(1)本节口诀对各种绝缘线(橡皮和塑料绝缘线)的载流量(安全电流)不是直接指出，而是“截面乘上一定的倍数”

来表示，通过心算而得。由表53可以看出：倍数随截面的增大而减小。

“二点五下乘以九，往上减一顺号走”说的是2．5mm’及以下的各种截面铝芯绝缘线，其载流量约为截面

数的9倍。如2．5mm’导线，载流量为2．5×9＝22．5(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3．5倍，即35×3．5＝

122．5(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0．5。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2．5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。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。
