How many coarse copper core cables should be used for the butt welding machine for 100kW?
The temporary load rate of the welding machine is very short, although the power is short and the power is large, the current is:I = P/U = 100/0.38 = 263 (A)Because of its load rate of less than 10%, the transient overload of the wire will not be a problem, the experience data from the 16 square copper core wire can be loaded (in experience).

The load rate of the 100kW welding machine is generally 25%-30%, with an average power of 25-30 kW, and an estimated current of 380 volts. The average current is about 30000/380=78A 25 square millimeter copper core cable is recommended. If the load rate is low, the 16 square millimeter copper core cable can also be used
