What kind of cable does the 380V 500KVA welding machine need? How is its load calculated?
500/0.38/1.732=760A check the data selection, recommend the use of 500--630 flat copper flexible cord
The current load is less than 1000A but for most welding spot welding work can not calculate the actual continuous job does not require the calculation on the GB 300-400 square can be in accordance with the 500KW motor line. If away from the transformer near the wire diameter can be reduced to low cost mobile aluminum can use larger diameter often
Full load current shall not exceed 1000A during spot weldingBut most of the welding machines work intermittentlyCannot be calculated in accordance with 500KW motorsThe actual work does not require GB calculation, half to300-400 square linesIf it is closer to the transformerThe line diameter can also be lowered for less frequent movementAluminum wires with large wire diameters can be used
