How much square is the voltage of the 100 kW butt welder with 380V?
If the maximum gear is used, you can count it.100KW/380V/3P, this is the current of each phase. (I=P/U, if it's single-phase, you don't have to remove 3.)The re current divided by 5-8 is the current carrying capacity per square copper wire.If it is not the maximum gear, it is possible to have a smaller cable.
Basically, at 270 currents, 90 square copper wires would be fine
95 square 60KW GB, no 100 specifications
