 0.986 0.300 0.393 0.11970 #2/0 0.51 0.36 0.31 0.272 0.083 0.277 0.08495 #4/0 0.51 0.41 0.31 0.206 0.063 0.210 0.064120 250MCM150 300MCM185 350MCM240 450MCM300 600MCMTable 4/20 * äquivalent AWG Size0.51 0.41 0.31 0.161 0.049 0.164 0.0500.51 0.41 0.31 0.129 0.039 0.132 0.0400.51 0.41 0.41 0.106 0.032 0.108 0.0330.51 0.41 0.41 0.0801 0.024 0.0817 0.0250.51 0.41 0.41 0.0641 0.019 0.0654 0.020
