Gb copper bar load table estimation method: estimation method: single copper bus bar load rate = width (mm) X thickness coefficient double bus bar load rate = width (mm) X thickness coefficient X 1.5(empirical coefficient) copper bar and aluminum bar can also be based on the square number, usually copper should be 5-8A/ square, aluminum should be based on 3-5A/ square Calculation method of the common copper bar carrying capacity: calculation method of the common copper bar carrying capacity at 40ºC = the width of the row * thickness coefficient of the row width (mm); Thickness coefficient: when the busbar is 12 thick, it is 20; It is 18 when it is 10 thick; [12-20, 10-18, 8-16, 6-14, 5-13, 4-12] Double layer copper bar [40ºC]=1.56-1.58 single layer copper bar [40ºC] (determined according to section size) 3 layer copper bar [40ºC]=2 single layer copper bar [40ºC] 4 layer copper bar [40ºC]= single layer copper bar [40ºC]*2.45(this choice is not recommended, using special-shaped bus bar Substitute) copper bar [40ºC]= copper bar [25ºC]*0.85 aluminum bar [40ºC]= copper bar [40ºC]/1.3 for example, TMY100*10 loading: single layer: 100*188=1800(A)[refer to the manual for 1860A]; Double-layer: 2(TMY100*10) load: 1860*1.58=2940(A); [Reference manual: 2942A]; Layer 3:3(TMY100*10) load: 1860*2 = 3720(A)[manual for 3780A] All the above calculations are accurate to the manual data are quite close.
