75 flat cable, copper, aluminum to withstand the rated current are: copper 240-300A; aluminum: 170-220A specific applications, and the working environment, carrying current duration, carrying voltage related. The following table can be used as reference industry also has formulas, for the use of the site estimates, not in the engineering design, standard production use. . copper cable carrying capacity dictation: (estimated value) 2.5 times multiplied by nine, up by a straight walk; thirty five by 3.. both groups of five points; , High temperature Jiujiang copper upgrade; pipe root number two three four, eight seven six fold full load. . aluminum core cable carrying capacity dictation: (estimated value) aluminum core insulation line with the capacity of the multiples of the relationship between the number of five, 100 on the second, .. four, three circles, ... Wear, temperature, eight, nine fold; bare wire plus half; copper upgrade operator.
