31、225(A)。从4mm及以上导线的载流量和截面数的倍数关系是顺着线号往上排，倍数逐次减l，即4×8、6×7、10×6、16×5、 25×4。“三十五乘三点五，双双成组减点五”，说的是35mm”的导线载流量为截面数的35倍，即35×351225(A)。从50mm及以上的导线，其载流量与截面数之间的倍数关系变为两个两个线号成一组，倍数依次减05。即50、70mm导线的载流量为截面数的3倍；95、 120mm”导线载流量是其截面积数的25倍，依次类推。“条件有变加折算，高温九折铜升级”。上述口诀是铝芯绝缘线、明敷在环境温度25的条件下而定的

32、。若铝芯绝缘线明敷在环境温度长期高于 25的地区，导线载流量可按上述口诀计算方法算出，然后再打九折即可；当使用的不是铝线而是铜芯绝缘线，它的载流量要比同规格铝线略大一些，可按上述口诀方法算出比铝线加大一个线号的载流量。如16mm铜线的载流量，可按25mm2铝线计算。计算电缆载流量选择电缆（根据电流选择电缆）：导线的载流量与导线截面有关，也与导线的材料、型号、敷设方法以及环境温度等有关，影响的因素较多，计算也较复杂。各种导线的载流量通常可以从手册中查找。但利用口诀再配合一些简单的心算，便可直接算出，不必查表。 1. 口诀 铝芯绝缘线载流量与截面的倍数关系10下五，100上二，25、35，四、三界

33、，.70、95，两倍半。穿管、温度，八、九折。裸线加一半。铜线升级算。 说明 口诀对各种截面的载流量（安）不是直接指出的，而是用截面乘上一定的倍数来表示。为此将我国常用导线标称截面（平方毫米）排列如下：1、1.5、 2.5、 4、 6、 10、 16、 25、 35、 50、 70、 95、 120、 150、 185(1)第一句口诀指出铝芯绝缘线载流量（安）、可按截面的倍数来计算。口诀中的阿拉伯数码表示导线截面（平方毫米），汉字数字表示倍数。把口诀的截面与倍数关系排列起来如下：110 16、25 35、50 70、95 120以上 五倍 四倍 三倍 二倍半 二倍 现在再和口诀对照就更清楚了，口诀“10下五”是指截面在10以下，载流量都是截面数值的五倍。“100上二”（读百上二）是指截面100以上的载流量是截面数值的二倍。截面为25与35是四倍和三倍的分界处。这就是口诀“25、35，四三界”。而截面70、95则为二点五倍。从上面的排列可以看出：除10 以下及100以上之外，中间的导线截面是每两种规格属同一种倍数。例如铝芯绝缘线，环境温度为不大于25时的载流量的计算：当截面为6平方毫米时，算得载流量为30安；当截面为150平方毫米时
