Copperbusbar and busbar column should be able to sustain electric stress generated by electric current of three-phase symmetrical short-circuit of 50 kiloampere and above.
铜母线和母线支柱应能承受50千安及以上的三相对称短路电流所产生的电应力。

Copper busbars are important in high-low electric apparatus, they have both effect on installation and electric conduction, therefore, the processing technic of copperbusbar is important especially.
铜排在高、低压电气设备中非常重要，而且既起安装作用又起导电作用，所以铜排的加工工艺地位更显重要。
