1·Copper busbar 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。

2·Copper busbars are important in high-low electric apparatus, they have both effect on installation and electric conduction, therefore, the processing technic of copper busbar 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。

3·Fix insulated copper tubular busbar on the steel framework directly and remove wall bushing and supporting insulator. It has strong vibration resistance.

直接将绝缘铜管母线固定在钢构架上或混凝土支架上，取消穿强套管和支柱绝缘子，具有较强的抗震动能力。
